I have not tried the bundled version yet but the standalone beta
version worked well for me and was very easy to use. Running
the Message Checker regularly on all the crucial tests before 
releasing your software seems like a good idea.
Thanks God the wait is over. I thought the product was ready
almost two years ago.

For dealing with parallel logic (or at least one level of it) Intel has 
an interesing-looking tool for sanity-checking MPI communication called 
the "Intel Message Checker". It used to be available as a stand-alone 
beta version but now seems to be bundled with the Intel Trace Analyzer 
suite.

I haven't experimented with it yet but the feature set looks promising 
for catching hard-to-find errors in parallelization. Has anyone tried it 
and does it work as advertised?
