Nothing that springs to mind
Hi,
I'm trying to use padb 3.0 to get stack traces on open-mpi / IMB1 runs.
While the job is running, I do run this, but get an error:
[ompi@hpc-hn1 ~]$ padb --show-jobs --config-option rmgr=orte
65427
[ompi@hpc-hn1 ~]$ padb --all --proc-summary --config-option rmgr=orte

I am trying to get OpenMPI built on a windows machine using Dev
Studio, and I'm not having any luck. I'm hoping someone can point me
in the right direction.
Here are the details:
Environment: Windows 7, (64 bit OS, but I’m performing a 32 bit
build), Attempting to build under Dev Studio 2010

Hey Yong,
This is very helpful ...
I have spent the morning verifying that OCTOPUS 3.2 code is
correct and that even other sections of the code that use:
MPI_IN_PLACE
are compiled without a problem. Both working and the non-working
routine properly include "use mpi_h" module which is built fr

Hi Richard,
We have reported this to Intel as a bug in 11.1.072. If I understand
it correctly you are also compiling Octopus with Intel 11.1.072. As we
have tested, Intel compilers 11.1.064 and all the 10.x, GNU, PGI,
etc., do not exhibit this issue at all. We are still waiting for words
from Inte
Hi Gijsbert
This may be more on the Torque side, but not necessarily so.
ClusterResources has decent documentation:

a non-mpi executable, e.g.:

Hi Nysal,
There is only one thread invoking MPI functions in our applications. Others
threads are related to flexlm protection routines and some self-diagnostics
routines
that don't use any MPI functions. I built a version of our application, just ot
be sure, without any other thread that the

Are there multiple threads invoking MPI functions in your application? The
openib BTL is not yet thread safe in the 1.4 release series. There have been
improvements to openib BTL thread safety in 1.5, but it is s

This is what I was wondering, it hdr->tag was expected to be null or not. I'll
soon send a valgrind output to the list, hoping this could help to locate an

Do you think that a thread race condition coul

Hi,
I am compiling a C++ program with MPI-C function calls with mpic++.
Is there effect of this on efficiency/speed of parallel program?
Thanks.
