  == Communication and Synchronization Process ==
  
- Each BSPTask has a set of private outgoing and incoming queues. So, 
+ Each BSP task has a set of Outgoing Message Manager and Incoming Queue.
  
+ Outgoing Message Manager collects the message to be sent, serializes it, compresses it and
puts it in a bundles. At barrier synchronization phase, each BSP task exchanges the bundles,
deserializes it, decompresses it and puts it into the Incoming Queue.
-  1. Each task puts the message to be sent into message bundle asynchronously.
-  2. At sync() phase, sends them to destination Task. The received bundles from others goes
into incoming (local) queue after unbundling.
