University of Missouri Cluster (Lewis)

The Lewis HPC cluster is a shared cluster located in Columbia Missouri accessible to researchers and their collaborators at the University of Missouri and across the University of Missouri System. Lewis currently runs CentOS 7 and uses SLURM to schedule jobs. Lewis currently consists of the following compute nodes and storage.

217 CPU nodes with 8688 cores

  • 64 Cascade Lake nodes with 48 cores and 384GB of RAM connected with 10Gbps Ethernet and 100Gbps HDR InfiniBand
  • 35 Skylake nodes with 40 cores and 384GB of RAM connected with 25Gbps Ethernet and 100Gbps EDR InfiniBand
  • 72 Broadwell nodes with 28 cores and 256GB of RAM connected with 10Gbps Ethernet and 40Gbps QDR InfiniBand
  • 32 Broadwell nodes with 56 cores and 512GB of RAM connected with 10Gbps Ethernet
  • 11 Haswell nodes with 24 cores and 128GB
  • 1 AMD EPYC node with 64 cores and 4 Ivy Bridge nodes with 24 cores for interactive jobs and testing

14 GPU nodes with 27 cards

  • 3 NVIDIA V100S
  • 13 NVIDIA V100
  • 7 NVIDIA GTX 1080Ti
  • 1 NVIDIA P100
  • 1 NVIDIA K40m
  • 2 NVIDIA K20Xm

Shared Storage

  • 1PB HPC storage (Lustre), high speed parallel storage
  • 2.8PB HTC storage (ZFS), large economical low computational intensity project storage

The cluster is supported in part by an NSF MRI Award 1429294.
