Talking about getting more participants, it would be great to integrate prime95 into BOINC platform. Currently BOINC running on more than a million hosts and some participants would definitely be interesting in sharing their resources for prime95 using BOINC interface.

Even though the P95 process runs at a low scheduler priority, it still uses 100% of the available CPU (obviously!), and can leave XP 'gasping for breath'. Basically, the XP scheduler is not that clever at maintaining responsiveness of forground apps when low priority tasks exist that are compute-bound. > > I was wondering if George W might consider including some extra logic in the next version of P95 to cause it to 'back-off' the CPU under some circumstances.
