Following on from prior work by Dr. Matt Watkins, a member of Dr. Ben Slater's research group at University College London, an application for dCSE support was made by Dr. Slater and Dr. Joost VandeVondele of the University of Zurich to further optimise the code for HECToR. 6 months of development effort was provided by Iain Bethune, an Applications Consultant at EPCC, between August 2008 and July 2009. All the objectives set out in the proposal were acheived, and the performance gains achieved are described in detail below.
