Folding Forum

Latest version (7.4.4) does assign n-1 cores to CPU. I think that is irrespective of the number of GPUs. Also note that different cores and different GPU manufacturers need different amounts of CPU, so the setting is always a "best guess" and can often be improved by tweaking.

The Pande Group's expertise is in protein analysis, not hardware optimiztion. Software to analyze all hardware combinations would be extremely complex and would contribute very little to the actual analysis of proteins. During initial installation, it makes a reasonable guess that gets a "reasonable" setup for relatively simple systems. For those who have more complex systems or who are looking for better optimizations, it's assumed that experts will figure out how best to optimize their own systems more effectively that software could possibly do so -- perhaps with the help of other forum members.
