How to profile memory usage and performances of an openMPI program in C

Question

Hi,

I'm looking for a way to profile my openMPI program in C, i'm using openMPI 1.3 with Linux Ubuntu 9.10 and my programs are run under a Intel Duo T1600.

what I want in profile is cache-misses, memory usage and execution time in any part of the program.

thanks for reply

Answer 1

Have a look at gprof and at Intel's VTune. Valgrind with the cachegrind tool could be useful, too.

Answer 2

For Linux I recommend Zoom for this kind of profiling. You can get a free 30 day evaluation in order to try it out.

Answer 3

Hi,

I finally found graphical tools for mpi profilling
