摘要

估算数据并行算法的相对执行时间的框架!在SIMD和SPMD(单程序多数据)计算模式的环境下,给出了hms的计算方法。给定一个使用语法与模式无关的语言的数据并行程序,以及关于指令执行时间特征的经验信息,长期目标是在编译时确定一种实现,该实现能够为具有SIMD和SPMD并行性的异构系统带来最佳执行时间。

A Framework for Compile-Time Selection of Parallel Modes in an Simd/spmd Heterogeneous Environment
A framework for estimating the relative execution time of a data-parallel algorir!hm in an environment capable of the SIMD and SPMD (Single Program Multiple Data) modes of computation is presented. Given a data-parallel program in a language whose syntax is mode-independent, and empirical inj5ormation about instruction execution time characteristics, the long-term goal is to determine at compile time an implemenlation that results in an optimal execution time for a heterogeneous system capable of SIMD and SPMD parallelism.
