2.   if you are using Open MPI 1.3 you dont have to use mpi_leave_pinned 1 , since it's a default value
And if you're using "-mca btl self,sm" on a single node, I think mpi_leave_pinned is immaterial (since it's for openib).

Here are muy options with OpenMPI:

mpirun -n 8 --machinefile hf --mca rmaps_rank_file_path rankfile --mca coll_sm_info_num_procs 8 --mca btl self,sm -mca mpi_leave_pinned 1 ./xhpl_ompi

Here is my rankfile:

at rankfile
rank 0=i02n05 slot=0
rank 1=i02n05 slot=1
rank 2=i02n05 slot=2
rank 3=i02n05 slot=3
rank 4=i02n05 slot=4
rank 5=i02n05 slot=5
rank 6=i02n05 slot=6
rank 7=i02n05 slot=7
