The effective exploitation of current high performance computing (HPC) platforms in molecular simulation relies on the ability of the present generation of parallel molecular dynamics code to make effective ritilisation of these platforms and their components, including CPUs and memory. In this paper, we investigate the efficiency and scaling of a series of popular molecular dynamics codes on the UK's national HPC resources, an IBM p690+ cluster and an SGI Altix 3700.
Focusing primarily on the AMBER, DL_Poly and NAMD simulation codes, we demonstrate the major performance and scalabilitv advantages that arise through a distributed, rather than a replicated data approach.
