From 5129d84304035622d84ac61139625e4a88a686de Mon Sep 17 00:00:00 2001 From: Nithin Senthil Kumar Date: Thu, 19 Nov 2020 07:47:57 -0500 Subject: mvapich2: extended the fabrics variant description (#19860) The point of this variant is to give the end user an option to use system installed fabrics such as mofed instead of upstream fabrics such as rdma-core. This was found to avoid run time errors on some systems.
