DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: File layout of array data is a critical factor that effects the behavior of storage caches, and has so far taken not much attention in the context of hierarchical storage systems. 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.
