[Swift-devel] Where is latest doc on running Swift on Beagle? Covers OpenMP apps?

Sun Oct 16 11:30:55 CDT 2011

It's in my run script that creates the actual sites file that I run with.
I'm not sure what you would do if you wanted more than 24 cores, so depth
stays fixed at 24 (that's an aprun parameters). Then

    WORKERSPERNODE=$((24/$PPN))

Where PPN is how many cores you want per OPENMP app and then workers per
node says how many OPENMP apps you want to run. So obvious example would be
you want 3 8 core OPENMP jobs, PPN = 8, WORKERSPERNODE=3
