Thanks to Brian Barrett, I was able to get through some ugly Intel compiler bugs during the configure script. I now have OMPI v1.2.5 running nicely under Mac OSX v10.5 Leopard!

However, I have a question about hostfiles. I would like to manually launch MPI jobs from my headnode, but I don't want the jobs to run on the head node. In LAM/MPI I could add a "hostname schedule=no" to the hostfile, is there an equivalent in OpenMPI? I'm sure this has come up before, but I couldn't find an answer in the archives.
