Subject [jira] [Commented] (HAMA-519) [GSoC 2012] Add simple latency and bandwidth measuring tool
Date Tue, 03 Apr 2012 12:08:24 GMT

    [ https://issues.apache.org/jira/browse/HAMA-519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13245166#comment-13245166

Thomas Jungblut commented on HAMA-519:
--------------------------------------

Besides that I have never seen a task that is much more effort than 20h, we want to use the
information for active scheduling. So it is not only about writing a BSP job that can be used
to measure these stats. It would be cool if we can integrate this into our metrics system
and display the result on our web frontend.

bq. Now do you think the network status information can be used to determine the number of
Task processors per node?

Tasks / node is much more sophisticated than just measuring bandwidth. Consider RAM limitations
or CPU load as well as IOWait for IO heavy tasks.

be added contrib.
