I'm one of your BOINC to Fold converts, but have noticed that the WinGui client will only use 50% of an otherwise idle Pentium D. Poked around the settings, found a slider moved all the way to the right, but can't get it to use more than half the available resources. Othewise, glad to be aboard.

The WinGUI is using everything available... you have a processor with Hyper-Thread support. Windows treats it as a second processor, but it's not really a full-blown processor in and of itself. It merely gives the machine the capability to sometimes run two threads simultaneously, plus Windows' reporting of CPU usage is inaccurate or misleading.

Some suggest that you should run two versions of the console program to keep all available thread execution pipelines busy; I'm not in favor of that if you're trying to process work units as quickly as possible.

I posted a more detailed discussion of Hyper-Threading from the F@H support forum here for those that missed it.
