摘要

This particular parallel programming model using threaded message passing interface (MPI) was implemented on a special architecture, the Adapteva Epiphany. The Epiphany IV architecture is comprised of 64 cores arranged in 2D tiled mesh network-on-chip (NoC) RISC with minimal functionality. The authors run threaded MPI on four different benchmarks-dense matrix-matrix multiplication, N-body particle interaction, five-point 2D stencil update, and 2D fast Fourier transform (FFT); according to the authors, results show "high computational energy efficiency [and scalability] for both integer and floating point calculations."
