<p>Hi all,<o:p></o:p></p>
<p>
This is Ravi Kannan from CFD Research Corporation. Are there readily available
or installable commands or chunks of code to get the parallel statistics
including important ones like time spent in waiting and latency, communication
time, available memory spent in each machine etc. when solving AX=B type
problem<o:p></o:p></p>
