parallel statistics.

[Ravi]

Hi Matt,

 

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.

 

Thanks

Ravi

Hi all,

                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


In -log_summary.

Thanks in advance
