一种流处理器体系结构MASA及其在流体力学计算中的评测

MASA Stream Architecture and Evaluating for a Fluid Computing Application

提出了面向科学计算的64位流体系结构——MASA,它具有强局域性、并行性、解耦合访存操作和计算操作等特征,特别适合于计算密集型的并行应用.作者使用时钟精确的模拟器评测了流体力学中的典型应用在MASA上的运行性能,结果表明MASA在500MHz的情况下能够获得比1.6GHz的Iantium2近4倍的加速,证实了流体系结构在高性能计算领域的极大潜力.

This paper presents MASA stream architecture which supporting 64b operation for scientific computing, and which characteristics are stress locality, parallelism, decoupling of memory operations. It matches the capabilities of modern semiconductor technology with computer-intensive parallel applications and allows for high performance of compiler optimized code. Given a fluid computing application as a case, the authors used a cycle-accurate hardware simulator to analyze the performance of the implementation and to measure application run-time. A comparison with the code, tuned for traditional general purpose processors, confirms the stream processor＇s potential to deliver high performance.
