Re: Dynamically add packages on the server
I would imagine it would be possible to use ksysgaurd to check.
A couple of ways to do this come to mind:
1)You could try running 2 smaller, separate clusters simultaneously, an monitor your network usage (obviously impractical)
2)You could try taking screen shots of your network usage under different scenarios (more/fewer nodes, running short/long jobs/idle, compare plain fs to squashfs, ect) obviously you would have to reboot for each fs you test.
3)And finally it may be possible to write some script to collect data to a log file, and display some measurement (average usage, median usage, modal usage, or some similar setup) Not sure about this last one, but if possible it would likely be most useful coupled with the previous setup.
I think it would be rather interesting to see the results.
