Yesterday (3/27/17) at 4:30 pm MST, I had this task that was ready to go: http://bit.ly/2mMFJT2

When I got in this morning (3/28/17) at 8:00 AM MST, it still hadn't ran.

I have my tasks set up to run for 60 minutes at a time.

I had to suspend all the running GPU tasks simultaneously for it to run.

It finished in 00:28:34.

Is there a priority scheduling problem with multiple GPUs on the same WU?
Seems like it would be the same as a Cosmology or other (4CPU or 6CPU task)

Please let me know any info you have.

Thanks, -Doug

P.S. How many Nvidia GPUs will be utilized simultaneously by a task like this?
I can have up to 7 cards on my MOBO.

Would 3 AMD cards work as well?

Could Nvidia and AMD be used on the same task?
