Query: High-Performance High-Order Stencil Computation on FPGAs Using OpenCL   In this paper we evaluate the performance of FPGAs for high-order stencil
computation using High-Level Synthesis. We show that despite the higher
computation intensity and on-chip memory requirement of such stencils compared
to first-order ones, our design technique with combined spatial and temporal
blocking remains effective. This allows us to reach similar, or even higher,
compute performance compared to first-order stencils. We use an OpenCL-based
design that, apart from parameterizing performance knobs, also parameterizes
the stencil radius. Furthermore, we show that our performance model exhibits
the same accuracy as first-order stencils in predicting the performance of
high-order ones. On an Intel Arria 10 GX 1150 device, for 2D and 3D star-shaped
stencils, we achieve over 700 and 270 GFLOP/s of compute performance,
respectively, up to a stencil radius of four. These results outperform the
state-of-the-art YASK framework on a modern Xeon for 2D and 3D stencils, and
outperform a modern Xeon Phi for 2D stencils, while achieving competitive
performance in 3D. Furthermore, our FPGA design achieves better power
efficiency in almost all cases.
