[mpich-discuss] MPE tracing

[Georges Markomanolis]

Thank you all for your answers,

I used clog2print because I wanted to see only the traces, not the 
visualization as I need to convert the MPE traces into another format 
that I need. Moreover I changed the output of the tracing library in 
order to have the format that I mentioned and it seems to work very 
nice. One more question. Is it possible to have a selective 
instrumentation with the tracing library? I think something similar with 
the customized logging but for tracing, I just need to know which MPI 
calls are executed by a block of code.

Thanks a lot,
Best regards,
Georges
