Folding@home Configuração FAQ


Tabela de conteudos:
- Introdução
- Opções gerais
- Opções unicas para a versão 5.x
- Assuntos especiais



Introdução

O cliente Folding@home pode ser configurado de muitas maneiras diferentes. A razão para este leque de configurações serve para os doadores escolherem a quantidade de recursos que querem doar ao Folding@home. Em baixo estão listadas alguns controlos de configuração e o seu impacto no cliente FAH. Note que certos controlos irão levar a projectos experimentais, que serão muito menos estáveis ou mais complexos, e não são para máquinas em ambientes onde a sua estabilidade ou a sua utilização sao a principal preocupação(ex. Empresas ou ambientes educacionais). Também, note que os clientes destinados à performance(SMP, GPU, PS3, etc.) por norma usam muitos recursos e devem ser corridos unicamente em máquinas que possam tolerar trabalho pesado.
Muitas opções ou argumentos irão levar a projectos com pontos de bonus. Note que os pontos de bonus sao recompensados pelas exigencias adicionais que podem ser precisas no seu sistema ou devido à complexidade das unidades de trabalho. As unidades de trabalho com um bonus não são aconcelhaveis a máquinas em ambientes de grande fiabilidade, e só devem ser usadas com extremo cuidado e com grande Familiaridade com o FAH. Nunca devem ser usadas em máquinas que não são monitorizadas regularmente. Os pontos de bonus podem ser ajustados ou retirados a qualquer altura.


Opções gerais

A configuração por defeito não usa argumentos. A maneira mais estável de correr o FAH é sem nenhum argumento e com as respostas que vêm por defeito nas opções de configuração. O cliente irá obter uma variedade de unidades de trabalho. A maioria de unidades de trabalho relacionadas com doenças são aribuidas a clientes sem nenhum argumento.


-advmethods Este argumento Pede unidades de trabalho com metodos avançados. Estas unidades de trabalho são inerentemente menos estaveis que as unidades de trabalho regulares. O doador deve monitorizar o cliente regularmente e deve relatar qualquer situação incomum para a Folding community forum.


Opções únicas para a versão 5.x

A configuração aceita unidades de trabalho maiores que 5MB, para unidades de trabalho maiores (maiores tanto do tamanho de download, tamanho de upload, ou requisitos da RAM). Note que essas unidades de trabalho são as mais exigentes em download e/ou para a RAM. Na Consola do cliente FAH, este é definido na configuração do cliente( mudanças podem ser feitas o –config flag). Irá ser feita a pergunta “Permitir a recepção de unidades de trabalho e o envio do resultado do trabalho maior que 5MB [sim/não].” No cliente GUI, isto é feito através do painel de configuração. Não recomendamos a opção de unidades de trabalho maiores que 5MB a clientes com modems, devido aos grandes ficheiros envolvidos(e maior potencial para problemas de transmissão ou a perda da unidade de trabalho). No cliente V6, as opções para as unidades de trabalho maiores que 5MB são “[pequena, normal, grande]?” o que equivale a menores que 5mb, entre 5MB e 10MB, e maiores que 5MB.

Partes a traduzir da FAQ: http://www.stanford.edu/group/pandegroup/cgi-bin/edit/Portuguese/FAQ

!!Project details, big picture

!!!What is Folding@home? What is protein folding?
Folding@home is a distributed computing project, that very simply stated, studies protein folding and misfolding. Protein folding is explained in more detail in the [[{$Group}/Science|scientific background]] section.
Clicar para expandir...
!!!What is distributed computing?
[[http://en.wikipedia.org/wiki/Distributed_computing|Distributed Computing]] is a method of computer processing in which different parts of a program, or different portions of data, are processing simultaneously on two or more computers that are communicating with each other over a network, or through the internet.
Clicar para expandir...
!!!Who "owns" the results? What will happen to them?
Unlike other distributed computing projects, Folding@home is run by an academic institution (specifically the [[http://folding.stanford.edu/English/About#ntoc1|Pande Group]], at [[http://www.stanford.edu|Stanford University's]] - [[http://www.stanford.edu/dept/chemistry|Chemistry Department]]), which is a nonprofit institution dedicated to science research and education. We will not sell the data or make any money off of it.
Clicar para expandir...
Moreover, we will make the data available for others to use. In particular, the results from Folding@home will be made available on several levels. Most importantly, analysis of the simulations will be submitted to scientific journals for publication, and these journal articles will be posted on the web page after publication. Next, after publication of these scientific articles that analyze the data, the raw data of the folding runs will be available for everyone, including other researchers, here on this web site.

