Abstract

In this work we propose a run-time approach for the efficient parallel execution of doacross loops with indirect array accesses by means of a graph partitioning strategy. Our approach focuses not only on extracting parallelism among iterations of the loop, but also on exploiting data access locality to improve memory hierarchy behavior and thus the overall program speedup. The effectiveness of our algorithm is assessed in an SGI Origin 2000.
