Hi Evan, You may want to add this to the launchers. I am not sure if it is striping or stripping (c.f. today's call). Best, B

It is PAMI_ENABLE_STRIPING. It's not compatible with explicit binding, and testing to date by the HPL team @ NVIDIA shows that explicit binding is generally the optimal approach, though enabling striping is certainly easier.

Also note that there appears to the bug in IBM's MPI currently, such that GPU-awareness cannot be enabled together with striping.
