Design and Analysis of the BlueGene/L Torus Interconnection Network

BlueGene/L (BG/L) is a 64K (65,536) node scientific and engineering supercomputer that IBM is developing with partial funding from the United States Department of Energy. This paper describes one of the primary BG/L interconnection networks, a three dimensional torus. We describe a parallel performance simulator that was used extensively to help architect and design the torus network and presen...

Adjacency-based data reordering algorithm for acceleration of finite element computations

Effective use of the processor memory hierarchy is an important issue in high performance computing. In this work, a part level mesh topological traversal algorithm is used to define a reordering of both mesh vertices and regions that increases the spatial locality of data and improves overall cache utilization during on processor finite element calculations. Examples based on adaptively create...
