Ok... I cant seem to find a way to get more slots.. quad core.. 4 slots for WUs to run.. Ok good :) I have a nVidia 8800.. good.. and it does well until all slots are pluged with Astro's leaving NO slot for regular WUs to run with the nVidia. So.. I set the max CPUs to use to 3 (75%).. Well guess what? It counts the CUDA as one of the Q6600's cores and BANG!.. 2 cores doing Astros and the CUDA doing one. When the third core enabled gets an Astro Pulse, than the CUDA will stop working all together as it did with 4 CPU cores enable! :( This bug needs fixed and fast so the cuda and astros can run at the same time and use all the power in my case. If there is a way to bump the slots from 4 to 5, I think that would fix it but I can't find a way to do this. Not Ready Reading BRAIN. Abort/Retry/Fail? |

Ok... <ncpus>5</ncpus> in cc_config.xml, look other threads. |

You need to create a cc_config.xml specify number of cpus to 5, and put it into your boinc folder. Check Raistmers thread for an optimized AP plus CUDA release. Then run 4 AP units and one CUDA. edit: got beaten to it... ;) |

Yes.. I just read that thread and thanks.. I will try that.. Yep.. that did the trick.. YIPPY!! Not Ready Reading BRAIN. Abort/Retry/Fail? |

I found that thread too and it sorted my problem. 4 cpu and 1 gpu now. Bambi |

Be aware that with more than one CUDA card you may see tasks in a Running state with no progress. This is because the CUDA cards are "starving" the task of CPU. I am not sure that happens here, but it did happen to me with two GPU and two running GPU Grid tasks ( a later version of the Science Application, pulled for other bugs, seemed to have fixed this) YMMV |

Also if you run out of CUDA work it will try to run the 2+1, 4+1 even if you don't have GPU work. Kind of slows down the other work. |
