[mpich-discuss] MPI software profiling

[Marc]

Anthony gave you the relevant links. But here's more details.

If you want to use TAU along with jumpshot, you will have to compile
yourself in order: slog2sdk, PDT and TAU itself. Also, jumpshot is a
java application and needs the jdk and jre packages.

As described in
http://www.mcs.anl.gov/research/projects/perfvis/software/viewers/index.htm, jumpshot shows you in a colorful way the time taken by Mpich functions and many others things, like arrows indicating message passing which is pretty useful to analyse race conditions and deadlocks. To use TAU, you will have to compile you code with a script, run your application with mpirun, merge the trace files, then convert the resulting file in the slog2 format which can be finally opened with jumpshot.

Read the documentation for TAU in the users guide to install it with the
right options to make it work with slog2sdk. Jumpshot documentation is
given in the link above.

Hope this helps,

Marc
