| Abstract | Abstract. MPI standard offers a set of topology-aware interfaces that can be used to construct graph and Cartesian topologies for MPI applications. These interfaces have been mostly used for topology construction and not for performance improvement. To optimize the performance, in this paper we use graph embedding and node/network architecture discovery modules to match the communication topology of the applications to the physical topology of multi-core clusters with multi-level networks. Micro-benchmark results show considerable improvement in communication performance when using weighted and network-aware mapping. We also show that the implementation can improve communication and execution time of the applications. |
