I have two Hyperthreaded Xeon processors, so my RHEL 3 ES OS thinks it has 4 processors. I allow BOINC to use all 4. I have told BOINC to allow suspended applications to remain in memory (or to be paged out).

Now when climateprediction does that, what happens is that the two processes are put in STOPPED state and when the BOINC client sees fit to resume them, it does that. Thus, the times slowly increase.

But setiathome is different. It seems to put nothing in STOPPED state, yet it allows the processes to resume, accumulating time just as does climateprediction.

I do not know what Predictor does, since it will not run with the 4.05 BOINC client.

I would have though all applications would use the same mechanism for stop and resume. ???
