| 摘 要： | 异构重构计算是目前高性能计算的研究热点.由于应用任务的异构性,以及体系结构的可重构性,导致异构重构计算的性能分析非常困难,现有的并行计算性能分析方法不再适用.本文提出一种基于应用任务调度的性能分析方法,该方法以异构重构计算系统模型和应用任务模型为基础,利用异构匹配、重构耦合矩阵,实现应用任务和处理部件的优化选择和耦合匹配,通过调度算法求出应用任务在异构重构计算系统中的完成时间,并进行了实例分析.

| Abstract: | Right now,heterogeneous & reconfigurable computing is a research hot in the area of high performance computing.Due to the heterogeneity of application tasks and reconfigurability of system architecture,performance analysis for heterogeneous & reconfigurable computing becomes rather difficult.Unfortunately,the existing techniques and methods are no longer suitable for use.This paper presents a performance analysis method based on task scheduling.It builds on system architecture model and task model of heterogeneous & reconfigurable computing.By making use of heterogeneity matching matrix and reconfigurability coupling matrix we achieve optimal selection and matching between computational tasks and processing units.Through task scheduling algorithm,the completion time of application task run on heterogeneous & reconfigurable computing system can be calculated.Finally,we carry out case study. |
