Having a user who requires some of the features of gfortran in 4.1.2, I recently began building a new image. The issue is that "-mca btl gm" fails while "-mca mtl gm" works. I have not yet done any benchmarking, as I was wondering if the move to mtl is part of the upgrade. Below are the packages I rebuilt.
Kernel 2.6.16.27 -> 2.6.20.1 Gcc 4.1.1 -> 4.1.2 GM Drivers 2.0.26 -> 2.0.26 (with patches for newer kernels) OpenMPI 1.1.4 -> 1.2 The following works as expected: /usr/local/ompi-gnu/bin/mpirun -np 4 -mca mtl gm --host node84,node83 ./xhpl The following fails: /usr/local/ompi-gnu/bin/mpirun -np 4 -mca btl gm --host node84,node83 ./xhpl I've attached gziped files as suggested on the "Getting Help" section of the website and the output from the failed mpirun. Both nodes are known good Myrinet nodes, using FMA to map.
