I have started this folding thing and am now truly addicted. But over the past week I have noticed that based on CPU monitor both my DP450 G4 and my DP2G G5 show that the processors are just sort of loafing along- maybe 50% utilization. The fans never really kick up on my G5. Meanwhile my poor 350MTi powerbook is showing that it is floored- nearly 100% CPU usage. Did I miss something special to do during the installation? It really looks like the fact that there are dual processors is being ignored by the folding software- but perhaps this is an illusion. I am running folding in screen saver mode. I tried running the graphical client but it appeared to erase all the work of the previous screensaver. The G4 lost about a week of work. Which was sad- it takes it nearly 50 minutes to complete a frame! IN fact it appeared that they were alternately erasing whatever work the other was completing- the work completed never got above a few percent. I am sure this too is a result of some error of mine. I cannot find a clear answer about running both the screensaver and graphical client- are they compatible with running at the same time? Do they compliment or compete with each other? As an interesting note while they both were running the CPUs were running at 100% - though they never accomplished anything.
