parallel hdf with xdmf

hi all,
      i might be in the wrong channel to ask this question. just in case you
might have the answer to the question, please allow me to ask whether the
parallel hdf works with xdmf format from http://www.xdmf.org . Besides is
parallel hdf supported on ranger(AMD) machine at Texas university and Cray
supercomputer(jaguar/kraken)?
thanks
