HDF5 VOL Status Report – Exascale Computing Project

As part of our work with the Exascale Computing Project (ECP), Scot Breitenfeld, Hyo-Kyung Lee, and Larry Knox prepared this status report on the HDF5 VOL. This report provides an overview of the HDF5 VOL connectors created for the ECP. Building and testing of VOLs were added to Spack and are discussed in Section 2. Finally, Sections 3-7 further investigated the async-vol and the log-vol with applications. The adios-vol was not tested for this group of applications since it does not support hyperslab selections. Section 8 discusses the next steps in VOL connectors evaluation. Section 9 documents the status of VOL connectors testing.
