  class Mpifileutils(Package):
      """mpiFileUtils is a suite of MPI-based tools to manage large datasets,
         which may vary from large directory trees to large files.
         High-performance computing users often generate large datasets with
         parallel applications that run with many processes (millions in some
         cases). However those users are then stuck with single-process tools
         like cp and rm to manage their datasets. This suite provides
         MPI-based tools to handle typical jobs like copy, remove, and compare
         for such datasets, providing speedups of up to 20-30x."""
