UnifyCR

UnifyCR Logo

UnifyCR is a user level file system currently under active development. An application can use node-local storage as burst buffers for shared files. UnifyCR is designed to support both checkpoint/restart, which is the most important I/O workload for HPC, and other common I/O workloads as well. With UnifyCR, applications can write to fast, scalable, node-local burst buffers as easily as they do the parallel file system.

Update

UnifyCR v0.2.0 released on February 25 (see github.com/LLNL/UnifyCR/releases).

This release includes several major enhancements developed over the past year, including integration of the Mercury RPC and Argobots lightweight threading libraries for efficient client-server communication, integration with the SLURM and LSF/CSM resource management systems, improved POSIX I/O coverage, support for the Spack HPC package manager, and numerous bug fixes from production hardening on OLCF’s Summitdev.
