-----------------------------------
Summary: Define a virtual core unambigiously
Key: YARN-1024
URL: https://issues.apache.org/jira/browse/YARN-1024
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Arun C Murthy
Assignee: Arun C Murthy
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
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.*
