HPC Architecture
The Montana Tech HPC (oredigger cluster) contains 1 management node, 26 compute nodes, and a total of 91 TB NFS storage systems. There is an additional computing server (copper).
Twenty-two compute nodes contain two 8-core Intel Xeon 2.2 GHz Processors (E5-2660) and either 64 or 128 GB of memory. Two of these nodes are GPU Nodes, with three NVIDIA Tesla K20 accelerators and 128 GB of memory. Hyperthreading is enabled, so 704 threads can run simultaneously on just the XEON CPUs. The remaining four nodes feature the Intel 2nd Generation Xeon Scalable Processors (48 CPU Cores and 192 GB Ram per node). Internally, a 40 Gbps InfiniBand (IB) network interconnects the nodes and the storage system.
The system has a theoretical peak performance of 14.2 TFLOPS without the GPUs. The GPUs alone have a theoretical peak performance of 7.0 TFLOPS for double precision floating point operations. So the entire cluster has a theoretical peak performance of over 21 TFLOPS.
The operating system is Centos 7.6 and Penguin's Scyld ClusterWare is used to maintain and provision the compute nodes.

3D Visualization System
Montana Tech is developing two 3D data visualization systems. Both systems provide an immersive visualization experience (aka virtual reality) through 3D stereoscopic imagery and user tracking systems. These systems allow scientists to directly interact with their data and helps them gain a better understanding of their data generated modeling on the HPC Cluster or collected in the field. Remote data visualization is possible by running VisIt from the cluster's login node.
