Miklos Erdelyi updated HAMA-380:
--------------------------------
Description:
When profiling graph computations running on HAMA it turned out that huge
amount of time is spent in RPC calls.
To reduce this overhead I propose extending the GroomServer's API with a
put(BSPMessageBundle) method so that a group of messages can be transferred
from the caller to the callee at once. Also, the sync() operation should be
improved by sending messages in batches rather than one-by-one.
Using BSPMessageBundle makes it easier to add support for compression of
messages later.
