Hi Ralph and Geffroy I've been following this thread with a lot of interest. Setting processor affinity and pin the processes to cores was next on my "TODO" list, and I just started it. I tried to use three different versions of rankfile, with OpenMPI 1.3.1 on a dual-socket quad-core Opteron mac

[OMPI users] How do I compile OpenMPI in Xcode 3.1

Admittedly, I don't use Xcode to build Open MPI either. You can just compile Open MPI from the command line and install everything in /usr/local/. Make sure that gfortran is set in your path and you should just be able to do a './configure --prefix=/usr/local' After the installation, just m

Re: [OMPI users] How do I compile OpenMPI in Xcode 3.1

Open MPI comes pre-installed in Leopard; as Warner noted, since Leopard doesn't ship with a Fortran compiler, the Open MPI that Apple ships has non-functional mpif77 and mpif90 wrapper compilers. So the Open MPI that you installed manually will use your Fortran compilers, and therefore will

Have you installed a Fortran compiler? Mac OS X's developer tools do not come with a Fortran compiler, so you'll need to install one if you haven't already done so. I routinely use the Intel IFORT compilers with success. However, I hear many good things about the gfortran compilers on Mac O