!!!How can I see how many other people are participating? What has been "folded" so far? And how much have I folded so far?
We keep many types of statistics of users and work accomplished in our [[{$Group}/Stats|Stats]] section. You can check your Individual stats, Team stats, and overall Project stats. Please also review the [[{$Group}/Papers|Results]] and [[{$Group}/Awards|Awards]] sections.
Clicar para expandir...
!!!Why don't you post the source code?
Most of the critical parts of FAH are publicly available. The Tinker and Gromacs source codes can be downloaded and run. Unlike many computer projects, the paramount concern is not functionality, but the scientific integrity, and posting the source code in a way that would allow people to reverse engineer the code to produce bogus scientific results would make the whole project pointless.

!!!What has the project completed so far?
We have been able to fold several proteins in the 5-10 microsecond time range with experimental validation of our folding kinetics. This is a fundamental advance over previous work. Scientific papers detailing our results can be found in the [[{$Group}/Papers|Results]] section. We are now moving to other important proteins used in structural biology studies of folding as well as proteins involved in disease. There are many peer-reviewed and published in top journals (Science, Nature, Nature Structural Biology, PNAS, JMB, etc) which have resulted from FAH. Currently, the FAH project has published more papers than all of the other major distributed computing projects combined!
Clicar para expandir...
!!!Why not just use a supercomputer?
Modern supercomputers are essentially clusters of hundreds of processors linked by fast networking. The speed of these processors is comparable to (and often slower than) those found in PCs! Thus, if an algorithm (like ours) does not need the fast networking, it will run just as fast on a supercluster as a supercomputer. However, our application needs not the hundreds of processors found in modern supercomputers, but hundreds of thousands of processors. Hence, the calculations performed on Folding@home would not be possible by any other means! Moreover, even if we were given exclusive access to all of the supercomputers in the world, we would still have fewer computing cycles than we do with the Folding@home cluster! This is possible since PC processors are now very fast and there are hundreds of millions of PCs sitting idle in the world.
Clicar para expandir...
!!!Can I run Folding@home on a machine I don't own?
Please only run Folding@home on machines you either own or on which you have the permission of the owner to run our software. Any other use of Folding@home violates our license agreement (and just isn't a good idea in general).

!!!What are the minimum system requirements?
All computers can contribute to Folding@home. However, if the computer is too slow (e.g. wasn't bought in the last 3-4 years or so), the computer might not be fast enough to make the deadlines of typical work units.
Clicar para expandir...
!!Networking problems

!!!My client was assigned to the IP address 0.0.0.0. What's up?
From time to time, we may not have work that matches the requirement of every platform. When that is true, we will not supply you with duplicated work that really isn't needed. We'd rather have some clients idle and repeatedly rechecking for new work than busy for long periods working on something that doesn't need to be completed. Even though your computer may see occasional idle periods, we still value your donations. If this continues for an extended period of time, be sure to ask for help in the [[http://www.folding-community.org|Forum]] because that's not normal.

!!!I have a modem; can I use Folding@home?
Yes. It can be configured to dial up automatically, or wait until you connect. There may be some problems with modems and the screen saver version. If you are experiencing any, please use the console version of Folding@home.

!!!I'm behind a firewall. Can I use Folding@home?
Yes. Please configure your Firewall or Proxy server in the configuration panel. You can reach the configuration panel by right clicking in the graphical display or by clicking on the task bar icon.

!!Errors

!!!Folding@home Windows installer doesn't do anything.
If you are attempting to install the Windows graphical client or screen saver, and see "Setup is starting..." pop up, but then nothing else happen (no error message even), the problem is likely due to the presence of files named "setup.exe" in some directory present in your path (likely culprits are the directory in which the FAH installer is, your Desktop, or your temp directory). Remember that you may have multiple temp directories, depending on your operating system. Rename, move, or remove the setup.exe files and all should work fine.

!!!Folding@home looks strange (windows) or segfaults (Linux).
Folding@home requires at least 64 MB of RAM. Weird things happen under windows with less memory and the console client simply segfaults under Linux under low memory conditions.

!!!My screen saver just looks like a black screen with little dots floating around.
We think we have diagnosed this problem. It appears to be caused by a monitor or graphics card that does not support 8-bit color. Also, we have found problems with old graphics drivers. If you are having problems, please make sure that you have the most recent graphics and OpenGL drivers.

!!!Windows asks for some DLL. Where can I find it?
Microsoft has these DLLs on their site. In particular, you need DLLs for winsock2 and OpenGL. These are built into most copies of Windows NT, 98, and 2000. However, many copies of Windows 95 do not have these.

* The Windows socket 2 update for Microsoft Windows 95 resolves a number of Winsock2 issues. This update also resolves a number of TCP/IP stack issues.
* OpenGL 1.1 for Windows 95 is included in the Windows 95 OSR 2 release. The libraries are also available as the self-extracting archive file on the Microsoft ftp site at ftp://ftp.microsoft.com/softlib/mslfiles/opengl95.exe. This contains opengl32.dll which is needed to run OpenGL programs under Win95.

