java.lang.Object
  org.javaseis.tests.CommunicationBenchmark

public class CommunicationBenchmark
extends java.lang.Object

Communication benchmark to measure "all to all" style operations. The main program takes two arguments for buffer size and iteration count. The program then calls IParallelContext.bcast, shift, and ttran with the given buffer size and iteration count.

Results are printed as MegaBytes (1024*1024 bytes) per second on a per node and total basis.

public static void main(java.lang.String[] args)
                 throws MPIException

Run communication benchmark.

Parameters:

args - argument string from command line Program arguments:

 -size size[m][k] : size of the buffer used in 32 bit words. The suffix
                    'm' indicates the size is in MegaBytes,
                    'k' indicates size in 'KiloBytes'
 -count count     : iteration count for the test.
 

Throws:

MPIException
