NVM and HPC – Is there a use case?

Prof. Dr. André Brinkmann, Johannes Gutenberg Universität Mainz

13 Feb 2017, 16:30–18:00; Location: S2|02-C120

Parallel file systems (PFS) have been developed to support typical HPC applications, where most file system operations include reading or writing huge chunks of data, which can be easily striped over the storage backend. New data-intensive applications will change these patterns and small random I/Os will occur more frequently in HPC, missing the sweet-spot of today’s parallel file systems. At the same time, supercomputers start to include node-local flash-storage or NVRAM, offering the opportunity to decouple application I/O during the application’s runtime from the PFS, pushing down the PFS one step in the storage hierarchy. This talk will discuss the impact of new memory and storage technologies on HPC and requirements and design-considerations to dynamically support the usage of node-local storage within application workflows.
