Hi Ralph,
I tried to build 1.4.3.a1r23542 (08/02/2010) with
./configure --prefix="/g/software/openmpi-1.4.3a1r23542/gcc-4.1.2 2"
--enable-cxx-exceptions CFLAGS="-O2" CXXFLAGS="-O2" FFLAGS="-O2"
FCFLAGS="-O2"

It seems that using '--loadbalance' also crashes mpirun.

We have it fixed in the 1.4.x nightly tarballs; can you give it a whirl and see
if that fixes your problem?

Hello OMPI:
We have installed OMPI V1.4.2 on a Nehalem cluster running CentOS5.4.
OMPI was built uisng Intel compilers 11.1.072. I am attaching the
configuration log and output from ompi_info -a.
The problem we are encountering is that whenever we use option
'-npernode N' in the mpirun
