Subject: [OMPI devel] MVAPICH2 vs Open-MPI
From: Rayson Ho (raysonlogin_at_[hidden])

See P. 38 - 40, MVAPICH2 outperforms Open-MPI for each test, so is it
something that they are doing to optimize for CUDA & GPUs and those
optimizations are not in OMPI, or did they specifically tune MVAPICH2
to make it shine??
