Allow only SLURM tasks
And how could I block the execution of jobs in the master node that are OpenMP programs for example, that don't make use of MPI and ssh for computing... Is there a way? 2018-04-23 14:51 GMT-03:00 Alex

Infiniband over slurm
Hello!! Thanks so much for the responses. What I want to do is use MPI over Infiniband (sorry for the misunderstanding) But I use Intel MPI, not OpenMPI or MVAPICH. Intel MPI is not supported over IB?
