The way the gni btl is currently coded, it will run completely out of gas on KNL at 123 processes/node. Since there are bound to be those who try to run a MPI process/hyperthread on KNL nodes, the fma sharing mode needs to be requested. merge from open-mpi/ompi#1799 Signed-off-by: Howard Pritchard <howardp@lanl.gov> (cherry picked from commit open-mpi/ompi@8b53487)
