Hello, I have a computer with a HD5850 and Intel i7. Since only a few projects support ATI GPU's I decided to run my GPU with the milkyway project. However I want to run my CPU with rosetta@home. Is there any way to achieve this? What I want is to only run GPU tasks with milkyway and using all CPU power on rosetta. If I manually suspend the milkyway CPU WU's, it stops getting new GPU WU's and I can't really find a way to solve this. All help is appreciated, thanks! |

The GPU is supplied with work by the CPU, so you need both for GPU work. A computer with a multi-core CPU will do what you want, with part of one of the cores doing the 'feeding' of the GPU. |

Ok, but milkyway is stealing all 8 cores, leaving none to rosetta, which is the main problem. Is there any way to force milkyway to only use 1 CPU core? |

No, but you can set Milkyway up through its project preferences not to use the CPU. Mind, this is a bit of a misnomer as the applications will still run on the CPU, it's just that the GPU does all of the calculations, while the CPU takes care of transporting the data to the GPU's memory and back. Which is what that 0.03 CPUs stands for (or whatever the number is on your system). |

Thanks, it's working just the way I wanted it to (running 8 rosetta WU's and 1 milkyway GPU WU). I'm still kind of green with BOINC and its features, but nonetheless, thanks! |
