So as other's have mentioned on this mailing list before, one "gotcha" with upgrading from 14.03.x to 14.11.x is that libpmi.so is linked to libslurm.so.27 in 14.03.x. In 14.11 the libslurm is named to libslurm.so.28. This can cause issues if OpenMPI or MVAPICH2 were compiled with SLURM support. I verified this is the case while testing the upgrade to 14.11.6 at my site. What I could use some input on is how safe is it to just add the libslurm.so.27 symlink to the RPM spec used to build SLURM? I manually added the symlink on my test compute nodes then ran an MPI job using OpenMPI and MVAPICH2 both compiled with SLURM 14.03 support. With the symlink manually created, the jobs ran fine under 14.11.6. I'm curious if there may be some hidden problem I'd hit later if I don't recompile all my installs of OpenMPI and MVAPICH2.
