Subject [jira] [Commented] (HAMA-367) Runtime Compression of BSP Messages to Improve the Performance

Thomas Jungblut commented on HAMA-367:
--------------------------------------

Hey Ashish, as already mentioned on the mailing list. If you are in local mode, you'll never
reach this piece of code.
I can give you an advice to use the MiniBSPCluster in the test package. You have to pull it
out of the JUnit test logic, but after setting it up you can submit your jobs quite easily
and debug.

Have a try. If you need help, don't hesitate to write to the mailing list.

> As you know, the exchanging data between processes, is a core part of whole performance
in Bulk Synchronous Parallel.
> In this research, we investigate BSP message data compression in the context of large-scale
distributed message-passing systems to reduce the communication time of individual messages
and to improve the bandwidth of the overall system.
