Academic Compute Cluster (UB-HPC)

CCR General Compute Cluster.

CCR's general compute cluster for academic users is made up of over 16,000 CPUs in various configurations.  Many of these servers are kept cool by individual air conditioners and sealed doors.

IMPORTANT: Users submitting MPI jobs need to add the IB constraint

The UB-HPC cluster has some compute nodes that do not have InfiniBand/OmniPath.  Please add the "--constraint=IB" or "--constraint=OPA" as needed to your SLURM scripts.  

#SBATCH --constraint=IB
