On Pleiades, all MPT modules starting with mpt.1.23 and earlier will be placed in a restricted access list starting on May 17, 2010, and will be removed from Pleiades on Nov. 15, 2010. Using these modules will cause jobs to randomly abort at start up with the error message:

MPI: aslistmachines('(null)') failed : protocol error - message body came out short

Please start using MPT version 1.25 (or later). If you need access to the old MPT modules, please send email to support@nas.nasa.gov.
