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

Hello again,

I have 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 bad thread synchronization for high thread count WUs should be improved.

Kind Regards
