Design and implementation of SDN MPI_Bcast
In this study, high-speed MPI_Bcast leveraging Software-Defined Networking (SDN) has been explored. MPI (Message Passing Interface), a de facto starndard library for distributed and parallel computing, provides a suite of APIs(Application Programming Interfaces) for inter-process communication. This study, in particular, focuses on MPI_Bcast, a collective communication API, with which programmers can send a specific data from a process to other remained processes and aims to reduce MPI_Bcast execution time. Speficically, we have been developing the SDN controller that control MPI_Bcast traffic on the interconnect through the consideration on MPI_Bcast communication pattern and the underlying computing and network environment.
