[MPICH] MPICH2+MPE on windows

[James S Perrin]

Hi,
	This is a follow up to an earlier thread (Status of MPE2 on Windows) where it 
was stated that to run an mpi job with profiling you can use the (undocumented) 
-log  to mpiexec (smpd only). This didn't work for my master/slave job until I 
realised -log isn't a global option and has to be specified for each group of 
processes.

	However I noticed while digging around in the source code -log sets the wrapper 
dll to "mpe" whereas the suggested default is "mpich2mpe" 
(src/util/multichannel/mpi.c). I was wondering is there any difference, I didn't 
notice any when passing "-env MPI_WRAP_DLL_NAME mpich2mped" to mpiexec?

Regards
James
