Abstract

A plane wave self-consistent field calculation was parallelized over two node cards of an IBM BlueGene/P supercomputer. A maximum speedup of 9x was measured in Virtual Node execution mode. The observed performance improvements are consistent with Amdahl's law for an algorithm that is approximately 89% parallelizable.
