精确且高效的依赖关系测试对于并行化编译器的有效性至关重要。本文提出了一种基于对带下标的变量引用对进行分类的依赖关系测试方案。针对某些类别的数组引用，给出了精确且快速的依赖关系测试，同时给出的实证结果表明这些引用在科学Fortran代码中占主导地位。赖斯大学正在其并行化编译器PFC和并行编程环境ParaScope中实现这些依赖关系测试。
Precise and efficient dependence tests are essential to theeffectivermss ofaparallelizing compiler. This paper proposes a dependence testing scheme based on classifyingpairs ofsubscripted variable references. Exact yet fast dependence tests are presented for certain classes ofarray references, as well as empirical results showing that these references dominate scientific Fortran codes. These dependence tests are being implemented at Rice University in both PFC, aparallelizing compiler, and ParaScope, a parallel programming environment,
