Number Theory - the study of the integers - is perhaps one of the purest branches of maths and is not well-known for setting the headlines alight.
Along with the proof of Fermat's Last Theorem in 1995, which earned a knighthood for Sir Andrew Wiles, there was a lot of excitement about the Twin Prime Conjecture a few years ago, beginning a new spurt of progress towards the solution of this thorny mathematical problem.

September seems to have passed by in a bit of a blur, and it's already a whole month since the CP2K Summer School, which we ran at King's College London (23-26th August), so I thought it would be a good time to give an update on the recent activities of the CP2K-UK project.

Developing for the real world
As part of a recent ARCHER eCSE project I developed a new parallelisation strategy for a computational simulation application to enable it to scale efficiently to larger process counts. We managed to significantly reduce the parallel overheads, so the code was accepted into the main repository for users to exploit.

BGTB is a family-friendly science festival held every September in the Scottish Borders - this is the fifth year in a row we've run a workshop there and it was good to see some repeat visitors from previous years as well as new faces, eager to find out about HPC and Computer Simulation.

Recently EPCC's Alan Gray and I attended a workshop at Donington Park held by Roborace. For those who've not heard of Roborace, it's a project to build and race autonomous cars, along the lines of Formula 1 but without any drivers or human control of the cars. Actually, it's more like Formula E but without drivers, as the plan is for the cars to be electric.

06/09/16: As pointed out by my colleague Stephen in the comments after this post, the way to solve most of these issues is to tunnel the key authentication and therefore bypass the need to have private keys anywhere but on my local machine. I'm always learning :)
Password vs key
Having to remember a range of passwords for systems that I don't use regularly is hard.
You can use a password manager, but that only helps if I'm only ever trying to log in from my own laptop. If I have to log in from someone else's machine for any reason then I'd need to know the password.

As we continue to scale our HPC systems, the energy cost of doing so becomes an increasingly large and potentially limiting factor.
One of the most important aspects of addressing the challenges of energy efficient computing is having a solid understanding of how various design choices, in both software and hardware, affect the overall energy usage of your system and application.
In his guest post, PhD student Blair Archibald discusses how the Adept project is contributing to knowledge in this area.

These students from around Europe have spent the last 7 weeks with us at EPCC immersed in HPC, and each working on a specific project in the field. This is a great because not only do they gain experience and interest in HPC but we also get a useful, tangible, outcome from these projects.
