[slurm-users] Hybrid compiling options

[Yair Yarom]

Hi,

We also have hybrid cluster(s).
We use the same nfsroot for all nodes, so technically everything is
installed everywhere. And we compile slurm once with everything needed.

Users can run "module load cuda" and/or "module load nvidia" to have access
to nvcc and nvidia's libraries (cuda and nvidia are manually installed here
as well), so they can compile gpu code, but it won't run on nodes with no
nvidia hardware.

The infiniband is that same, though we don't have hybrid clusters. I.e. one
cluster has IB, and one doesn't. But they all run the same binaries.

HTH,
    Yair.
