Hello again,

I found a simple solution for my problem: there is a <<Max # CPUs>> setting in the Amicable Numbers preferences. Setting this to a low value like 2 solves the problem for me.
Nevertheless the high core count WUs should be paused, when the boinc preferences do not allow such high CPU usage.

Kind Regards

Nevertheless the bad thread synchronization for high thread count WUs should be improved.

Hello,

another problem with the multithreaded WUs is, that these do not respond when the maximum % of CPUs to be used is reduced. This is very annoying. When I use my computer I reduce the maximum CPU usage for responsiveness. The multithreaded WU's are not paused and the CPU usage remains at 100%. This is also annoying. Is there any advantage of multi-threaded WUs or do these just disable standard BOINC features (CPU limit) and block CPU cores when finishing unsynchronized?
If not, please disable them.

Kind Regards

Hello,

I am often observing WU's using less than 20% of my CPU Cores for the last !hours. All cores remain blocked until the WU finishes. This is very annoying. Could you not rather stop handing out multi threaded WU's in favour of many single threaded ones? This is very annoying. (example: amicable_10_21_7931_1619190902.985930_400_0)

Best Regards