!!!I get an error like "Format:MyForm not found" when I try to download.
This appears to be an error with Stanford's server, not our computers, and we are trying to identify the exact cause of the problem. It is fairly rare, however, and for now we suggest trying again at a later time.

!!!I get an error like "Network Recv Timeout" or in the console version (or in the file scrlog.txt).
If you get something like...

Deleting files IP = 171.64.122.81
Network Recv Timeout
GetWork Failed

...then don't worry. It is having problems connecting to the server, and is waiting to try again. We have a server problem occasionally, and users may have this same problem. Please wait patiently for a while, and it will connect. If it fails to connect for a day or so, it might be best to start it over again or reinstall. For the console version, hit ctrl+c to exit gracefully, and start it again. (Note: this feature was recently added in, so it may not work for your version, and you may have to kill it instead.)

!!!I get an error "Running self tests...test failed, error -1" in the console client (or in scrlog.txt), but it seems to be running.
Don't worry, if it seems to be working fine, it is. This error message is part of the Cosm distributed computing library upon which Folding@home is based, and as far as we have been able to tell, does not affect normal functioning of the Folding@home programs.

!!!I get an error "Running self tests...test failed, error -1" in the console client (or in scrlog.txt), and it dies.

Uninstall, make sure the Folding@home folder in the "Program Files" folder has been removed, and reinstall. Most of the time, this should work.

!!!When I'm running the screen saver, it crashes, and says something about a page fault.
If you get something like this:

The error message reads FOLDINGATHOME caused an invalid page fault in module…

FOLDINGATHOME.SCR at 015f:00420494.

…followed by a bazillion dialog boxes you have to click away, there is not enough memory for the screen saver to start. Suggestions for solving this are closing other applications when the screen saver is running, and setting the wait time higher (perhaps 5 or 10 minutes), so that the screen saver won't come on while you are working.


!!!Open GL games don't work or get minimized when running the FAH graphical client.
OpenGL games don't work or get minimized when running the FAH graphical client. There is a known issue that can occur when running FAH and any other application that uses OpenGL, which are mainly games. This issue is not due to FAH itself, but rather that OpenGL, which is used in the FAH graphical client, does not allow itself to be used by two programs simultaneously. The workaround for this issue is to uninstall the FAH graphical client and install the console client. Thanks to [Spectre] and ellroy80 for contributing this FAQ entry.

!!Folding@home and Genome@home

!!!What is the Genome@home project and how does it relate to the Folding@home project?
Genome@home was another distributed computing project from the Pande Group Lab. As of April 15, 2004, the project has concluded. You can find more details at http://genomeathome.stanford.edu

The goal of Genome@home is protein design and its applications. One central application of ours for protein design is the creation of large libraries of designed protein sequences, in a sense "redesigning" or "reverse-engineering" an existing Genome (hence the name "Genome@home"). Another application of protein design is to understand why proteins fold and why they misfold and aggregate. This is a central question of Folding@home and directly relates to our study of protein folding and misfolding, as it is related to misfolding-related diseases, such as Alzheimer's, ALS, etc.

!!!What does the 'gah' selection do now?
We have developed certain work units that do not lead to new work and hence do not need deadlines. These so-called "timeless" WUs are on a server and you can request one with the gah selection in the client. These WUs are best for slower machines or machines which are not connected to the Internet. The client is capable of caching these WUs as well. For clients version 5.00 and newer, deadlineless WUs are listed explicitly.

'''Notes:'''\\
'''* Recently, deadlineless WU's have been unavailable due to the science we have been studying (which is not compatible with them), but this WU type may return.'''\\
'''* When you configure a slower machine for deadlineless WU, you will be assigned ONLY deadlineless WUs (and nothing else) so your machine may remain idle for many, many months.'''\\
'''* For systems that can meet the deadlines, please reconfigure the client to accept normal work units.'''



!!Running

!!!I just finished a WU and now I got another for the same protein. Is there something wrong?
No, everything is fine. We're studying the dynamics of several proteins, so you may receive work units from the same protein (and same project number) multiple times. Each WU gives us additional information about the dynamics of that protein, so it is important to us. Indeed, if we did only 1 WU per protein, we would not learn very much. A Project number, and a Run, Clone, and Generation number distinguish each work unit.

!!!Does Folding@home run on dual processor or multi-core machines?
Yes you can by running one of our high performance SMP clients, Linux-64, OSX/Intel, or Windows.

For other platforms, additional processors must run the more than one console client (with the "-local" command-line argument if run on Windows). First, make additional directories for each processor and copy the FAH Console executable file into each. Then configure them with the -config switch, filling in settings for each. It is very important to make sure that under the "Advanced Settings" option each copy is given a unique machine ID (from 1 to 8, up to 16 on v6 clients). The first copy will default to a machine ID of 1, so additional copies should be given IDs of 2, 3, 4, etc. Each may then be run out of their installed directory, using the -local switch on Windows.

