The main contribution of this paper is a compiler-driven=0Afile layout optimization scheme for hierarchical storage caches. This approach, fully automated within an optimizing compiler, analyzes a multi-threaded application code and determines a file layout for each disk-resident array referenced by the code, such that the performance of the target storage cache hierarchy is maximized. We=0Atested our approach using 16 I/O intensive application programs=0Aand compared its performance against two previously proposed=0Aapproaches under different cache space management schemes.=0AOur experimental results show that the proposed approach improves the execution time of these parallel applications by=0A23.7% on average.
