Irregular algorithms are organized around pointer-based data structures such as graphs and trees, and they are ubiquitous in applications. Recent work by the Galois project has pr...
Gather and scatter are data redistribution functions of longstanding importance to high performance computing. In this paper, we present a highly-general array operator with power...

Executing the legacy program over grid is very important and necessary. To reuse the legacy program, we developed a method based on Component for executing the legacy code. We can...
Abstract. This paper presents PerWiz, a performance prediction tool for improving the performance of message passing programs. PerWiz focuses on locating where a significant impro...
We introduce a new performance metric, called Load Balancing Factor (LBF), to assist programmers with evaluating different tuning alternatives. The LBF metric differs from traditi...
