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
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?

abuse of the list. please tell me if it is but thanks to all
those who helped me.
this goes to say that the sun