!!!Is there anything special I should do to run on a cluster?
The main aspect to consider is to make sure that the CPUID for each machine is unique. To help fight from having duplicate IDs, the Windows versions (v3 and later) keep their IDs in the registry and the Linux version (v3.11 and later) keep it in a special file MachineDependent.dat.

Ways to avoid duplicating IDs:

# If you install each client individually, then it's impossible for there to be problem with a duplicate ID.
# If you use the recent Windows version and have single processor machines, then you should also be fine (for duals, see the above).
# For a Linux cluster, make sure that if you copy the directory, you DO NOT copy the MachineDependent.dat file. This file will be auto generated by the client to get a new ID.

!!!Why should I update my Folding@home software to the current version?
We are continuously improving the Folding@home software and adding new features. We release new versions to fix bugs reported by the users to help make the project run as smoothly as possible.

!!!How do I run the screen saver when nobody is logged on (for screen saver client version 4 and earlier)?
We encourage having the screen saver running when nobody is logged in in order to get the most useful running time possible. In order to do this you must edit the Windows registry. You can do this by using the program regedit (or also regedt32 in Windows 2000), usually located in the C:\WINDOWS folder. If it is not there, you can find it by using the "Find" utility in the Start menu. It might be necessary to have administrator privileges to do this. If you don't have administrator privileges, try to convince somebody that does to do this :)

Once you start regedit, expand the HKEY_USERS folder by pressing the plus sign next to it. Then expand the .DEFAULT folder, then the Control Panel folder, then the Desktop folder. Select the Desktop folder, and you should see a list of names and data in the right hand window. Select the ScreenSaveActive name, right click, and select modify. The value should be set to one. This guarantees that the screen saver comes on when nobody is logged in. Next select SCRNSAVE.EXE, and change it to winfah.scr. (It might be necessary to set it to the absolute location, something like C:\windows\winfah.scr - wherever it's located). This selects the Folding@home screen saver as the default screen saver, when nobody is logged in. Finally, select ScreenSaveTimeOut and change it to 60. This makes sure that the screen saver comes on promptly (60 seconds, as a matter of fact) after somebody logs out.

So, to summarize, to run a screen saver when nobody is logged on, update the registry keys:
key

value
HKEY_USERS\.DEFAULT\ControlPanel\Desktop\ ScreenSaveActive
1
HKEY_USERS\.DEFAULT\ControlPanel\Desktop\ SCRNSAVE.EXE
winfah.scr
HKEY_USERS\.DEFAULT\ControlPanel\Desktop\ ScreenSaveTimeOut
60

!!!How do the results get back to you?
Your computer will automatically upload the results to our server each time it finishes a work unit, and download a new work at that time. At this time, there may be problems if your computer is only connected to the Internet sporadically. We are working on better support for these cases. Only the console version currently works over a modem connection, and there still may occasionally be a few bugs with that. v4 and later clients have improved connectivity.

!!!Can I download more than one unit at a time?
The algorithm we use works best if everybody downloads one work unit at a time, and checks back after each unit is completed. Therefore no option to download multiple units is available. If you have multiple processors in your computer, it is possible to have each processor work on a different unit; see what to do [[http://folding.stanford.edu/faq.html#run.dual|here]]. Don't try to run two copies on different machines that use the same directory on the same file system, either. Each client NEEDS to run in a separate directory.

!!!How long does it take to finish a work unit? How do you measure a work unit?
This varies, of course, on the speed of the computer and the size of the protein under study. Depending on the protein and the property studied, different size work units may be used. The [[http://fah-web.stanford.edu/psummary.html|Project Summary]] page has information on particular proteins' sizes and the deadline allotted each for completion.

!!!Can I run both the screen saver and console version at the same time? What happens if I run two console versions?
Yes, but ONLY if you install in different directories. Also, DO NOT just copy the files from one directory to each other. This will cause our server to get confused.
# You won't get credit for the work you do.
# It will be no use for science.
Instead, install a client once into each directory. If you have already copied the program into multiple directories and are trying to run it, find the client.cfg file and delete it. The next time the FAH client starts, it will create a new client.cfg file and get a new ID from the project servers.

