Array privatization is one of the most effective loop transformations for the exploitation of parallelism. This transformation technique privatizes arrays according to the information of the data dependence analysis, which eliminates the memory-related dependences, i.e. anti and output dependences, to make the loop execute parallel.

数组私有化是开发并行性最有效的循环变换技术之一，它以数据依赖关系分析为依据对数组进行私有化，消除循环中的存储关联数据相关，即反相关和输出相关，使循环可以并行执行。
