Mosharaf Chowdhury e898e108a3 Cleanup + refactoring... 2011-04-27 22:00:24 -07:00
Mosharaf Chowdhury 0567646180 Shuffle is also working from its own subpackage. 2011-04-27 21:11:41 -07:00
Mosharaf Chowdhury 2742de707a Removed some shuffle implementations. Remaining ones all use local files 
to write map outputs.

Timothy Hunter 5c9535228a fixed small bug when classpath has some strange formatting 2011-04-18 17:12:29 -07:00
Mosharaf Chowdhury a8f47a62b9 Renamed MaxRxPeers to MaxTxPeers to MaxTxSlots and MaxRxSlots 
respectively for clarity (most probably they were misunderstood and
misused)

Mosharaf Chowdhury b67a968b5d hasBlocks is now AtomicInteger (even though it was ok) 2011-04-02 22:03:18 -07:00
Mosharaf Chowdhury 5bf3c83b13 BroadcastSuperTracker (right now for BT) is contacted over TCP instead 
of direct procedure call.

Need to do the same for others and consolidate all broadcast mechanisms.

Mosharaf Chowdhury addd569e52 Each broadcasted variable can have different blockSize. Corresponding 
logic to adapt blockSize based on network condition is not yet
implemented.

Formatting + consolidation.

Mosharaf Chowdhury 815f3411ec Consolidated Broadcast config params. 2011-03-30 16:45:51 -07:00
Mosharaf Chowdhury a18a28b08e Removed gossip-related code that were already commented out. 
More formatting.

Mosharaf Chowdhury 73b165220d Random is the default choice; rarestFirst didn't work well in 
experiments.

Mosharaf Chowdhury 0416cc22d2 Picking peers weighted by the number of rare blocks they have. A block is rare if there are at most 2 copies in the neighborhood. Better number can be used (some function of neighborhood size) 2011-02-15 16:27:44 -08:00
Mosharaf Chowdhury cf81da9485 Optimization: Master sends out at least one copy of each block first regardless of whatever a client is asking for. Once one copy of each block is out, Master then responds to specific blocks from individual receivers. 2011-02-14 15:08:33 -08:00
Mosharaf Chowdhury 2b946fb2d1 pickBlockRarestFirst and gossips commented OUT for now. 
Problem with the rarestFirst implemention is that we are picking peers randomly first and then picking blocks from the random peer using rarestFirst. NOT the right away to do it. It should be the other way around.
Problem with gossip is that peers might end up overwriting newer information by older ones. To fix that we either have to have timestamps or must match the bitVectors before overwriting.
 2011-02-13 13:53:15 -08:00
Mosharaf Chowdhury ca2895ebb0 Fix in rarestFirst implemenation. 
If there are more than one rarest blocks, pick randomly between them (was deterministic before)
