It only uses 50% of CPU power at present, and will take 93 days to run a project, at 24h per day. I will probably upgrade the system between now and then. So if I cant set this up to work flat out there is no point starting, I will just do one of the other projects like rosetta (all my other systems use 100% CPU, and all are dual core). I dont know whats up with this project? Any suggestions on how to get the CPU use to 100% of both CPU cores? ID: 26728 · Reply Quote

It\'s not possible to run one model on both processors. But BOINC has an option, in General preferances on your Account page, to use 2 processors, and then run 2 models simultaneously.
