ExaIO
The ExaIO project, led by Berkeley Lab’s Suren Byna, will deliver the Hierarchical Data Format version 5 (HDF5) library and the UnifyFS file system to efficiently address exascale storage and I/O challenges. HDF5 improvements include asynchronous I/O, caching, sub-filing, etc. The ExaIO team supports numerous ECP applications in achieving superior I/O performance with HDF5.
