Hello,
I am playing with mx__regcache_clean() in Open-MX so as to have OpenMPI
cleanup the Open-MX regcache when needed. It causes some deadlocks since
OpenMPI intercepts Open-MX' own free() calls. Is there a "safe" way to
have Open-MX free/munmap calls not invoke OpenMPI interception hooks? Or
Hi list,
We are currently experiencing deadlocks when using communicators other
than MPI_COMM_WORLD. So we made a very simple reproducer (Comm_create then
MPI_Barrier on the communicator - see end of e-mail).
We can reproduce the deadlock only with openib and with at least 8 cores
(no
what version of OpenMPI did you use? Patch #21970 should have fixed this
issue on the trunk...
Thanks

You were faster to fix the bug than I was to send my bug report :-)
So I confirm : this fixes the problem.
Thanks !

Ick; I appreciate Lisandro's quandry, but don't quite know what to do.
How about keeping libltdl fvisibility=hidden inside mpi4py?

I was kind of amazed no one else managed to run into this but it was
brought to my attention that compiling OMPI with Intel compilers and
visibility on that the MPIR_Breakpoint symbol was not being exposed. I
am assuming this is due to MPIR_Breakpoint not being ORTE or OMPI_DECLSPEC'd

I see it declared "extern" in orte/tools/orterun/debuggers.h, but not
DECLSPEC'd
FWIW: LANL uses intel compilers + totalview on a regular basis, and I
have yet to hear of an issue.

Does declspec matter for executables? (I don't recall)

It actually will work if you attach to the job or if you are not relying
on the
Do you just want to wait for the ummunotify stuff in OMPI? I'm half
done making a merged "linux" memory component (i.e., it merges the
ptmalloc2 component with the new ummunotify stuff).
It won't help for kernels <2.6.32, of course. :-)

Yeah that's another solution
Hi,
According to our TotalView person, PGI and Intel versions of OMPI
1.3.3 are not working properly. She noted that 1.2.8 and 1.3.2 work
fine.
Thanks,

As a workaround, Lisandro could just pre-seed the cache variables of the
respective configure tests that come out wrong.
./configure lt_cv_dlopen_self=yes lt_cv_dlopen_self_static=yes
HTH.
Cheers,

Hi Jeff,
Sorry about the ambiguity. I just had another conversation with our
TotalView person and the problem -seems- to be unrelated to OMPI.
Guess I jumped the gun...
Thanks,

I am trying to run open-mpi 1.3.3. between a linux box running ubuntu

I had tried before already through the .cfg and that didn't work.
