Subject: [OMPI users] Problem using VampirTrace
From: Thomas Ropars (tropars_at_[hidden])

Hi all,

I'm trying to use VampirTrace.
I'm working with r19234 of svn trunk.

When I try to run a simple application with 4 processes on the same
computer, it works well.
But if try to use the same application with the 4 processes executed on
4 different computers, I never get the .otf file.

I've tried to run with VT_VERBOSE=yes, and I get the following trace:
