Maybe a few dc projects use gpu so will c@h use it to utilize fully the pc hardware? |

See this thread for the answer. |

In cuda computing can Nvidia 9800 GT pair with very lower powered cpu? and/or how much would be a cpu involvement in Cuda computing? Now seti and einstein are on the Cuda road so for C@H early Cuda talks would be proactive positive gesture. |

Yes. you can use a low end cpu (celeron type and low cock speed) to feed a gpu. In most cases, you need to dedicate 1 cpu per GPU. But the clients are getting better. You would get extra benefit using a dual core, as you could \'crunch\' a normal wu at the same time as a GPU wu. GPU crunching is still young, and project developers are still trying to reduce the load imposed on the cpu by the requirements of the gpu. Getting the cpu usage to a minimum under windows is the problem. Linux GPU clients work well. And they are making progress. Look carefully at the GPU requirement of each project (Folding, GPUgrid, seti and dnet) before you jump in. The different projects have different GPU requirements. GPUgrid being the most GPU intensive. |

Running Cuda Uses GPU + 0,09 to 0,2 CPU, that gives in my case 2 wus running on CPU + 1 wu running on Cuda and 0,2 CPU - 3 WUs at the same time |
