Subject [jira] Commented: (HAMA-241) send method in BSPPeer.java should store messages to local storage temporarily.
Date Thu, 03 Jun 2010 07:07:09 GMT

    [ https://issues.apache.org/jira/browse/HAMA-241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12874985#action_12874985
] 

Edward J. Yoon commented on HAMA-241:
-------------------------------------

1. In send() mehod, intermediate data should be materialized locally.
2. GroomServer should manage the intermediate data generated during superstep computations.

Then, intermediate data can be used for recovery fails.

> Because of data size and fault tolerance, each BSP peer should store messages into its
local storage at each super step.
