Actually, that is not quite right. From the FAQ:
“This feature currently only exists in the trunk version of the Open MPI library.”
You need to download and use the trunk version for this to work.

Subject: Re: [OMPI users] configure with cuda
I'm pretty sure cuda support was never moved to the 1.4 series. You will, however, find it in the 1.5 series. I suggest you get the latest tarball from there.

I am attempting to configure OpenMPI 1.4.3 with cuda support on a Redhat 5 box. When I try to run configure with the following command:
./configure --prefix=/opt/crc/sandbox/pwells2/openmpi/1.4.3/intel-12.0-cuda/ FC=ifort F77=ifort CXX=icpc CC=icc --with-sge --disable-dlopen --enable-static --enable-shared --disable-openib-connectx-xrc --disable-openib-rdmacm --without-openib --with-cuda=/opt/crc/cuda/4.0/cuda --with-cuda-libdir=/opt/crc/cuda/4.0/cuda/lib64
I receive the warning that '--with-cuda' and '--with-cuda-libdir' are unrecognized options. According to the FAQ these options are supported in this version of OpenMPI. I attempted the same thing with v.1.4.4 downloaded directly from open-mpi.org with similar results. Attached are the results of configure and make on v.1.4.3. Any help would be greatly appreciated.
