Mike,
Are you sure that you are getting the openmpi that you built and not
the one supplied w/ OS X. I use modules to make sure that I am getting
the openmpi version I build instead of the OS X suppleid version.

I’m having problems building a working version of openmpi 1.4.1/2 on
a new Apple Mac Pro (dual quad-core nehalem processors) running snow
leopard (10.6.3) with the Intel 11.1 compilers. I’ve tried the Intel
11.1.084 and 11.1.088 versions of the compilers. Everything appears
to build just fine and some mpi test programs run but whenever I run
a program with an MPI_Reduce() or MPI_Allreduce() I get a segfault
(even with np=1). I’m building openmpi with:
configure —without-xgrid —prefix=<my install path> CC=icc CXX=icpc
F77=ifort FC=ifort
When I build openmpi 1.4.1/2 with the GNU 4.3 compilers (installed
via macports) using:
configure —without-xgrid —prefix=<my install path> CC=gcc-mp-4.3
CXX=g++-mp-4.3 F77=gfortran-mp-4.3 FC=gfortran-mp-4.3
all my mpi tests (6000+) run fine. Any help would be appreciated.
Thanks,
Mike
