Abstract

Current virtual memory systems provided for scalable computer systems typically offer poor performance for scientific applications when an application's working data set does not fit in main memory. As a result, programmers who wish to solve "out-of-core" problems efficiently typically write a separate version of the parallel program with explicit I/O operations. This task is onerous and extremely difficult if the application includes indirect data references. A promising approach is to develop a language support and a compiler system on top of an advanced runtime system which can automatically transform an appropriate in-core program to efficiently operate on out-of-core data. This approach is presented in this paper. Our proposals are discussed in the context of HPF and its compilation environment.
