Testing code

It's always a bit of an embarrassment when talking about your code tests. I think most developers know that they don’t have enough tests or that their tests are not good enough.

There is never enough time to either write or to run tests that fully cover all possibilities so, like all types of programming, testing becomes a compromise where you try to make the best use of the limited resources available for testing.

Hierarchy of multiscale modeling

Over the last year I've been working with Prof. Jon Essex of Southampton University on an ARCHER eCSE project with the pithy title of "Implementation of Dual Resolution Simulation Methodology in LAMMPS".  

So what do I mean by dual-resolution simulations?

Developing for the real world

As part of a recent ARCHER eCSE project I developed a new parallelisation strategy for a computational simulation application to enable it to scale efficiently to larger process counts. We managed to significantly reduce the parallel overheads, so the code was accepted into the main repository for users to exploit.

Summer of HPC comes to an end

This week we said goodbye to our Summer of HPC students Anna, Marta and Tomislav.

These students from around Europe have spent the last 7 weeks with us at EPCC immersed in HPC, and each working on a specific project in the field. This is a great because not only do they gain experience and interest in HPC but we also get a useful, tangible, outcome from these projects.

With my Software Sustainability Institute hat on, I recently participated in a back-to-back Data Carpentry and Software Carpentry course sponsored by the University's Research Data Service here at the University of Edinburgh. The courses were held in the main University library in a gorgeous room with a glass wall, providing a rather distracting view of the Meadows parkland. 

​A not-so-brief history of research software engineers

This guest post by Simon Hettrick, Deputy Director of the Software Sustainability Institute, explains how the role of research software engineer has gained greater definition and recognition.

On a beautifully sunny day in March 2012, a small group met at Queen’s College Oxford and challenged a long-standing problem: why is there no career for software developers in academia? They didn’t know it at the time, but this meeting led to a nationwide campaign that created a vibrant and rapidly growing community, and established a new role in research: the Research Software Engineer.

Summer of HPC visitor Tomislav Subic gives a summary of his project at EPCC: a visualisation of the UK Met Office's weather model.

A legend says that there was once a warm sunny day in Scotland. I have started my quest to find out if the myth was true, but I was not the only one.
