Hi Dave,
I looked through the INSTALL, VERSION, NEWS, and README files in the
1.5.4 openmpi tarball but didn't see what you were referring to. Are you
suggesting that I launch mpirun similar to this?
mpirun -mca plm ^rshd ...?
What I meant by "the same parallel environment setup" was that

Hi Gus,
I am building using the cray wrappers over the PGI compilers, which
gives the errors. I tried building without the cray wrappers, but then
it does not run in parallel on the XE6 system I am using. I am going
to try the latest nightly build.
Abhinav.

To be clear my RHEL 5 and RHEL 6 nodes are part of the same cluster. In
the RHEL 5 case qrsh -inherit gets called via mpirun. In the RHEL 6 case
/usr/bin/ssh gets called directly from mpirun. The cluster setup looks like:

Hi Gus,
I have not added any flags that include static, but when I do a
verbose compilation output for the point where error occurs, I see
that there are some -Bstatic flags. I tried to manually remove the

Yes, I have tried that. The clean up does not help to make sm btl

Thanks!
I'll see that this gets into 1.6.

When you receive that callback the MPI has ben put in a quiescent state. As
such it does not allow MPI communication until the checkpoint is completely
finished. So you cannot call barrier in the checkpoint callback. Since Open
MPI did doing a coordinated checkpoint, you can assume that all process

If you compiled Open MPI in a computer with IB hardware,
then copied the installation tree to another machine,
or if you installed from an RPM or other package generated in a

machine where it is running does not

Hi Abhinav
Did you add to your compiler flags -Bstatic [or perhaps -static],
or any optimization flags that may include -Bstatic/-static?
Check also the compiler configuration, and any possible user customization
[~/.mypggcc and friends] to see if -Bstatic is there, maybe inadvertently, and

It is possible to have the OpenFabrics drivers loaded in your kernel, even if
you have no OpenFabrics-based devices in your hardware.
You probably just want to unload those drivers, and then Open MPI should not

There are many MPI tutorials available. A very good one that I have referred

There's 2 levels to the tutorial: introduction and intermediate.
