just tried -mpe=mpitrace with cpi.c in 
<mpich2_108_install_dir>/share/examples_logging,
I see trace output appears on my terminal.
What program are you trying this ?
If the program is small, can you send me the
code so I can check/confirm if MPE has any bug ?

In terms of Valgrind, did you configure mpich2 with --enable-g=meminit
which reduces some valgrind warnings...?  See "configure --help"
for more info.
