For the last five years, I've been involved in the development of the CP2K materials science code, mostly in terms of improving its performance and scalability and porting to new systems. During that time a great deal of new functionality has been added, as well as additional input file options, libraries and autotuning capability to enable maximum performance on any given architecture. However, these improvements have come at the cost of increased complexity - and CP2K already has a fearsome reputation among researchers for being very hard to use!

The NAIS project (Numerical Algorithms and Intellegent Software), which EPCC is a member of, has recently purchased 8 NVidia K20 GPGPUs, and associated computer nodes to house them, for use by NAIS members and researchers.

This summer we were fortunate to have a student, Antoine, work on our dinosaur-racing outreach project as part of the Summer of HPC programme. Antoine did a great job in turning the demo from a simple prototype into a much more polished, usable showcase for how HPC plays a vital role in a variety of sciences. If you are a regular reader of the EPCC blog then you might have already read some posts about this application - see my initial blog post, and Antoine's progress updates here and here.

The programme for the British Science Festival 2013 in Newcastle has now been released and EPCC is running two events this year.The first is an exhibition booth in the Discovery Science Centre on Saturday 7th September, where we will be showing off a range of HPC demos including the Virtual Paleontology 'Dinosaur Racing' game currently being developed by one of our PRACE Summer of HPC students, as well as some other new ideas developed during Innovative Learning Week on our MSc, and of course a range of HPC hardware old and new.

The Animal Simulation project, run at the University of Manchester, aims to create realistic simulations of animals both present and extinct. By combining the expertise of a number of scientific fields along with high performance computing (HPC), they have created GaitSym, a code capable of realistically simulating movements of animals based on a 3D model of their skeleton and biological data.

Since June 2012, The Software Sustainability Institute and Software Carpentry have been working with the DiRAC consortium to develop a "driving test" or basic software skills aptitude test. The test is now ready to be rolled out across DiRAC, the UK's integrated supercomputing facility for theoretical modelling and HPC-based research in particle physics, astronomy and cosmology.

Have you ever wanted to send a message using MPI to a specific thread in a multi-threaded MPI process? With the current MPI Standard, there is no way to identify one thread from another. The whole MPI process has a single rank in each communicator.
