The exodus library seems to be using NC_HAS_PNETCDF instead of NC_HAS_PARALLEL (i may be totally wrong about this statement), and i am wondering why.
It would be nice to be able to use NC_HAS_PARALLEL because fedora provides a parallel aware netcdf but with hdf5 and not pnetcdf, therefore VTK cannot test ioss with parallel netcdf in its CI.
https://koji.fedoraproject.org/koji/buildinfo?buildID=2659518 open-mpi build has the following segment in netcdf_meta.h
#define NC_HAS_PNETCDF 0 /*!< PnetCDF support. */
#define NC_HAS_PARALLEL4 1 /*!< parallel IO support via HDF5 */
#define NC_HAS_PARALLEL 1 /*!< parallel IO support via HDF5 and/or PnetCDF. */
