I/O

ADIOS2: An adaptable framework for HPC I/O supporting files, in situ, and in transit data movement. ADIOS2 also generates an HDF5 VOL Adapter.
HDF5: A data model, library, and file format for storing and managing data.
- CUDA support (where applicable) is provided by the HDF5 GPUDirect Storage VFD. Refer to the documentation for more information on enabling GDS VFD for your application. The SDK will install the package and populate HDF5_PLUGIN_PATH (only).
- HDF5 VOL plugins will be installed with HDF5_PLUGIN_PATH populated:
  - ADIOS2: when ecp-data-vis-sdk +adios2 +hdf5 is installed, the ADIOS2 VOL is installed (by the adios2 package).
  - hdf5-vol-cache, hdf5-vol-async, and hdf5-vol-log are installed** when ecp-data-vis-sdk +hdf5 ^hdf5@1.14: is installed. (6)
  - hdf5-vol-daos is a VOL adapter used for direct interfacing with the Distributed Asynchronous Object Storage (DAOS) system, bypassing both MPI I/O and POSIX for efficient and scalable I/O. This VOL adapter is currently being tested on Pre-Aurora systems with DAOS support.
PNetCDF: A high-performance parallel I/O library for accessing Unidata’s NetCDF, files in classic formats, specifically the formats of CDF-1, 2, and 5.
