Subject [jira] [Commented] (YARN-1024) Define a virtual core unambigiously
Date Mon, 26 Aug 2013 17:23:54 GMT

    [ https://issues.apache.org/jira/browse/YARN-1024?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13750270#comment-13750270

Chris Riccomini commented on YARN-1024:
---------------------------------------

Realized I'm conflating ECU with AWS machine instances. I retract the whole last paragraph.

> 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.*
