How do we take this technique to the next step where we can 
consolidate short running jobs as well?  Did you face any difficulty 
biasing the CPU for short running jobs?

are you sure your measurement tasks do not impact the measurement 
workload? If you use something like 'top' then try running it reniced to 
+19. (or perhaps even bound to a particular CPU, say #3, to make its 
impact isolated)

Hi Ingo,

I will watch this during the experiments.  I have been using klog
application to dump relayfs data.  I did run powertop and top as well,
I will bind them to certain CPUs and isolate their impact.

I believe the margin of error would be less since all the measurement
tasks sleep for long duration.

Thanks,
Vaidy