!!!How can I make sure my results are being sent back and used? How can I tell how much work I've processed?
To find out data that has been reported back you can check the [[{$Group}/Stats|Stats]] page for Individual stats, Team stats, and overall Project stats. If your computer is returning data, you should see your username there along with the number of work units completed. If your name isn't there, and your screen saver or console version seems to be working fine, then either it hasn't finished a unit yet (this can take a few days, or even longer with an older computer), the list hasn't been updated yet. Check back in a day or two, and it should be there . . . as long as you remember correctly what you typed in for your donor user name. :)

!!!Why does adjusting the core process priority via the task manager not affect its performance?
!!!How do I manually adjust the priority of the Folding@home core?
Currently when users try to change the priority of the core via the Windows NT/2000/XP task manager this does not affect how much CPU the core gets. The reason for this is that the work is done by the core thread, which is fixed to run at idle priority and is not affected by the task manager priority for the process (which displays as 'normal' by default). In order to change the priority manually users must use a program that allows thread-level priority adjustments.

!!!Can I run Folding@home when SETI@home is running?
Yes, SETI@home and other distributed applications can be run alongside Folding@home, provided you have enough system memory. Some programs, including SETI@home run at a higher priority than Folding@home, which prevents Folding@home from progressing if it is run at the same time. If you notice that Folding@home is not progressing, you can fix this by enabling the "Slightly Higher Priority" Option in Folding@home. This can be done through the advanced options page for the Windows client, or by running "FAH2Console -config" for the console versions.

!!!Are there any limits to how long my machine can take to finish a work unit (WU)?
Yes. Depending on the work unit, unfinished work units for most projects "expire" and are reassigned to new machines. Since finishing WUs generates new WUs, we must keep things moving along by expiring units. As we move to larger and longer WUs we will extend this time as needed. Expirations vary on the order of a week to a few weeks, depending on the nature of the WU. You will get stats credit for all units that you complete, even if they have expired, but they will not be as useful scientifically.

!!!Can I run the Linux version on FreeBSD?
Yes. Please do the following:

Install emulators/Linux_base from FreeBSD CD.

Edit /compat/Linux/etc/yp.conf and put the correct server in there.

Download the Linux folding console (FAHxConsole, where x is the version number) and cd to the directory.

% brandelf -t Linux FAHxConsole

As of Version 3.24, all you have to do from here is specify the "-freeBSD" flag when you run the client,

% ./FAHxConsole -freeBSD
and it will automatically brand the scientific cores it downloads. For clients prior 3.24, the -freeBSD flag is not supported and you have to do the following:

after starting the client, wait till it download the core than kill the fold job.

% brandelf -t Linux FahCore_65.exe

% ./FAHxConsole

and you're done! (Thanks to "gotti" for the suggestion).



!!!What about OpenBSD?
It works almost as easily as FreeBSD (see the FAQ entry just above). Just follow these steps:

1. Install /usr/ports/emulators/redhat/base from ports on 3.4 or later. If you're on an earlier version, or just prefer packages, install redhat_base-8.0p2.
2. Set up a script that redirects the brandelf call to elf2olf, so that core binaries can be marked properly. This script can be downloaded from http://www.schnarff.com/brandelf, or simply set up on your own:

#!/bin/sh
elf2olf -v -o linux $3

In either case, make sure the brandelf script is executable and in the path of the user running FAH.
3. Make sure to use the Linux Console version B, as version A will coredump.
4. When running the client, use the -freeBSD switch, so that it will automatically mark core binaries properly.

Thanks to Alex Kirk for the OpenBSD info.

!!!What is simulation instability?
The simulation of molecular motion involves a great deal of computation. Each run consists of a number of time steps (each very small). At each time step, the position of the various atoms is calculated and updated, based on a number of factors. Sometimes, the simulation enters into a state that is not legal (i.e. atoms are too close, bonds are in impossible angles, etc.). At times like this, the Core exits, and information is uploaded to the server. The client will then get another assignment. If your computer is stable, then you haven't done anything wrong. On unstable computers, it is possible that the simulation instability was brought on by a fault of the system rather than something intrinsic to the work unit. Because of this, a work unit may be sent out again at some time if it is returned as having run into instability. In a given project, we expect a small percentage of units to encounter legitimate instability.

!!!What if I turn off my computer? Does the client save its work (i.e. checkpoint)?
Periodically, the core writes data to your hard disk so that if you stop the client, it can resume processing that WU from some point other than the very beginning. With Tinker, that happens at the end of every frame. With GAH it happens at the end of each sequence.

As proteins become more complex and run longer, it is better to have more frames in a WU so that you don't loose so much progress if you have to restart - - hence WUs that have 400 frames instead of 100. That still doesn't take the speed of the machine into account. A fast machine completes a frame in a few minutes while a slow one may take hours, and the donor with the slow machine still doesn't want to lose 99% of those "hours" yet the fast machine doesn't really want the overhead of writing the checkpoints every "few minutes" - - and neither of them wants the upload time associated with results containing many frames.

With Gromacs, these checkpoints can happen almost anywhere and they are not tied to the data recorded in the results. Initially, this was set to every 1% of a WU (like 100 frames in Tinker) and then a timed checkpoint was added every 15 minutes, so that on a slow machine, you never loose more that 15 minutes work.

