Subject: [OMPI devel] Fwd: [Open MPI Announce] Critical bug notice
From: Brad Benton (bradford.benton_at_[hidden])
Date: 2009-03-27 16:46:24


In reference to this critical bug, there are implications for the current
1.3.x release schedule that are alluded to in Jeff's message. In
particular, there are two time-critical issues at play:
  1) getting a fix for #1853 in time for inclusion for OFED-1.4.1 2)
getting in Sun's changes/CMRs in time for their next test/release cycle

Given those two time-constrained goals, we have decided to proceed as
follows:
  - Sun's desired changes are either already in the 1.3 branch, or the CMRs
have already been approved for inclusion
  - hold off non-Sun related CMRs until a fix for #1853 is available,
hopefully sometime next week
  - release this combination as 1.3.2
  - the windows functionality will then follow as a separate release: 1.3.3

I know that this, once again, pushes out the windows functionality, but I
think that this is necessary in order to get this critical fix in.

Thanks,
--Brad

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.
