| Abstract(in English) | Stencil computation is one of the important kernels in scientific computations, however, the sustained performance is limited by memory bandwidth on multi-core processors and GPGPUs due to its small operational-intensity. In this paper, we propose a scalable streaming-array (SSA), which allows multiple FPGAs to achieve linearly-scalable stencil computation by deeply pipelining with a constant external-memory bandwidth. We present a design of SSA and formulate a performance model of the pipelined execution. For 2D Jacobi computations, SSA implemented on nine Stratix III FPGAs with the memory bandwidth of only 2 GB/s achieves 260 GFlop/s, corresponding to 87.4 % of the peak, due to the linear speedup obtained for larger than medium-sized computation. |
