[PerfSuite-users] profiling communication

[George M. <ge...@ma...>]

Dear all,

I would like to ask if it is possible to profile the communication of a 
fortran program. I have compiled it with -lpspmpi, and I am not sure how 
I can get the xml files about communication, I get only about hardware 
counters. I would be grateful for any help. Is it possible to profile 
the communication of the application automatically?

Best regards,
George

Communication of what kind?  There are many tools for this type of
thing.  You might look at TAU since it supports MPI, Pthreads, OpenMP,
Fortran, C, C++, etc. as well as low-level instrumentation with PAPI.
There is also Scalasca, but I haven't tried it yet.

If you mean communication below MPI, such as IB verbs, I don't know
any tool for that.

George,

Jeff is right - there are a number of different ways of profiling MPI 
communication.  I'm afraid the issue regarding PSPMPI, which was a 
development project within PerfSuite several years ago is that the pages 
sited at NCSA are quite out-of-date.  PSPMPI was never released because 
other tools/libraries were developed elsewhere that fill the need quite 
nicely, so duplication/reinventing the wheel didn't make sense.  Sorry 
for the confusion.

In addition to the tools mentioned below, I have found MPIP (LLNL/ORNL) 
to be quite useful and very low overhead.  There is information located 
here: http://mpip.sourceforge.net/

TAU and Scalasca are both participating in the active POINT project [ 
http://nic.uoregon.edu/point ], as is PerfSuite.

Dear all,

thanks for your answers, I was wondering mainly for profiling only with 
this tool both hardware counters and MPI communication but ok you 
answered my question, I was just confused by the documentation.

Thanks a lot,
Best regards,
George
