Slowing down (but not killing) low priority jobs

[Giulio Eulisse <gi...@cern.ch>]

Hi,

we have two sets of jobs which we would like to run, some low priority 
long running jobs, and some high priority short running ones. Given we 
have enough memory to host both kind of jobs, I would like to simply 
throttle (but not kill) the CPU usage of the long running jobs in order 
to execute the high priority spike at 99% of the speed and then resume 
processing of the long running jobs as before. Is there anything which 
allows me to do that in Aurora?

Ciao,
Giulio

You may find resource oversubscription [1] helpful in this regard.
Throttling (but not killing) revocable tasks is the default Mesos
approach to handling resource pressure.
