How to benchmark communication cost in a beowulf system

[Thomas Zheng]

Hi all,

I am evaluating a beowulf system for my application.  The first thing I 
want to check is the communication cost my application would incur in a 
100-baseT interconnect.  I am wondering if there's some programs out there 
to help me do this or any suggestion on how to do this is welcomed.

Thanks.

Regards,
