The Collaborations Workshop (CW) is coming home to Edinburgh. It will be held on 21st-22nd March in the Royal College of Surgeons with an optional hack day on 23rd of March.  The series of CWs were originally started under the now defunct Open Middleware Infrastructure Institute UK (OMII-UK) that held two workshops in Edinburgh in 2009 and 2010 in what was then the National e-Science Institute in Edinburgh. The aim of these workshops was to get researchers to come together, talk, avoid reinventing the wheel and to establish fruitful collaborations. It was, and has remained, a most excellent networking event.

Lancaster University, 7-8 April 2016

The programme for the HPC-CORE (High Performance Computing-based Computational fluid dynamics for Offshore Renewable Energy) workshop has now been published. This event brings together scientific specialists from Engineering, Atmospheric and Environmental Sciences, and HPC experts to discuss the state of the art for simulation software, and the leading-edge simulations being undertaken with such software.

Getting hands-on with ExTASY

One of the projects I'm currently leading at EPCC is ExTASY, which is building an 'Extensible Toolkit for Advanced Sampling and analYsis'.  I've blogged in the past about the goals of the project, and the painful process leading up to our first public release. As the project is now well into its final year, we are turning our attention to community outreach - showing off what we have built to the biomolecular simulation community and getting their feedback.

Since 2013, EPCC has hosted PRACE Summer of HPC (SoHPC) students for eight weeks from early July. I was involved with SoHPC for the first time this year as mentor of two Masters students, Jana Boltersdorf from FH Aachen University of Applied Sciences (Germany) and Ondřej Vysocký from Brno University of Technology (Czech Republic).

Adept Benchmark Suite released!

After a couple of years of measuring and trying to understand the power and energy consumption of (parallel) software and hardware, we have now released one of the key tools that we've been using as part of this research: the Adept Benchmark Suite!

While measuring performance (ie time to solution) is well understood, doing the same for power or energy is much less straightforward and often hardware dependent. The Adept Benchmark Suite relies on third party power measurement (such as instrumentation of the hardware) to be in place. However, to get users started with initial experiments, we provide a library to use RAPL (Running Average Power Limit) counters on Intel processors to measure the power of CPUs and memory, as well as some example code on how to use this library within the Adept Benchmarks.

Hackathons as an educational tool

They go by many names: “Hackathons”, “Hackdays, “Hackfests”, or my personal favourite “Code Dungeons”. Despite having heard most of these terms repeatedly over the years, I had no personal experience of them. To me, they sounded like competitive events to show off one’s skills. However, after attending Eurohack 2015 (yes, another alias) this past July, as well as a similar event organised earlier in the year by Intel, I was surprised to discover a whole new aspect of Hackathons: education and scientific advancement.

War in the coding world

It's not often that the internecine rivalries of the HPC research and development community spill over into the public arena. However, a video recently posted on YouTube (and the associated comments), ostensibly a light-hearted advert for a SC15 tutorial on heterogenous programming, shows how real and deep these rivalries can be.

Day 5 - Wrapping up the week

The final analysis and future plans

A week ago we finished our 5 days of intensive work optimising CP2K (and to a lesser extent GS2) for Xeon Phi processors. As discussed in previous blog posts (Day4, Day3, Day2, Day1), this was done in conjunction with research engineers from Colfax, and built on the previous year's work on these codes by EPCC staff through the Intel-funded IPCC project.
