Abstract: Non-Volatile Memory (NVM) is a byte-addressable, high capacity, high latency, and persistent form of memory that can extend the primary memory hierarchy by another level. It allows clusters to have significantly greater memory capacity per node. Intel’s Optane DC Persistent Memory Module (PMM) is a NVM device that can be used to increase the memory density of high performance computing (HPC) system. With higher memory density, we can run scientific computing applications with larger problem sizes on fewer compute nodes than on current HPC systems. Smaller HPC clusters will reduce the cost of running scientific simulations. We test our hypothesis by running a HPC application with large problem sizes on a single node with NVM and on multiple nodes connected by a high speed interconnect with equivalent amount of volatile memory. We compare the performance characteristics and power consumption of both systems.
