13.2 The pNetCDF Package

The pnetcdf package from Argonne and Northwestern can be used for parallel I/O with classic netCDF data.

For classic and 64-bit offset formats parallel I/O can be obtained with pnetcdf, the parallel netCDF package from Argonne and Northwestern.
pnetCDF is not a Unidata product, but it is well-tested and maintained. See the pNetCDF web page for more information.
pNetCDF uses MPI I/O to perform parallel I/O. It is a complete rewrite of the core C library using MPI I/O instead of POSIX.
Unfortunately the pnetCDF package implements a different API from the netCDF API, making portability with other netCDF code a problem.
