MPI Libraries for parallel jobs on Sapelo2
All compute nodes on Sapelo2 have Infiniband (IB) interconnect via EDR Infiniband network (100Gbps).
Various IB-enabled MPI libraries are available and users can set the environment variables for the MPI library of choice by loading the corresponding module file.
