[gmx-users] Alert for Open MPI bug v1.3.0 and v1.3.1

[chris.neale at utoronto.ca]

Hello gromacs users,

Since Open MPI is commonly used with gromacs, I thought that I would  
cross post this important notification that I received via the Open  
MPI mailing list.

### Quoting:

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.
