Persistent Memory: The Value to HPC and the Challenges

Abstract

This paper provides an overview of the expected value of emerging persistent memory technologies to high performance computing (HPC) use cases. These values are somewhat speculative at the time of writing, based on what has been announced by vendors to become available over the next year, but we describe the potential value to HPC as well as some of the challenges in using persistent memory. The enabling work being done in the software ecosystem, applicable to HPC, is also described.
