Web Reference: The Parallel IO libraries (PIO) are high-level parallel I/O C and Fortran libraries for applications that need to do netCDF I/O from large numbers of processors on a HPC system. PIO provides a netCDF-like API, and allows users to designate some subset of processors to perform IO. The Parallel IO libraries (PIO) are high-level parallel I/O C and Fortran libraries for structured grid applications. PIO provides a netCDF-like API, and allows users to designate some subset of processors to perform IO. PISM supports several parallel I/O approaches that take advantage of parallel NetCDF and PnetCDF. The administrators of your HPC system should be able to help you install these libraries, but it may be easier to install them in the “home” directory instead.
