Achieving High Performance-Per-Watt for Seismic Workloads on NEC Aurora TSUBASA or Vector Engine (VE)


The NEC Aurora TSUBASA or Vector Engine (VE) has considerable memory bandwidth and vectorization capability and a relatively low power usage for those capabilities. Many Oil&Gas seismic codes benefit significantly from vectorization and high bandwidth. I talk about an elastic wave equation solver implemented using NEC C++ and how it achieves very competitive performance against traditional CPUs both in terms of raw performance as well as performance-per-watt.
