• 論文抄録 / 内容記述: This paper describes the architecture of a high performance particle simulation machine DEM-1 (Dentsudai EAM Machine-1) for short-range particle interaction computations. All existing particle simulation machines have specialized pipelines to calculate long-range particle interactions effectively. However their ability to perform particle simulations efficiently diminishes with short-range interactions. Communication cost in particle simulations will play a significant role in performance when the computation cost becomes O(N) where Nis the number of particles. In DEM-1 a three-dimensional torus high-speed network reduces this cost while 2048 local processors perform time integration. Specially designed cutoff units reduce the number of calculations in DEM-1. Each specialized pipeline consists of a dedicated data path supported by position vector pre-fetch dual ported memory (pre-fetch DPM). A prototype pipeline has been implemented on an FPGA test-bed. Performance of the DEM-1 pipeline has been measured and total system performance has been estimated with very large-scale Embedded Atom Method (EAM) molecular dynamics simulations.
