Our operating system is RHEL Server 7.9.  The Linux cluster is comprised of 8192 compute cores connected by low-latency Fourteen Data Rate (FDR) and Enhanced Data Rate (EDR) InfiniBand networks, with mainly Intel Xeon E5-2680 v4 and Intel Xeon Gold 6248R chips.  Also, I am using OnDemand version: v1.6.25 to run Ansys interactively.
