Abstract: This paper describes new compiler and run-time techniques to handle array accesses involving several levels of indirection such as those arising in sparse and irregular problems. The lack of information at compile-time in such problems has typically required the insertion of expensive runtime support. We propose new data distributions which can be used with standard sparse matrix representations to achieve much more efficient resolution of indirections at runtime. Unlike previous methods, our...
