Here we see an Xab window showing four PVM tasks and what they are up to. For example, the first task, (cholhost, 0) is running on a machine named betty. This task is doing a rcv for a message with type 16003.
Xab3 for PVM Version 3 is available ftp. The source and some documentation, including man papges, are included int the xab3 tar file. You can also find a paper about Xab in that directory. Click here to view the postscript .
Xab3 has a lot of nice features. For instance you can adjust the level of monitoring as a program is running. We also have converters to ParaGraph and Pablo if you want to do more visualization on the tracefiles.
