Subject [jira] [Created] (HAMA-413) Remove limitation on the number of tasks
Date Wed, 13 Jul 2011 00:44:59 GMT
Remove limitation on the number of tasks
----------------------------------------

                 Key: HAMA-413
                 URL: https://issues.apache.org/jira/browse/HAMA-413
             Project: Hama
          Issue Type: Sub-task
          Components: bsp
    Affects Versions: 0.3.0
            Reporter: Edward J. Yoon
             Fix For: 0.4.0


By HAMA-410 patch, BSPPeer object will be constructed at child process. Now we can just remove
limitation on the number of tasks.

Here's TODO list:

1. The number of tasks per groom should be configurable e.g., 'bsp.local.tasks.maximum'.
2. The 'totalTaskCapacity' should be calculated at BSPMaster.getClusterStatus().
3. When scheduling tasks, consider how to allocate them.
4. Each BSPPeer should know all created peers of Hama cluster by job. It can be listed based
on actions of GroomServer.
5. In examples, 'cluster.getGroomServers()' can be changed to 'cluster.getMaxTasks()'.
