科学计算程序在FT64流处理器上的实现、优化和评测

Implementation,Optimization and Evaluation of Scientific Applications on the FT64 Stream Processor

流体系结构是一种适应VLSI工艺发展的新型体系结构,它是否对科学计算程序有效是一个广泛关注的问题。本文选取NASA并行测试程序集中的一个数据密集型程序MG,研究了它在一个64位的面向科学计算设计的流处理器FT64上的实现和优化问题。在FT64上的实测表明,经过面向片上存储层次的优化,FT64能够达到与Itanium 2处理器相当的性能。

The stream architecture is one of the emerging architectures that adapt well to the development of VLSI technologies, its efficiency to scientific applications is widely concerned. In this paper, we select a data-intensive program MG from the NASA Parallel Benchmarks and explore its implementation and optimization on the FT64 stream processor, which is the first implementation of a 64-bit stream processor for scientific computing. The evaluation shows that FT64 achieves a comparable performance to the Itanium 2 processor after optimizations towards on-chip memory hierarchies.
