Description: 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's currently runs CentOS 7 and uses SLURM to schedule jobs. It currently consists of 54 Haswell nodes with 24 cores and 128GB or 256GB of RAM and 81 Broadwell nodes with 28 cores and 256GB of RAM and 37 Broadwell nodes with 512GB of RAM connected with 10 Gigabit Ethernet and 40 Gigabit QDR Infiniband.  It also consists of 35 Skylake nodes with 40 cores and 384GB of RAM connected with 25 Gigabit Ethernet and 100 Gigabit EDR Infiniband for a total of 6200 cores.  There are also 144 Sandy Bridge cores for interactive jobs and testing.  There are currently 17 GPU nodes with 8 NVIDIA K20m GPU's, 2 NVIDIA K40 GPU's, 1 NVIDIA P100, 16 GTK 1080Tis, and 6 NVIDIA v100 for a total of 32 GPU's.  The system is connected to 595TB of shared high speed parallel HPC storage (Lustre) for computation and 1240TB of HTC storage for large economical low computational intensity project storage (ZFS).
