> We need to clearly define the meaning of a virtual core unambiguously so that it's easy
to migrate applications between clusters.
> For e.g. here is Amazon EC2 definition of ECU: http://aws.amazon.com/ec2/faqs/#What_is_an_EC2_Compute_Unit_and_why_did_you_introduce_it
> Essentially we need to clearly define a YARN Virtual Core (YVC).
> Equivalently, we can use ECU itself: *One EC2 Compute Unit provides the equivalent CPU
capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor.*
