- async-multiple and PVFS2 has been a long-standing irritant. Thanks
  for confirming it's still broken.

- atomicity is a known failure for PVFS2: that file system cannot
  support MPI-IO atomic mode

- misc, fmisc: see atomicity

- shared_fp, ordered_fp: known problem (unsupported mode)

So I would say your PVFS and MPI installation is looking great.  The
next step is to try out a real application.
