Hi All, I'm doing some tests on a small cluster with gigabit and infiniband interconnects with openmpi and I'm running into the same problem as described in the following thread: http://www.open-mpi.org/community/lists/users/2007/04/3082.php
Basically even if I run my test with: mpirun --mca btl tcp,self --prefix /share/apps/openmpi-1.3/gcc_ifort/ --machinefile machines -np 2 ./osu_latency I seem to be getting infiniband transport: # OSU MPI Latency Test v3.1.1 # Size Latency (us) 0 2.41 1 2.66 2 2.85 4 2.85 8 2.88 16 3.52 32 3.61 64 3.62 128 3.95 256 4.19 512 4.96 1024 6.31 I tried running it with --mca btl ^openib but the result is the same. I even tried, as suggested in the thread above, to remove the *openib* files from the lib/openmpi directory, but without any change. I tried with 1.2.8 and with 1.3.0 with the same results. Is there anything else I can try in order to be able to use gigabit transport? Thanks, Daniel.
