Software Optimisation ToolsCrystallographic structure refinement can involve hundreds of millions of calculations for a single iteration of structure refinement. The following freely available tools help identify bottlenecks in software implementations, and allow testing of potentially faster algorithms and compiler options. A time-critical portion of code from the crystallographic refinement package CRYSTALS is analysed here.

DetOx: A Program for Determining Anomalous Scattering Factors of Mixed-Oxidation-State Species (K.J. Sutton, S.A. Barnett, K.E. Christensen, H. Nowell, A.L. Thompson, D.R. Allan and R.I. Cooper)

J. Sync. Rad (2013). 20, 200–204. [ doi:10.1107/S0909049512044007 ]

Overlapping absorption edges will occur when an element is present in multiple oxidation states within a material. DetOx is a program for partitioning overlapping X-ray absorption spectra into contributions from individual atomic species and computing the dependence of the anomalous scattering factors on X-ray energy. … Read the rest
