Re: [PerfSuite-users] profiling communication

[Rick K. <rk...@il...>]

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sited at NCSA are quite out-of-date.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.
