HDF5 API: Unable to delete file when using HDF5 1.12.1

[jwsblokland]

Hello,

The other day, I started using the latest version of IOR to make use of the latest HDF5 API enhancements such as setting the chunk size. When running ior in combination with HDF5 1.12.1 I got the following error from ior:

ERROR in aiori-HDF5.c (line 534): cannot delete file.

and these errors from HDF5 1.12.1

HDF5-DIAG: Error detected in HDF5 (1.12.1) MPI-process 0:
  #000: H5F.c line 767 in H5Fdelete(): unable to delete the file
    major: File accessibility
    minor: Unable to delete file

It looks like a slightly more sophisticated check has to be implemented to determine when to make use of H5Fdelete() or MPIIO_Delete().
