For a subset of compute nodes, internodal communication among them and between these nodes and the storage systems serving the home directories and the scratch directories is provided by a QDR Infiniband network(40Gbps). For another (larger) subset of compute nodes, these communications are provided by an EDR Infiniband network (100Gbps).

Teaching cluster

The teaching cluster is a Linux cluster that runs a 64-bit Linux, with Rocky 8.8. The login node is a VM that has 4 cores (Intel Xeon Gold 6230 processor) and 16GB of RAM. An EDR Infiniband network (100Gbps) provides internodal communication among compute nodes, and between the compute nodes and the storage systems serving the home directories and the work directories.

The cluster is currently comprised of the following resources:

Regular nodes:

  • 10 compute nodes with AMD EPYC (Naples 1st gen) processors (32 cores and 128GB or RAM per node)

High-memory nodes:

  • 2 compute nodes with AMD EPYC (Naples 1st gen) processors (64 cores and 1TB of RAM per node)

GPU nodes:

  • 1 compute node with Intel Skylake processors (32 cores, 192GB RAM per node) and a P100 GPU card

The queueing system on the teaching cluster is Slurm.
