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.

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.

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.

Jana Boltersdorf is visiting EPCC as part of the PRACE Summer of HPC programme. Together with Ondrej Vysocky she has been working on a project that is Developing the user interface for the Fluctuating Finite Element Analysis (FFEA) tool.

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.

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.

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?

The PERICLES project has been running for just over two years now. Its goal is a lofty one - to ensure that today's digital data and art can be preserved for use in the future. Sounds dead easy, no?
