[MPICH] newbie: how to start slogging?

[Harry Mangalam]

Hi All,
We've been working on some MPI'ed apps for a while and would like to start the 
slogging process so we can use the jumpstart family to profile and debug some 
of the itchier part of them.

I've installed Zach's debs (including the mpe deb) and the MPI'ed apps run 
well even on my little thinkpad.

I've modified the makefile to link with the relevant libs (-lmpe -llmpe -ltmpe 
-lampe) and the build process appears to work, but I can't figure out how to 
signal the apps to dump the slogs.  

I've spent the greater part of a day reading docs and trying various hacks but 
can't figure this out.
It appears that it should be automatic - but the apps don't leave a slog trail 
anywhere I've been able to tell.  Is there a switch in the build procedure or 
one to pass to the app itself that turns on the generation of the slogs?
