13.3 Parallel I/O in NetCDF-4
NetCDF-4 exposes the parallel I/O features of HDF5.
- HDF5 provides easy-to-use parallel I/O feature.
- Parallel I/O allows n processes on m processors to read and write
netCDF data, where n and m are integers usually < 10K.
- Parallel I/O requires an implementation of MPI2. The MPICH2
package is one example of an MPI2 library. Supercomputers often have
a proprietary implementation of MPI2.
