Look at your output from mpicc --showme. It indicates that the OMPI libs were put in the lib64 directory, not lib.

Something looks fishy about your numbers. The first two sets of
numbers look the same and the last set do look better for the most
part. Your mpirun command line looks weird to me with the "-mca
orte_base_help_aggregate btl,openib,self," did something
get chopped off with the text copy? You should have had a "-mca btl
openib,self". Can you do a run with "-mca btl tcp,self", it should
be slower.
I really wouldn't have expected another compiler over IB to be that
dramatically lower performing.

According to the last run, did using the sun compilers (update 1
) result in higher performance with sunct?

this goes to say that the sun
