Subject: [Open MPI Announce] Critical bug notice
From: Jeff Squyres (jsquyres_at_[hidden])
Date: 2009-03-27 14:34:46


The Open MPI team has uncovered a serious bug in Open MPI v1.3.0 and
v1.3.1: when running on OpenFabrics-based networks, silent data
corruption is possible in some cases. There are two workarounds to
avoid the issue -- please see the bug ticket that has been opened
about this issue for further details:

     https://svn.open-mpi.org/trac/ompi/ticket/1853

We strongly encourage all users who are using Open MPI v1.3.0 and/or
v1.3.1 on OpenFabrics-based networks to read this ticket and use one
of the workarounds described there.

The Open MPI team is working on a fix; it will be included in the
v1.3.2 release. Updates will be posted to the ticket.