In the 4.x version of the client, you can set the 15 minute default to another value.

Thanks to Bruce Borden for this FAQ entry.

!!Statistics, teams, usernames

!!!How can I change my username (donor name)?
The simplest way to change your username is go to the configuration panel (right click in the graphical display or click on the sys tray icon). You can change your username at any time. However, old work units will remain credited to the old username.

!!!How can I join/create a team?
To create a team, please fill out this form. To join a team, just put the team's number in the configuration panel (on graphical clients) or enter the team number at the first time you run the client (for text console versions).

!!!I'm running multiple machines behind a firewall. Can they all have the same username?
Yes. They can all have the same name. Note that in the past, one needed to append #1, #2, etc to the usernames. THIS IS NO LONGER NEEDED! Thanks.

!!!Are there any characters I should avoid in a username?
We strongly recommend sticking to just letters, numbers and underscore. Right now, we reserve the characters # ^ ~ |. # is used for firewall differentiation (see above). We want to save ^ | and ~ for other problems which might come up. Also, don't put spaces in your username; please use some character like "_" instead. Finally, please note that usernames are case sensitive, so "Dave" and "dave" and "dAVE" are all different usernames.

!!!How do you decide how much credit a work unit is worth? How do you determine how many points a work unit is worth?
Before putting out any new work unit, we benchmark it on a dedicated 2.8GHz Pentium 4 machine with SSE2 disabled (more specifically, as reported by /proc/cpuinfo on linux: vendor_id : GenuineIntel, cpu family : 15, model : 2, model name : Intel(R) Pentium(R) 4 CPU 2.80GHz, stepping : 9, cpu MHz : 2806.438, cache size : 512 KB). This machine runs linux, so all WUs are benchmarked with the linux core.

We plug the results of this into the following formula:

points = 110 * (daysPerWU)

where daysPerWU is the number of days it took to complete the unit. This equation was chosen to match the points for previous Gromacs WUs to the previous point system. The upshot is that Tinker WUs will be worth more than before we set up the new points (i.e. before April 2004).

Please note that the very concept of a reference machine will mean that some WU benchmarking will vary from the performance on your machine. Even between P4s, there are significant differences in architectures over the years. Moreover, variations between FAH WUs can also lead to differences in benchmarking points.

Our goal is consistency within a given definition of a reference machine setup (described above), but beyond that the natural variation from machine to machine and WU to WU will never allow any point system to perfectly reflect what you get on your machine.



!!!How do you set the deadlines for the work units?
Each work unit is benchmarked on a dedicated 2.8 GHz Pentium 4 machine with SSE2 disabled. For most work units (although there may be exceptions, described in the next paragraph), we apply this equation

timeout = 20 * (daysPerWU) + 2
deadline = max(30* (daysPerWU) + 2,10)

where daysPerWU is the number of days it took to complete the unit. The "+2" days is there to give an additional buffer for fast WUs (to allow for servers down, etc). If 30*daysPerWU is less than 10 days, we set the deadline to 10 days, as a minimum time for all projects. The timeout is the time at which the WU is resent to another client and the deadline is the last time which we will give stats credit for the WU.

Occasionally, deadlines may be set shorter or longer than the above calculation indicates, but the reason for having deadlines at all is that the sooner we get back work units, the sooner we can put the results to good use. Also, different projects have different requirements server-side and may require shorter or allow longer deadlines (e.g. "pfold" calculations can often be run without any deadlines, whereas MREMD calculations work best with very tight deadlines). The assignment server does take machine performance into account in making assignments, thereby allowing slower machines to receive more appropriate work units.

!!!How can I get a copy of all of the current stats?
Please feel free to download http://fah-web.stanford.edu/daily_user_summary.txt or http://fah-web.stanford.edu/daily_team_summary.txt These files are updated every 6 hours. Please DO NOT run a crawler on our cgi pages. Such actions will result in your IP being permanently banned.

!!Screen saver (Windows: version 4 and earlier; OSX: all versions)

!!!Should I run the screen saver or console version?
The graphical console version shows the same info as the screen saver, just in a window. You should run it if you

* want to be running Folding@home all the time
* don't want a screen saver
* like to see the guts of what's happening

You should run the "screen saver only" version if you

* you don't want to run Folding@home all the time, just when you're not using the machine

If you're still not sure, try them both!



!!!What's the screen saver showing?
Our graphical client shows real time visualizations of the simulations being performed. The molecule drawn is the current atomic configuration ("fold") of the protein being simulated on your computer and the graph on the bottom shows the potential energy in femtosecond increments. We display the protein in a variety of visualization styles and orientations both to get a better look at the protein fold as well as simple aesthetics. The fact that the protein visualization "scrolls" out does not have any biological meaning; it's just a non-CPU intensive and visually appealing way to show the protein.

