---------------------------------------------------------------
Let's summarize a bit:
- Input and InputFormat are managed the same way as it is in Hadoop.
- Input send as initial messages
- Coordination between client and BSP
- Input has random read feature
*Input and InputFormat are managed the same way as it is in Hadoop.*
& *Input send as initial messages*
This sounds clear, how do we split the data? And how does this going to be send
to the tasks as initial messages?
*Coordination between client and BSP*
Not a part of the I/O System, is it? Sounds like a more general synchronization
between the BSPClient and our BSPMaster.
*Input has random read feature*
This is great, but a lot of work? / Additional feature.
What are your ideas Edward?
