I have dual P4 3.2 ghz processors on a single Gateway 710XL machine running Win XP Home Ed, SP2. I normally run 2 instances of classic seti@home under 2 different users. For other things, I use other logons and SETI just sits in the background. Running only one instance of SETI lets lots of cycles go to waste. Can I run multiple instances under BOINC? Or is there another way to get max use of available cycles for SETI with BOINC?

After you attach your computer to the project you can set your account preferences to use as many cpu's as your computer has.

Docs I reviewed didn't make this quite clear. I take it I would use the Service Installation?

It doesn't matter how it is installed. The preferences under "your account" will determine how many cpu's are used.

If I remember correctly, when BOINC is started for the first time it will only process one workunit. When that one has been successfully completed and returned then the cpu preference will kick in.

Boinc handles multiple processors pretty slick. After the first work unit or so (to get CPU speed stats I guess?) it actually runs two copies of the SETI@home software, one for each CPU.

I chose to install BOINC in all my systems using the service option. Runs great.

By the way, the default for the BOINC settings the others are talking about is to use up to two processors if they are vailable, so your P4s will be maxed out right away.