There are currently two visualization modes: Space-filling and ball-and-stick. In ball-and-stick mode, each small ball represents an atom, and the sticks represent bonds between atoms. In the space-filling model, each filled sphere represents the approximate volume that the electrons occupy around each atom. In both modes, carbon atoms are drawn in dark gray, hydrogen atoms are drawn in light gray (although some hydrogen atoms are not drawn at all), oxygen atoms are drawn in red, nitrogen atoms are drawn in blue, and sulfur atoms are drawn in yellow.

The pie charts denote the completed fraction of the current run and the fraction of the frame completed, respectively.

!!!My monitor is set to turn off after a while.
Can I still run the screen saver? Energy saving features, which turn the monitor off after a specified period of time, does not affect the screen saver. As long as the computer is running, the screen saver will continue to run and accumulate useful data, even if the monitor is off.

!!!Does the screen saver use a lot of CPU time?
The screen saver is designed to use very little CPU time. Even without any OpenGL hardware, the screen saver only uses about 5% of the CPU time for graphics. If you have some sort of OpenGL support on your graphics card, the CPU time becomes virtually zero. Since the space filling ("orb") drawing of the atoms can be seen in the process of drawing, it may look like it is taking a lot of processor space, but that delay is set by a timer, and does not occur because it takes a long time to draw.

!!!Will extra 3D hardware help make the screen saver go faster?
3D acceleration cards will make some difference for complex proteins.

!!!How do I shut down the screen saver?
The screen saver is designed so that it shuts down on mouse click or key press. It will NOT shut down by simply moving the mouse. This is to prevent users from inadvertently closing down Folding@home, since it takes a short while to start processing every time it starts up.

!!!Where did the logo come from?
Our logo is an abstract representation of our goal: to go from the protein sequence encoded in the genome to the protein's structure. The double helix on the left of the logo denotes the genome (DNA is a double helical molecule) and the arrows on the right are representations of protein structure (beta sheet structure is often drawn as ribbons with arrows).

!!!Do you have web buttons that I can download to use with links to your site?
How about this (thanks to RPH IV)


!!!How much power/money is used by keeping a FAH running 24/7 on a computer?
Roughly, a CPU uses about as much power as a watt light bulb. Here's a report on computer power management from Lawrence Berkeley government labs, and there are other references on the web you can find. Although power supplies on most computers are rated at 400 watts, average usage is lower. On average, a Pentium-type computer uses about 100 watts (if the monitor is off). So, the daily difference between off and running FAH is about 24x100 = 2.4 kWh. At $0.15 per kWh ( from PG&E here in California), this works out to about $0.36 per day. In general, lighting and climate control use a much larger share of household power than computers do. So the best bet for cutting costs and conserving energy would be to turn off lights, turn off your computer monitors (which use more power than a CPU), and turn down the heat.

!!!What about security issues?
We have worked very hard to maintain the best security possible with modern computer science methodology. Our software will upload and download data only from our data server here at Stanford. The Cores are also digitally signed (see below) to make sure that you're getting the true Stanford cores and nothing else.

How is this possible? We take extensive measures to check all of the data entering your computer and the results we send back to Stanford with 2048 bit digital signatures. If the signatures don't match (on either the input or the output) the client will throw away the data and start again. This ensures, using the best software security measures developed to date (digital signatures and PKI in version 3.0), that we are keeping the tightest possible security. Finally, the client/screen saver are available for download only from this web site, so that we can guarantee the integrity of the software. We do not support Folding@home software obtained elsewhere and prohibit others to distribute the software.


!!!Why no IRIX, Solaris, OS-2, AMIGA, Macintosh OS9, etc version?
We've been deluged by requests for other versions. Due to limited resources, we can only support a few client versions. We try to pick operating systems which are likely to be popular with donators and that we can suitably support in house. We do support BSD via its Linux emulation layer (see above).

!!!What are you going to add in later versions of the software?
A good place to hear about new versions, beta versions, etc., is the [[http://forum.folding-community.org|Folding-Community forum]].

Última edição:
Ora aqui está a minha proposta para a tradução da parte Misc vulgo diversos do sitio.

