Subject [jira] [Commented] (HAMA-460) Website update for 0.4 release
Date Tue, 20 Dec 2011 07:51:31 GMT

    [ https://issues.apache.org/jira/browse/HAMA-460?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13173004#comment-13173004

Edward J. Yoon commented on HAMA-460:

Just my note:

Why BSP?

Today, many practical large processing applications requires a good scalability, a high compatibility
with existing data systems e.g., HDFS, HBase, and a communication capability which allows
to exchange information using message-passing paradigm beyond MapReduce.

Here, Bulk Synchronous Parallel (BSP) model fills the bill nicely and besides, it has several
main advantages over MPI:

 - Provides a simple and small API
 - Enables to perform better than MPI for communication-intensive applications
 - Guarantees impossibility of deadlocks or collisions in the communication mechanisms, and
 - The possibility to evaluate the computational cost of an algorithm
