[netCDF #NBR-155156]: Installation of parallel HDF5

Howdy David,

You are using netCDF 3.6.3, which is several years old, and contains no 
parallel I/O features. It's purely sequential I/O.

If you would like parallel I/O you need to get the latest version of netCDF. In 
fact, I suggest you get the latest daily snapshot and try that:
ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz

Build it according to instructions here:
http://www.unidata.ucar.edu/software/netcdf/docs_snapshot/netcdf-install.html#Quick-Instructions

Parallel I/O is available for netCDF-4/HDF5 files via HDF5, but HDF5 must be 
built with --enable-parallel. Parallel I/O on classic and 64-bit offset files 
is also available via the parallel-netcdf (formerly pnetcdf) library. It must 
be installed before netCDF is built.

Good luck,

Ed
