The multi-CPU tasks are not working correctly on at least two of my machines.

The machines are limited to using 6 cores of their i7 CPUs, however tasks from Milkyway that say Running (6 CPUs) only use one core.

This simply prevents the machines from doing any other work while those tasks are running.

I have seen this work correctly before but sometime in the last month or two something has changed.

If I can offer any more information to help find the problem let me know!

I think that is how they are supposed to work, use as many cores as you allow when it needs to, but then they back off when it doesn't need them. Not releasing the unused cores has long been a complaint here.
