摘要： 在程序中,公用块的使用有时是为了重复利用某一内存区域,这给数据划分和分布带来了不必要的麻烦。该文提出了数据生Fortran命期的概念,借鉴数组私有化中的相关技术,通过计算子程序公用块中数组的暴露集等方法,对非必要内存重用的变量进行识别COMMON和处理。

Abstract: Sometimes the COMMON variables in the Fortran program are used to make repeated use of the memory space. It brings difficulty to the partition and the distribution of the data. We present the concept of the lifetime of the data. The unnecessary-memory-reuse COMMON variable can be recognized and processed correctly by computing the exposed set of the array. The technology is similar to that used in the array privatization.
