Edward J. Yoon commented on HAMA-258:
-------------------------------------
{code}
public void bsp(BSPPeerProtocol bspPeer) throws Exception {
// Send initial messages to each peers.
Table input = table.open(“graph”);
int i = 0;
for (String peerName : cluster.getActiveGroomNames().values()) {
Map<K, V> subSet = input.getSubset(i);
for(Map.Entry<K, V> entry : subSet.entrySet()) {
...
bspPeer.send(peerName, new BSPMessage(Tag, Data));
}
i++;
}
bspPeer.sync();
…..
}
{code}
This is very rough idea. I think, we can broadcast initial messages to each
peers like above code.
Unlike MapReduce system, we can assign the data to each tasks flexibly.