De onde veio o logótipo?
O nosso logótipo é uma representação abstracta do nosso objectivo:
Ir da sequencia da estrutura da proteína codificada no genoma até a estrutura da proteína.
A dupla hélice a esquerda do logótipo denota o genoma (ADN é uma dupla molécula helicoidal ) e as setas à direita são representações da estrutura da proteína (as estrutura da folha-beta são frequentemente desenhadas como tiras com setas).
Vocês têm botões de atalho que eu posso usar como ligações para o seu vosso sítio?
E que tal isto (agradecimentos a RPH IV)
Quanta potencia/dinheiro é necessária para manter um FAH a correr a 24/7 num computador?
Em termos gerais, um CPU usa tanta energia quanto uma lâmpada incandescente.
Aqui esta um relatório na gestão de electricidade de computadores de Lawrence Berkeley Laboratórios do Governo, e há outras referências na Internet que você pode encontrar.
Embora as maiorias das fontes de alimentação em maior parte dos computadores serem avaliadas em 400 watts, o normal é inferior. Em média, um computador do tipo Pentium usa aproximadamente 100 watts (se o monitor estiver desligado).
Assim, normalmente a diferença entre estar desligado ou a correr o FAH é aproximadamente 24x100 = 2.4 kwh. a $0.15 por kwh. (de PG&E na Califórnia), isto resultara em aproximadamente $0.36 (0.34 €) por dia.
De forma geral, a iluminação e o aquecimento usam uma maior parte da electricidade da casa do que os computadores.
Assim a melhor forma de cortar nas despesas e conservar energia seria apagar as luzes, desligar o monitor do seu computador (que usa mais energia que uma CPU), e baixar o aquecimento.
E sobre a segurança?
Nós trabalhamos muito para manter a melhor segurança possível com metodologias modernas de informática.
O nosso programa carregará e descarregará dados apenas do nosso servidor de dados em Stanford.
Os núcleos também são digitalmente assinado (veja abaixo) para garantir que você está a receber os verdadeiros núcleos de Stanford e nada mais.
Como é isto possível?
Nós tomamos fortes medidas para verificar todos os dados que entram no seu computador e os resultados que mandamos de volta para Stanford com assinaturas digitais de 2048 bit.
Se as assinaturas não foram iguais (tanto na entrada como saída) o cliente apagara os dados e começara novamente.
Isto assegurado, pelas melhores medidas de segurança de software desenvolvidas até hoje (assinaturas digitais e PKI versão 3.0), nós estamos a manter a segurança o mais apertado possível.
Finalmente, a protecção de ecrã do cliente está disponível para descarreguar apenas deste local de Internet, de forma que a nós possamos garantir a integridade
do programa. Nós não apoiamos programas do Folding@home obtidos noutro lugar e proibimos outros de distribuir o programa.
Porque não há versões para IRIX, Solaris, OS-2, AMIGA, Macintosh OS9, etc?

Nos fomos inundados com pedidos para outras versões. Devido a recursos limitados, nos podemos apenas apoiar algumas versões do cliente.
Nós tentamos escolher sistemas operativos que são abundantes entre os doadores
e que nós podemos apoiar adequadamente em casa.
Nós apoiamos BSD via emulação de camada de Linux (ver em cima).
O que vão fazer nas versões futuras do software?
Um bom lugar para ouvir falar de novas versões, versões beta, etc., é o fórum http://forum.folding-community.org

Traduzi folding como enlaçamento, visto ser uma palavra pouco estéctica não sei se gostariam de manter o original de folding. Não apresento esta tradução como versão final pois o meu conhecimento sobre este asssunto não é dos mais profundos por isso pode haver falhas a nivel técnico. Qualquer comentários e sugestões são bem-vindos.

Cumprimentos
 
Excelente trabalho :)

A tradução de folding tem sido enrolamento, enrolar...
Enlaçamento nunca tinhamos usado. De qq forma a tradução tem-nos sempre atormentado. Tb gosto mais de folding.
O ideal até q temos no nosso site e já o que está traduzido está como enrolamento é manter.
Mas isso não é problema porque se trata apenas de uma palavra. Este contributo já é excelente mesmo.
Muito obrigado :).
 
Aqui esta a minha pequena contribuicao. Assim que me for possivel contribuir mais, nao perdoo:P

nao traduzi cluster... Qualquer coisa, comentem :kfold:

Porque não usar apenas um supercomputador?
Os supercomputadores modernos são essencialmente clusters de centenas de processadores conectados por redes rápidas. A velocidade desses processadores é comparável (ou menor por vezes) às encontradas nos computadores pessoais (PC). Assim, se um algoritmo (como o nosso) não necessita de velocidade de rede, ira executar tão rápido num supercluster como num supercomputador. No entanto, a nossa aplicação não necessita das centenas de processadores existentes nos supercomputadores actuais, mas de centenas de milhares de processadores. Logo, os cálculos executados pelo Folding@home não seriam possíveis por outros meios! Ainda, mesmo que nos dessem acesso exclusivo a todos os supercomputadores do mundo, ainda teríamos menos ciclos de computação do que os efectuados com o cluster Folding@home. Isto é possível visto que os processadores do PC actuais são muito rápidos e existem centenas de milhares de PC em ‘espera’ pelo Mundo!
