	I too am having problems with -mpe=mpitrace, ironically I was trying to 
use it to analyse the speed issue with nemesis. All I get in the way of 
output is :

[0] Ending MPI_Finalize
[1] Ending MPI_Finalize
[3] Ending MPI_Finalize
[2] Ending MPI_Finalize
[4] Ending MPI_Finalize

I can't downsize my code unfortunately and I get start and end messages 
for MPI calls when I compile cpi. However if this option is equivalent 
the the MPE -mpitrace option


should it also be printing out some accumulated times as well?
