Monitoring StarCluster / Sun Grid Engine Cluster Performance

Question

I am a bit new to using StarCluster and SGE. I was wondering what the best practice is for monitoring "Cluster Performance", that is, to determine how many of a certain job the cluster can run in some unit of time. I am familiar with qstat command but that just shows the status of each job. I guess my use case is to submit X jobs and to know how long it takes for all X to complete. Is there an easy out-of-the-box way to do this or must I write a scipt to do it?

Right now I am using Ubuntu 12.04 for each instance.

Thanks Much!

Answer 1

A simple bash script like this one + a time command should suffice then.

lines=999
while [ $lines -ne 0 ]; do
    sleep 1;
    lines=`qstat -u "*" | wc -l`;
    done;

This script will loop as long as the queue is not empty. If you call your script "queue_watch.sh", then start you jobs and then run the command

time bash queue_watch.sh

And that should do it.
