Query: Leveraging MPI-3 Shared-Memory Extensions for Efficient PGAS Runtime
  Systems   The relaxed semantics and rich functionality of one-sided communication
primitives of MPI-3 makes MPI an attractive candidate for the implementation of
PGAS models. However, the performance of such implementation suffers from the
fact, that current MPI RMA implementations typically have a large overhead when
source and target of a communication request share a common, local physical
memory. In this paper, we present an optimized PGAS-like runtime system which
uses the new MPI-3 shared-memory extensions to serve intra-node communication
requests and MPI-3 one-sided communication primitives to serve inter-node
communication requests. The performance of our runtime system is evaluated on a
Cray XC40 system through low-level communication benchmarks, a random-access
benchmark and a stencil kernel. The results of the experiments demonstrate that
the performance of our hybrid runtime system matches the performance of
low-level RMA libraries for intra-node transfers, and that of MPI-3 for
inter-node transfers.
