_zZz_We will soon release a new version of SETI@home, based on BOINC, a general-purpose platform for distributed computing projects like SETI@home. Eventually other distributed computing projects (like Folding@home and ClimatePrediction.net) will also use BOINC, and you'll be able to share your computer time among projects of your choosing.
BOINC makes it possible for us to release new versions of SETI@home without requiring you to download and install new software. It will also let us do new analyses of the SETI@home data, looking for other types of radio signals (such as short pulses from evaporating black holes).
Switching to SETI@home/BOINC will be easy:
Create an account using the SETI@home web site. This will give you an account ID, sent by email. Note: accounts will created automatically for all current SETI@home users (see below).
Download and install the BOINC client program when it becomes available.
Uninstall SETI@home.
When you first run the BOINC client, enter your SETI@home account ID.
Stages of the transition
We don't have an exact timetable yet, but the transition will be staged as follows:
We will make a snapshot of SETI@home user information (accounts, teams, profiles) and will use it to initialize the SETI@home/BOINC database. We will then launch the SETI@home/BOINC project.
Over the next month or so we will send email to all SETI@home users, giving them their new account IDs and recommending that they switch to BOINC. During this period you can continue to run the current SETI@home, and your results will be recorded and used. New SETI@home accounts and team changes can be made, but will not be carried over to BOINC.
Once SETI@home/BOINC is stable, and versions are available for most platforms, we will turn off the current SETI@home server. At this point you will need to switch to SETI@home/BOINC.
What will happen to my workunit totals?
BOINC keeps track of your computer's work in terms of actual computation, not workunits. This is necessary because BOINC projects may have workunits of many different "sizes". Because of this change, all SETI@home/BOINC accounts will start with zero credit.
However, the workunit totals from the current SETI@home will be recorded in our database, and a section of our web site will show the final totals.
What will happen with SETI@home teams?
All current SETI@home teams, and their membership, will be copied over to SETI@home/BOINC. The work totals for teams will also start from zero.
What will happen with programs like SETIQueue?
These programs (which have been very useful with SETI@home Classic) won't work with SETI@home/BOINC. The function of buffering multiple work units is provided by the BOINC client itself - you can specify how much work your computer should get each time it contacts the server.
Another function of SETIQueue - acting as a proxy for hosts that are not directly connected to the Internet - can be performed in BOINC by an HTTP 1.0 proxy such as Squid for Unix or FreeProxy for Windows.
Will the format of input and output files change?
Yes. Programs which display information about the signals found in SETI@home work units will need to be modified to support the new (XML) data formats used by SETI@home/BOINC. Authors of such programs are encouraged to contact the SETI@home team for sample input and output files.
Work unit and result files will be about the same size as now. The black-hole detection project will use somewhat larger work units, on the order of 1 MB.
What platforms will be supported?
Initially Windows/Intel, Linux/Intel, Solaris/SPARC, and Mac OS X will be supported (these are the platforms to which we have access). We will continue our current source code distribution policy, and eventually we will hopefully support all platforms on which SETI@home currently runs.
Initially, the Windows version will have a graphical interface and the others will have a command-line interface. Eventually most platforms will have both interfaces available.
Can I run multiple instances on a multiprocessor
Yes, but it's not necessary; BOINC automatically uses all the processors (unless you ask it not to).
