应用编译技术优化核外计算程序

Application of compiler optimizing technology on out-of-core computations

阐述了一种适用于核外计算程序的变换技术,它通过联合使用循环变换和数据变换这两种编译优化技术来增强程序的局部性,提高数据存取效率。该方法不仅能优化单独一个嵌套循环,还能同时处理多个嵌套循环。实验结果表明了该方法能显著提高核外计算的性能。

A transformation technique which is suitable for out-of-core program was described. Joint use of loop and data transformations help enhance the locality. This solution can not only optimize a single loop nest, but also handle a sequence of loop nests. The experimental results show that the method significantly improves the efficiency of out-of-core computation.
