I noticed some of you (somewhere in that huge F@H thread) were talking about running two instances of Folding At Home -- one on each core of your dual-core or dual processor system.
I tried running more than one instance of F@H (Windows version 5.03) on a older dual processor Pentium III as well as a hyper-threaded Pentium 4. In both cases I immediately got an application error message saying essentially, "can't run more than one copy of F@H, this copy is quitting." I tried the obvious trick of setting processor affinity to the first pair of Folding processes running in memory (FAHcore_xx.exe and WinFAX.exe) before I launched the second instance of F@H. That did nothing to resolve the problem.
Thanks in advance,
Mr. Clueless At Folding
