<h1>Communication</h1>
+<hr />
<p>Different messaging libraries has different benefits and drawbacks. For
instance, MPI provides fast message passing between GPUs (using GPUDirect), but
does not support fault-tolerance well. On the contrary, systems using ZeroMQ
can be fault-tolerant, but does not support GPUDirect. The AllReduce function
of MPI is also missing in ZeroMQ which is efficient for data aggregation for
distributed training. In Singa, we provide general messaging APIs for
communication between threads within a process and across processes, and let
users choose the underlying implementation (MPI or ZeroMQ) that meets their
requirements.</p>
<p>Singa’s messaging library consists of two components, namely the
message, and the socket to send and receive messages. <b>Socket</b> refers to a
Singa defined data structure instead of the Linux Socket. We will introduce the
two components in detail with the following figure as an example
architecture.</p>

Each process consists of one main thread running the stub and multiple

Our previous design used MPI for communication between Singa processes. But MPI
is a poor choice when it comes to fault-tolerance, because failure at one node
brings down the entire MPI cluster. ZeroMQ, on the other hand, is fault
tolerant in the sense that one node failure does not affect the other nodes.
ZeroMQ consists of several basic communication patterns that can be easily
combined to create more complex network topologies.</p>
<p><img src="../images/msg-flow.png" style="width: 550px" alt="" />
<p><b> Fig.3 - Messages flow for ZeroMQ</b></p>
<p>The communication APIs of Singa are similar to the DEALER-ROUTER pattern of
ZeroMQ. Hence we can easily implement the Dealer socket using ZeroMQ’s
DEALER socket, and Router socket using ZeroMQ’s ROUTER socket. The
intra-process can be implemented using ZeroMQ’s inproc transport, and
the inter-process can be implemented using the tcp transport (To exploit the
Infiniband, we can use the sdp transport). Fig.3 shows the message flow using
ZeroMQ as the underlying implementation. The messages sent from dealers has two
frames for the message header, and one or more frames for the message content.
The messages sent from routers have another frame for the identifier of the
destination dealer.</p>
<p>Besides the DEALER-ROUTER pattern, we may also implement the Dealer socket
and Router socket using other ZeroMQ patterns. To be continued.</p></div>
<div class="section">
-<h4><a name="MPI"></a>MPI</h4>

<p>Since MPI does not provide intra-process communication, we have to
implement it inside the Router and Dealer socket. A simple solution is to
allocate one message queue for each socket. Messages sent to one socket is
inserted into the queue of that socket. We create a SafeQueue class to ensure
the consistency of the queue. All queues are created by the main thread and
passed to all sockets’ constructor via <i>args</i>.</p>

communication.</p>
-<p>MPI’s AllReduce function is efficient for data aggregation in
distributed training. For example, <a class="externalLink"

-<p>Each server has a DEALER socket to communicate with the stub in the main
thread via an <i>in-proc</i> socket. It receives requests issued from workers
and other servers, and forwarded by the ROUTER of the stub. Since the requests
are forwarded by the stub, we can make the location of workers transparent to
server threads. The stub records the locations of workers and servers.</p>

href="http://singa.incubator.apache.org{%";>http://singa.incubator.apache.org{%</a>
post_url /docs/2015-03-20-parameter-management %}) for parameter management,
some requests may not be processed immediately but have to be re-queued. For
instance, the Get request cannot be processed if the requested parameter is not
available, i.e., the parameter has not been put into the server’s
ParamShard. The re-queueing operation is implemented sendings the messages to
the ROUTER socket of the stub which treats the message as a newly arrived
request and queues it for processing.</p></div>
-<div class="section">
-<h4><a name="Worker_socket"></a>Worker socket</h4>
-<p>Each worker thread has a DEALER socket to communicate with the stub in the
main thread via an <i>in-proc</i> socket. It sends (Get/Update) requests to the
ROUTER in the stub which forwards the request to (local or remote) processes.
In case of the partition of ParamShard of worker side, it may also transfer
data with other workers via the DEALER socket. Again, the location of the other
side (a server or worker) of the communication is transparent to the worker.
The stub handles the addressing.</p>
-<p>PMClient executes the training logic, during which it generates GET and
UPDATE requests. A request received at the worker’s main thread contains
ID of the PMClient instance. The worker determines which server to send the
request based on its content, then sends it via the corresponding socket.
Response messages received from any of the server socket are forwarded to the
in-proc ROUTER socket. Since each response header contains the PMClient ID, it
is routed to the correct instance.</p></div>

-<p>The main thread has a ROUTER socket to communicate with background

-<p>It forwards the requests from workers to background servers. There can be
multiple servers.If all servers maintain the same (sub) ParamShard, then the
request can be forwarded to any of them. Load-balance (like round-robin) can be
implemented in the stub to improve the performance. If each server maintains a
sub-set of the local ParamShard, then the stub forwards each request to the
corresponding server. It also forwards the synchronization requests from remote
servers to local servers in the same way.</p>
-<p>In the case of neural network partition (i.e., model partition), neighbor
layers would transfer data with each other. Hence, the ROUTER would forwards
data transfer requests from one worker to other worker. The stub looks up the
location table to decide where to forward each request.</p></div>

demonstrates different types of messages exchanged in the system.</p>
-
-<ol style="list-style-type: decimal">
-
-<li>Requests generated by PMClient consist of the parameter content (which
could be empty), followed by the parameter ID (key) and the request type

the server’s main thread consists of all the frames in (3), followed by
