    add the following option to your mpirun line "-mca
    btl_openib_use_message_coalescing 0".

I've tried this:

# /usr/mpi/gcc/openmpi-1.4.4/bin/mpirun -np 2
  --mca btl_openib_use_message_coalescing 0
  --mca btl_base_verbose 50
  --mca btl_openib_verbose 1
  -host cluster1,cluster2

And that's the result (which isn't different from the run without "--mca btl_openib_use_message_coalescing 0"):


I thank you!
