[mvapich-discuss] BLCR fix for MPI problems (fwd)

[Dhabaleswar Panda]

I have received this note from Dr. Paul Hargrove (designer of BLCR). He
has released BLCR 0.6.3 and it incorporates fixes for MPI problems.

Some of you had indicated on this list earlier about experiencing
`restart' problem with MVAPICH2+BLCR on some platforms.  May I request you
to update your BLCR version to 0.6.3. Please let us know if you encounter
any further problems.

Thanks,

DK

Subject: BLCR fix for MPI problems

D.K and Josh,

  You two have forwarded to me reports from your respective MPI user
communities of problems w/ BLCR, in particular reports of corrupted
floating-point results on the x86-64 architecture.  I am pleased top let
you know that I've just released BLCR 0.6.3 to finally fix that problem.
  You should receive (may all ready have) the BLCR 0.6.3 release
announcement in a separate e-mail.  Since this fixes a serious problem
that has affected many of your users, I'd appreciate it if you could
forward the BLCR release announcement to your respective mailing lists.

Thanks,
-Paul
