CP2K Summer School group photoSeptember 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.

Supercomputing at Bang Goes The Borders

Success in the Build-a-computer challenge!Last weekend my EPCC colleagues Gordon, Alistair, Anne and I were at Bang Goes The Borders at St. Mary's School in Melrose.

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.

Roborace DevBot on the trackAutonomous racing

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.

Secure access to remote systems

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.

The Power Benchmarking Game

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.

Summer of HPC comes to an end

This week we said goodbye to our Summer of HPC students Anna, Marta and Tomislav.

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.

​ Exploring energy efficiency

The ADEPT project is creating tools that can be used to design more efficient HPC systems.

Energy efficiency is one of the key challenges of modern computing – in an era where even the most efficient supercomputers come with massive energy bills, technology that can help to increase energy efficiency is critical to sustainable HPC development.
