I tried something like this with a feature called HyperthreadingBackoff in 24.15. Results were mixed - some more tuning was definitely in order. The real problem is that the OS provides very poor statistics for prime95 to use to determine if another task is making heavy use of the CPU. >Various approaches could be used and I'll propose just one: > >if (keyboard OR mouse activity) AND (niceflag=true) As others have pointed out, the real problem is not keyboard and mouse activity as this is often associated with programs that are making very light use of the CPU. The CPU-bound task such as a big compile or photo-processing job are the ones where prime95 needs to "get completely out of the way" _______________________________________________ Prime mailing list [email protected] http://hogranch.com/mailman/listinfo/prime
