There are not too many options for controlling the CPU input in Windows. In Linux, you can increase the priority of an individual process but you have to do it each time the individual process starts. If you overclock the video card, it will draw more CPU resources to keep feeding itself material to work on. | |

Never mind the percentage BOINC shows here. It's just a guideline and doesn't mean anything. There are not too many options for controlling the CPU input in Windows. In Linux, you can increase the priority of an individual process but you have to do it each time the individual process starts. You can easily do that under windows as well. However, writing a script which does that automatically should be easier under linux ;) MrS ____________ Scanning for our furry friends since Jan 2002 | |

There are not too many options for controlling the CPU input in Windows. In Linux, you can increase the priority of an individual process but you have to do it each time the individual process starts. Later versions of BOINC already do this under windows. The cuda cpu task runs as below-normal priority, whereas the regular crunching tasks run at low priority. I don't know if the linux flavour of BOINC does the same thing or not. ____________ BOINC blog | |

I am also runing CPU hungry project's (AQUA, MW) I want to increase CPU resources to GPUGRID. How to do this? How to increase load of CPU for GPUGRID. Cześc, I see you have 4 quad core systems, each with a GTX 260! I would suggest you just run one CUDA program on each system. I would not recommend running Aqua and GPUGRID on the same system as you may end up completing tasks more slowly because the cards keep switching to other CUDA tasks; you would therefore get less credit. If you have Aqua running on a system (say your 8200) and it is using over 0.3 CPU’s, crunch no more than 3 CPU tasks on that system. When you are using 4 CPU cores and running Aqua GPU, it usually slows down (perhaps about 15%). But a 15% reduction on your GTX 260 is much more than one core of an 8200, which will actually still mostly be used. GPUGRID usually uses the CPU less. It might be worht doing this on a Q8200 running GPUGRID, but I am not sure. I am fairly sure about Aqua though. If you want to keep running more than one GPU project on the same system, try the following: Right Click on the TASK BAR, Open Windows TASK MANAGER, Select PROCESSES, Look for the GPUGRID CUDA task that is running, under image Name or Description, right click on it and Set Priority to NORMAL. This should prioritise the GPUGRID task over Aqua & MW. You could even try setting affinities, should you be running long tasks such as Climate Change (set 3 of these tasks to use one core each, and use the other CPU core for system and GPU support). | |

On this subject; i have a cpu aqua mt app and a gpugrid cuda app and the mt app is using almost all of my cpu, and i can tell that the progress of gpugrid is slowed a hell of a lot b/c the temperature of the gpu under full load is 63-64 C and with the aqua is running it was about 55 C... | |

GPUGRID needs to use the CPU for some calculations, so it is important that the CPU is not overburdened, especially if you have more than one GPU. Some of the Aqua CPU tasks use 2.4 cores. | |
