Subject [jira] [Commented] (HAMA-556) Graph package to support stopping the interations when the node changes are within the tolerance value as in the case of page rank
Date Fri, 04 May 2012 18:04:48 GMT

    [ https://issues.apache.org/jira/browse/HAMA-556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13268587#comment-13268587

Thomas Jungblut commented on HAMA-556:
--------------------------------------

BTW where is the activeness of a vertex? this is totally not included currently.
The Pregel API don't include this kind of convergence, this needs supervision of the graph
and can't be handled so good with it. Therefore "aggregators" should be used.

> Currently in the graph package, the iteration continues till the nodes are no longer
updated (absolutely) or the maximum number of iterations has reached. It doesn't support testing
the node changes with some tolerance and then stop the iterations as in the case of page rank.
> The above scenario might be applicable besides page rank also.
