Charm++ parallel programming system

[Pritish Jetley <pjetley2 AT uiuc.edu>]

There is a pingpong test in tests/charm++/pingpong. This program calculates round-trip latency in various scenarios using small messages. You could change the payload size therein to get communication times for different message sizes.

Hi

I have successfully installed Charm++ on our cluster (SGI Altix ICE). I have both the net- and mpi- versions of Charm++ built and want to compare the communication performance on both versions. The MPI version is compiled against SGI's MPT library MPI implementation which is supposed to be fast on the SGI cluster.

How can one compare the communication performance ? Is there a ready made program in Charm++ distribution ?

Regards,
