Abstract

Most scientific programs have large input and output data sets that require out-of-core programming or the use of virtual memory management (VMM). Often, VMM is not an effective approach because it often results in substantial performance reduction. In contrast, compiler driven I/O management allows a program's data sets to be retrieved explicitly in parts. In this paper a modified Comanche (Compiler Managed Cache) system is presented.
