2016-08-09 Thread Xiaolong Cui
I used to tune the performance of OpenMPI on InfiniBand by changing the OpenMPI MCA parameters for openib component (see https://www.open-mpi.org/faq/?category=openfabrics). Now I migrate to a new cluster that deploys Intel's omni-path interconnect, and my previous approach does not work any more.
