Abstract

Large scale irregular applications involve data arrays and other data structures that are too large to fit in main memory and hence reside on disks; such applications are called out-of-core applications. We present a design and implementation of lip, a new parallel library that is intended to efficiently support parallel execution of irregular out-of-core codes on parallel systems. We discuss the lip structure and application interface, as well as an application that has been implemented using that interface. The library has been implemented on top of MPI/MPI-IO and, therefore, is fully portable.We introduce preliminary performance results from a template CFD codes to demonstrate the efficacy of the presented techniques.
