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.

Intel Parallel Computing Center collaboration with Colfax

We're just kicking off a week's collaboration with Colfax, a US technology company that collaborates heavily with Intel on Xeon Phi optimisation and training for the Xeon Phi.

ExTASY project logo

Over 18 months ago, we kicked off the ExTASY project. Our lofty aim was to tackle one of the 'Grand Challenges' of biochemistry - effective sampling of complex biomolecules using Molecular Dynamics to provide a physical understanding of their function and behaviour.

The Mozilla Lab Global Science Sprint 2015

I had not intended to go to the Mozilla Global Science Sprint 2015. However, EPCC acted as a hub for local developers who wanted to participate and Neil Chue Hong (Director of the Software Sustainability Institute, and based here at EPCC) asked me to set up the room and make the initial connection in case he was unavailable. I managed to set up the servers and then stayed.

So what is the Mozilla Global Science Sprint?
