Subject: Re: [OMPI users] Compiling Open MPI 1.7.4 using PGI 14.2 and Mellanox HCOLL enabled

If you are running on a Slurm-managed cluster, it won't be happy without configuring --with-slurm - you won't see the allocation, for one.

Is it just the --with-slurm option that causes the problem? In other words, if you remove the rest of those options (starting --with-hcoll and going down that config line) and leave --with-slurm, does it build?
