unifyfs (spack): User level file system that enables applications to use node-local storage as burst buffers for shared files. Supports scalable and efficient aggregation of I/O bandwidth from burst buffers while having the same life cycle as a batch-submitted job. UnifyFS is designed to support common I/O workloads, including checkpoint/restart. While primarily designed for N-N write/read, UnifyFS compliments its functionality with the support for N-1 write/read.
