MABAKANE, Mabule Samuel; MOEKETSI, Daniel Mojalefa e LOPIS, Anton S.. Scalability of DL_POLY on High Performance Computing Platform. SACJ [online]. 2017, vol.29, n.3, pp.81-94. ISSN 2313-7835. http://dx.doi.org/10.18489/sacj.v29i3.405.
This paper presents a case study on the scalability of several versions of the molecular dynamics code (DL_POLY) performed on South Africa's Centre for High Performance Computing e1350 IBM Linux cluster, Sun system and Lengau supercomputers. Within this study different problem sizes were designed and the same chosen systems were employed in order to test the performance of DL_POLY using weak and strong scalability. It was found that the speed-up results for the small systems were better than large systems on both Ethernet and Infiniband network. However, simulations of large systems in DL_POLY performed well using Infiniband network on Lengau cluster as compared to e1350 and Sun supercomputer.
