Threads and memory management in BEAST / BEAGLE #1070

Closed CelineReisser closed 1 year ago

CelineReisser commented 5 years ago

Hi, We recently ran into a problem regarding the threads and memory management of BEAST on our cluster. We are trying to run BEAST on 56 CPUs. Despite trying to set the BEAST -threads and the BEAGLE -threads to the correct Numbers (e.g. 56), we always end up with a threading that is much too high (8100+ threads), overloading the calculation node, while CPU usage in percent remains low. We tried to set the two parameters to 1 (-threads 1 -beagle_thread_count 1), to "remove" parallelization, but we still end up with a usage of 66 threads. Is there a thread control behaviour parameter we missed?

Have a good day.

Celine

BEAGLE thread control was broken. -beagle_thread_count now correctly provides an upper cap on the number of threads that BEAGLE tries to create.
