Arun C Murthy created YARN-1024: ----------------------------------- 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.* -- This message is automatically generated by JIRA.
