We have just reached the end of a short project collaborating with Atmospheric Geochemists at the universities of Edinburgh and Bristol. After they purchased two machines each, both with dual Intel Xeon Ivy-bridge 12-core CPUs and NVIDIA Tesla K20x GPUs, EPCC was tasked to investigate the feasability of using the GPUs to improve the performance of their software.

In 2013, the DiRAC consortium rolled out the DiRAC driving licence, a software skills aptitude test for researchers wanting to use DiRAC's high-performance computing resources. Now ARCHER, the UK National Supercomputing Service, is to roll out an ARCHER driving test.
Despite their similar names, these tests differ in nature, intent, scale and reward. In this post, EPCC's Mike Jackson, Andrew Turner and Clair Barrass compare and contrast these two supercomputer tests.

Last week EPCC's ARCHER training team ran another Software Carpentry workshop here in Edinburgh, on 3rd and 4th of December. The workshop provided attendees with an introduction to version control and Git, building programs with Python, automating tasks with Make, and how (and how much) to test programs. These were set within the context of best practices for scientific computing.

The NESS project is developing next-generation sound synthesis techniques based on physical models of acoustical systems. One key system targeted by NESS is the acoustics of 3D rooms.
Computer simulation of 3D room acoustics has many practical applications such as the design of concert halls, virtual reality systems, and artificial reverberation effects for electroacoustic music and video games.
