Technical Overview

PnetCDF is a high-performance parallel I/O library for accessing files in format compatibility with Unidata's NetCDF, specifically the formats of CDF-1, 2, and 5. The CDF-5 file format, an extension of CDF-2, supports unsigned data types and uses 64-bit integers to allow users to define large dimensions, attributes, and variables (> 2B array elements).

This library is required by cam-se (homme) benchmark from the LLNL CORAL suite. It should be used with MPI workloads (the ones build with mpicc, mpicxx, mpif90, etc.), and for that reason it should be provided for all combinations of compiler/MPI families.

The package provides static library libpnetcdf.a. Since exported functions contain calls to MPI runtime library, all potential users should use mpi* wrappers (mpicc, mpifort, etc.) when building code depending on this library.

A pull request with ready to use specfile and imported test cases was already issued for this package and waits for acceptance.

Just documenting that @pawosm-arm has builds for this in his home project at:

https://build.openhpc.community/package/show/home:pawel:branches:OpenHPC:1.3:Update1:Factory/pnetcdf

The associate build collateral is available in PR #441
