21.3 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.
