Brian,
    Here is how I do it:

./configure --prefix /opt/openmpi-1.2.4 --with-openib=/usr/local/ofed \
--without-tm CC=icc CXX=icpc F77=ifort FC=ifort \
--with-threads=posix --enable-mpi-threads

Hi all -

I have been using OpenMPI for quite a while now, and its working out great.
I was looking at the FAQ and trying to figure out how to configure OpenMPI
with infiniband. It shows how to enable IB pointing to the OFED directory.

I have infiniband built into the kernel, along with IP over IB and with the
Mellanox drivers. What would I still need to install, and how would I
configure OpenMPI to work with this?

Thanks,
  Brian_______________________________________________
