<p class=MsoNormal>log_summary does give information like time for barrier, zero
size MPI_send. However interesting statistics like total latency time,
computation/communication time ratio etc. This is needed by me to study the
effect of partitions and BCs.<o:p></o:p></p>

<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>
