TPLS (Two-Phase Level Set) is a Computational Fluid Dynamics code developed by Dr Prash Valluri of the University of Edinburgh's School of Engineering and Dr Lennon Ó Náraigh of University College Dublin. It simulates the interface between two fluid phases, a phenomenon with a number of industrial applications including oil and gas hydrate transport, cleaning processes, distillation/absorption, and evaporative cooling of microelectronics.

Changing technology – thinking about digital preservation

How do we deal with technology change? Ever thought about accessing the stuff you did twenty years ago? What’s that? You are having a hard time getting a floppy disk drive? Maybe the data format is unreadable or the media has been damaged? 8-inch, 5,25-inch, and 3,5-inch floppy disks: Public Domain 7 June 2009: George Chernilevsky

This is a problem that will continue to face us in many fields: how do you ensure that today’s data is still accessible in twenty or even fifty years' time? For a lot of areas, maybe we do not want to bother, it's the here and now that counts.

Opening OpenACC

Programmability of GPUs (or accelerators in general) has improved since the days of the OpenGL shaders. First CUDA, and OpenCL later, have evolved to offer a reasonable way of programming efficient algorithms onto GPUs. However, despite this improvement, there is still a lot of effort involved in the development of code for accelerators. This is inevitable sometimes: if you have a particular algorithm and you want to have the maximum performance possible for a particular accelerator architecture, and you have the time to do it, you can immerse yourself in the marvellous world of CUDA/OpenCL low-level optimisation and stop reading. If time is critical for you, as it is for me, then you will love the latest advance in accelerator programmability: OpenACC.
