For SGE:



> Are there any generic "scheduler visualization" tools out there?
> Sometimes I feel it'd be nice if I had a way to find out how my
> sceduling was performing. i.e. blocks of empty procs; how fragmented
> the job assignment was; large / small job split, utilization
> efficiency, backfill status; etc. I use openpbs (torque) + maui and it
> does have some text mode accounting reports. But sometimes they are
> hard to digest and a birds eye view might be easier via a
> visualization.
> I haven't found any toolkits yet. Of course, I could parse and plot
> myself with a bunch of sed / awk / gnuplot but I don't want to
> unnecessarily reinvent the wheel if I can avoid it. Also, I remembered
> seeing some cool visualizations (quite animated at that) at one of the
> supercomputing agencies a while ago but just can't seem to find which
> one it was now that I need it. Admittedly, some of the visualizations
> can sway more towards the "coolness" factor than actual insights but
> still it's worth a shot.
> Any pointers or scripts other Beowulfers might have are greatly
> appreciated.
