Hyunsik Choi updated HAMA-195:
------------------------------
Attachment: bsplib.uml
bsplib_uml.jpg
I'm going to show works that I have done so far. I attached two files of the
uml diagram about the bsp library. One is the image, and another is the staruml
file, an open source uml platform. I think that the functional requirements
will be well shown in the uml diagram. They have to send and receive in point
to point communication, and they have to do barrier sync.
Most of methods follow the conventional bsp library made in C. The main
difference is that our one will be based on HadoopRPC and it will use zookeeper
in order to control all of the bsp peers.
As shown in the figure, data delivery between peers is carried out by put()
method in a RPC interface BSPPeerInterface. The basic unit for transmission is
an array of bytes (i.e., byte []). When I posted the interface previously, it
was a Writable. But I modified a Writable to byte [] because it is more general
for most of applications.
In this design, each tasktracker (i.e., walker in angrapa) will have one
BSPPeer instance, and BSPPeers communicates with one another in point to point
communication. Also, they enter barrier phase or leave this phase through
zookeeper.
I want a few pieces of advice about that.
Thank you for reading.
