Summary     : MPICH Jumpshot - Graphical visualization Tool
Description :
Jumpshot is a Graphical visualization Tool for MPICH written using
Java Version 1.1 JDK. It is used to study binary logfiles of 'clog'
format.

Note that there may be problems running under some versions of Linux Java.
I have found it works well on jdk-sn-1.1.6.
