Possible job failures due to MPI library change on Pitzer after May 20


There are changes on MPI libraries on Pitzer after May 20. We will upgrade MOFED from 4.9 to 5.6 and recompile all OpenMPI and Mvapich2 against the newer MOFED version. Users with their own MPI libraries may see job failures and will need to rebuild their applications linked against the MPI libraries.
