[os-reading] Paper for this week: Measuring interference between datacenter applications

[Venkatanathan Varadarajan <venkatv@xxxxxxxxxxx>]

Hi all,

Tomorrow, lets meet at 1 PM at 4310 CS to discuss "Measuring
Interference Between Live Datacenter Applications".

Paper link: http://arcade.cs.columbia.edu/interference-sc12.pdf.

Quick Summary:
The paper enumerates a list of challenges in measuring application 
interference in a datacenter environment. Specifically they point out 
that most of the existing solutions for measuring application 
interference make assumptions that are not practical in a datacenter 
environment like, the ability to have a learning phase in a live 
datacenter where you try out various co-scheduling application mixes and 
measure interference, etc. With the challenges/constraints imposed by a 
datacenter environment in mind, they come up with a very simple 
methodology to infer interference between running applications by 
collecting co-scheduling traces and  performance of applications 
measured using hardware counters.
