ADDED: I noticed in the forums that others have the same problem, and that there is a workaround when a unit gets stuck. My question of whether we can actively deselect the downloading of the units still stands, though. Hi I use only my cpu for computation (basically because the bios of my computer turns off the fan at low temperatures and when the temperature rises the fan starts up. I cannot modify this setting, and the sound is a bit annoying, so I've found out that keeping the cpu somewhat busy prevents the fan from turning off). When running MilkyWay@home on cpu-units, I generally get two types of units: Modfit and Nbody. Modfit run on a single core and compute just fine. Nbody runs on 4 cores and some of them compute fine while others seem to stall and literally just get stuck for hours until I cancel them. I can tell from the fact that my cpu cools off (and the fan shuts off/restarts etc.) that it's not because the cpu is busy and just "calculates in circles" or something. I have looked around but cannot seem to find a setting to allow only single core units to be downloaded. Is this possible, or will I have to manually cancel all 4 core units every time they download? |

Yes there is click on your name in the top right corner of the page, just below the big Miklyway Boinc box, then click on Preferences for this project MilkyWay@home preferences in the middle section under Preferences. You will then see choices like this: Run only the selected applications Milkyway@home N-Body Simulation: yes Milkyway@home Separation: no If no work for selected applications is available, accept work from other applications? no The N-Body units are the multi-threaded ones you said you want while the Separation units run on a single cpu core. |

Thank you! This was exactly what I was looking for! |

Just on the topic of the 2 different CPU options, does anyone know which produces the best throughput? mt tasks or the Home separation wu's? If no one knows, I guess I'll have to do some testing. ![]() ![]() |

Thanks Mikey. I don't usually bother either but I was curious to see what credits I could push out with GPU & CPU crunching. I gave up and went back to WCG for CPU crunching :) ![]() ![]() |
