11.14 Parallel I/O
Parallel I/O exploits parallel file systems on high-performance
computing platforms.
- NetCDF-4 uses HDF5's support for parallel I/O built on top of MPI-IO.
- Vendors typically provide an optimized MPI-IO layer on top of their
parallel file system implementation.
- Special
create and open calls are used to open a file for parallel data
access.
- An example of use of netCDF-4 and MPI for creating a file for
parallel access is available in the netCDF User's Guide.
