Hi, So I just loaded up Asteroids onto 6 32core machines(Dual Intel(R) Xeon(R) CPU E5-2665 0 @ 2.40GHz [Family 6 Model 42 Stepping 2]), however it's only using 78% CPU on each machine. In looking at this further, it's only running 25 WU's at a time instead of 32. Other projects can use 32 on one machine just fine.

Is this a limitation of Asteroids?

Nevermind, Looks like I need to change BOINC settings to use 100% of the CPU's instead of 0% of the CPU's...0% must have a max of 25 for some reason.

AFAIK when you have:
On multiprocessors, use at most 0% of the processors
... then the other (older) setting comes into effect:
On multiprocessors, use at most 16 processors

Also if you see "Waiting for memory" for some tasks - adjust:
Memory: when computer is in use, use at most XX% of total
Memory: when computer is not in use, use at most YY% of total
