| Outline of Final Research Achievements |
This research has realized a parallel distributed computing environment that accelerates MPI execution, taking advantage of network programmability brought by SDN (Software Defined Networking) and MPI program characteristics. In more detail, the proposed method in this paper dynamically controls a sequence of network flows on OpenFlow Controller in a software-programming manner. We have shown that the proposed method in this research is effective to reduction of execution time for MPI collective communications such as MPI_Bcast and MPI_Allreduce.
