Sorry, it's not clear to me what is happening, but perhaps this example will help. Your case sounds similar to this example: http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-tutorial.html#pres_005ftemp_005f4D-in-F90 > Is there a test program for the f90 interface with parallel IO?

You really want to build hdf5-1.8.5-patch1, and, for performance reasons, you certainly want to get the latest netCDF snapshot. I have made recent improvements which dramatically affect performance. ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz If you ask your local sysadmin, they can probably help you build HDF5, it's not hard.
