Hi Trevor,
Actually, Slurm does not do much with IB. Whatever the underlying
network (IB, Ethernet, and so on), Slurm components require IPv4
addresses to communicate, it is not able to use low-level protocols
under IP-o-IB.
If you have Mellanox hardware it is better to use Mellanox flavor of
OFED to get all the performances with last Mellanox technologies (MXM,
FCA, etc) and get technical support from them.
Most major implementations of MPI (Open MPI, MPICH, Intel MPI and
probably others) are tightly integrated with Slurm, esp. when PMI
support is enable.
