Subject: [OMPI users] Segfault on mpirun with OpenMPI 1.4.5rc2
From: Daniel Milroy (Daniel.Milroy_at_[hidden])
Date: 2012-01-31 14:19:57


I have built OpenMPI 1.4.5rc2 with Intel 12.1 compilers in an HPC
environment. We are running RHEL 5, kernel 2.6.18-238 with Intel Xeon
X5660 cpus. You can find my build options below. In an effort to
test the OpenMPI build, I compiled "Hello world" with an mpi_init call
in C and Fortran. Mpirun of both versions on a single node results in
a segfault. I have attached the pertinent portion of gdb's output of
the "Hello world" core dump. Submitting a parallel "Hello world" job
to torque results in segfaults across the respective nodes. However,
if I execute mpirun of C or Fortran "Hello world" following a segfault
the program will exit successfully. Additionally, if I strace mpirun
on either a single node or on multiple nodes in parallel "Hello world"
runs successfully. I am unsure how to proceed- any help would be
greatly appreciated.

Thank you in advance,

Dan Milroy
