This project is using all eight available cores while another project is trying to run. Why is that? Please check out my blog http://sciencesprings.wordpress.com http://facebook.com/sciencesprings |

This project is using all eight available cores while another project is trying to run. Why is that? G'Day Richard, The default for N-Body work units is to use up to 16 cores in multi-thread. You can change this to what you want (2,3,4,5,6,7 whatever) using an app_config.xml file (placed in your MilkyWay project directory). Speed of processing may change you would have to try it out to see what works best. I currently use 8 cores so I can fit 3 work units at once on my 12 core 24 thread Ryzen CPU.

You can change this(76957 - Posted: 6 Mar 2024, 0:26:40 UTC) (emphasis added) At least one other project which uses multiple cores does NOT require users to 'dig in the dirt' coding conf files to set core usage limits. E.g., Amicable Numbers https://sech.me/boinc/Amicable provides a setting in the project Preferences "You can set CPU core limits and fine-tune GPU here" |

This project is using all eight available cores while another project is trying to run. Why is that? Because it's an MT app, meaning 'multi-threaded', it has an upper limit of 16 cpu cores but with an app_config.xml file you can change how many cpu cores each tasks uses. Of course the trade-off is each task will take longer to run but if you are okay with that then follow the link below or above depending on how you have this thread sorted. |
