> SINGA has a set of message passing interface following ZeroMQ.
> Currently, the underlying implementation uses ZeroMQ.
> Another commonly used message passing library is MPI.
> The comparison between ZeroMQ and MPI is discussed herer http://singa.apache.org/docs/communication.html.
> This ticket is going to implement the message passing interface using MPI.
> It would be used for optimize the communication between GPUs using RMDA.
> Particularly, first we need to implement the intra-process communication by ourselves,
e.g., using a global message queue. The Send and Recv functions operate against the global
message queue. Second, we need to implement the inter-process communication using MPI, which
involves the MPI initialization and message sending and receiving.
