Milkyway@home N-Body Simulation, limit to just 1 thread and slow CPUs ?
(Message 69736)
Posted 18 Apr 2020 by ![]() Post: Yes, an app_config.xml file could do this... ;) But I'm unsure if the/my slow CPU can finish N-Body Simulation WUs (they vary a lot) during the 12 days, just with 1 thread. ;) I would like to know experiences from others which have similar slow CPUs - if it's possible to finish N-Body Simulation WUs before deadline with just 1 thread... I wouldn't like to let it run just for test, it would be waste of CPU time if it won't finish before deadline... ;) Thanks :) |

Milkyway@home N-Body Simulation, limit to just 1 thread and slow CPUs ?
(Message 69733)
Posted 18 Apr 2020 by ![]() Post: Hello :) I have just a slow CPU : Intel(R) Celeron(R) CPU J1900 @ 1.99GHz [Family 6 Model 55 Stepping 8] (4 real Cores) I would like to limit the N-Body Simulation app to just 1 CPU thread (with app_config.xml file). I'm unsure if the WUs will finish during the 12 days deadline. A Milkyway@home Separation WU lasts around 6 hours - for to compare. Just crunching, no other things at the same time. I work and play games during crunching, so the calculations time of the WUs increase... Maybe you have also a slow CPU and you limit the N-Body Simulation app just to 1 thread? I could limit the app to just 1 thread - what you think? Thanks :) |

Posted 15 Nov 2016 by ![]() Post: BTW. AFAIK, Milkyway WUs could be created/send out if results come back. The results which come from the members PCs make it possible to create new WUs. This is different to other BOINC projects. |

Run Time is higher than CPU Time because of currently SETI GPU app support. Because the currently Milkyway 1.42 ATI OpenCL GPU app don't work... ;-) - like I read here in this thread. Milkyway 1.40 ATI OpenCL GPU app made computation errors (I sent Jake a PM because of the OS error message which appeared in my Win8.1 x64 Pro). |

MilkyWay N-Body Sim., 1.62(mt) vs. 1.62(st) app - speed difference?
(Message 65133)
Posted 11 Sep 2016 by ![]() Post: For MilkyWay N-Body Sim. we could choose 2 apps and different settings... Currently, the... 1.62 (multi thread) app - all available CPU-Threads allowed 1.62 (multi thread) app - limit to 'all -1' CPU-Threads (e.g. Quad-Core CPU, 4 CPU-Threads -1 = use 3 CPU-Threads) 1.62 (multi thread) app - limit to 1 CPU-Thread 1.62 (single thread) app - use just 1 CPU-Thread I tested the 1.62 (mt) app (limited to 1 CPU-Thread) and the 1.62 (st) app ...on my Celeron J1900 Quad-Core CPU, and it looks like the 1.62 (mt) app is much slower with this config. If you have VGA cards installed, or you use the iGPU, you shouldn't run the (mt) app on all available CPU-Threads, if yes the GPU WUs stop (from my experiences). This is still like this? E.g. on a Quad-Core CPU, the (mt) app allowed to use 3 CPU-Threads is faster/slower than the (st) app? ...at the end of the day, which app crunch more WUs? E.g. on 12 CPU-Threads CPUs (2 * 6 = 12 real CPU-Cores (my dual Xeon PC, HT off ;-) )... the (mt) app allowed to use 11 CPU-Threads vs. (st) app? ...at the end of the day, which app crunch more WUs? Speed differences: (mt) app all CPU-Threads allowed vs. (mt) app 'all -1' CPU-Threads allowed? Or with the (mt) app it must be always straight numbers, like 2, 4, 6, 8 CPU-Threads for max. speed? Maybe someone made already all this tests? Thanks. |

From my experiences, the CPU should a few % idle. (If not the GPU app calculation could stand still (not feeded from the CPU) and this result in a task error.) And how much tasks simultaneously on the GPU: <count>1</count> 1 = 1 app 0.5 = 2 apps simultaneously 0.33 = 3 apps simultaneously ...
