Sorry, misunderstood the question,

thanks for Pasha the right command line will be

-mca btl openib,self -mca btl_openib_of_pkey_val 0x8109 -mca
btl_openib_of_pkey_ix 1

ex.

#mpirun -np 2 -H witch2,witch3 -mca btl openib,self -mca
btl_openib_of_pkey_val 0x8001 -mca btl_openib_of_pkey_ix 1 ./mpi_p1_4_TRUNK
-t lt
LT (2) (size min max avg) 1 3.443480 3.443480 3.443480

Best regards

Lenny.
