Thanks, TB and Dr Who Fan. I'll keep this in mind. I've suspended N-Body sims from after this one completes. Hoping they figure this out soon.

TB, so I should just let it run anyway to save someone else the grief of having to deal with this one?

That didn't work. I may just have to bite the bullet and let it complete. Will take about 36 hours. Oh well.

I've got an N-Body simulation I received recently that is taking forever to complete. It will take more than 30 hours by my calculation to finish when other N-Body simulations take an hour or less. Do you know why this would be? I am attaching the properties of the WU here:

OK. Thanks, Mikey, for this information. It was a clear explanation.

Hi all. I just started participating in the project but am very disappointed that one MilkyWay WU is using 4 CPUs, preventing me from processing on my other projects. Is there a way I can get it so that the one WU uses only 1 CPU space so I can participate in the other projects simultaneously? If not, I will have to remove this project, unfortunately.

Thanks.
