【摘要】 在当前程序自动并行化尚未有突破性进展的形势下，我们提出了小粒度自动并行，大粒度程序员导航的并行化方案，并侧重大粒度并行，给出了对Ｃ语言加入并行描述成分的并行程序设计语言模型ＰＡＲＡ－Ｃ。该文介绍了作者设计ＰＡＲＡ－Ｃ的目的，及其基于大粒度的并行的创建、读写冲突的同步实现、数据通讯等并行特征。在共享内存的存储模式下，对上述并行要素的实现从预编译和运行时两个方面进行了讨论，并提供了帮助程序员并行导航的辅助手段更多还原

【Abstract】 In the situation when automatic parallelizer has not made essential progress, we present a new solution——instruction level automatic parallelization and programmer navigation for coarse-grain parallelization. We propose a parallel programming language PARA-C extended from C language by adding parallel elements. In this paper, we discuss two phases of the language realization: pre-compiling and runtime environment. An auxi￣liary and optimization method is presented subsequently.更多还原
