Debugging Numerical Software workshop, University of Bath

On 4-5 June 2018, I attended a workshop on Debugging Numerical Software at University of Bath. The workshop featured a variety of debugging-themed talks from experienced developers of numerical software, as well as group  discussion sessions and an innovative interactive “bug hunt” session.

I submitted a bug for discussion during the bug hunt session (slides and source code can be found at the public github repository created for the session). The bug was originally encountered as unexpected changes in the behaviour of Fortran code (ONETEP) when compiled with/without OpenMP support. See the slides I produced for the workshop for further information: slide 1, slide 2 (slide 2 contains some useful information about how compilers silently change how variables are allocated when OpenMP flags are used).

During the bug hunt session we were able to create a minimal working example (MWE) for my bug. This was a nice outcome, given that a MWE had proven elusive in my investigations prior to the workshop.

Updated CV, publications list, and slides from talk at “Modelling and Measuring Water in Complex Environments” symposium

I have updated the brief CV and publications list in the Work page and added slides from a recent talk I gave at the “Modelling and Measuring Water in Complex Environments” symposium at the University of Southampton. The talk covered the implicit solvent model implemented in ONETEP and our recent work further extending and developing this model. It also included some examples of large-scale applications of the solvent model using ONETEP.

Slides for talks at the RSC Theoretical Chemistry Group Conference and 252nd ACS National Meeting & Exposition

I have just uploaded the slides from two recent talks I gave on my work implementing meta-GGAs in the ONETEP linear-scaling electronic structure code. The first talk was given at the RSC Theoretical Chemistry Group Conference in Nottingham, UK. The second was given at the 252nd ACS National Meeting & Exposition in Philadelphia, US. The PDFs can be downloaded from the Work page.
