ARCHER (Advanced Research Computing High End Resource) is the next national HPC service for academic research. The service comprises a number of components: accommodation provided by the University of Edinburgh; hardware by Cray; systems support by EPCC and Daresbury Laboratory; and user and computational science and engineering support by EPCC.

DiRAC driving test comes to Edinburgh

My colleague Mike Jackson recently posted about the DiRAC driving test. DiRAC is the UK's integrated supercomputing facility for theoretical modelling and HPC-based research in particle physics, astronomy and cosmology and is used by numerous researchers with diverse backgrounds. Whilst much of their work is very different, one commonality is that it often requires in-depth technical and software engineering techniques. The idea of the driving test was therefore to ensure that all users have the required knowledge for effective use of the consortium’s machines.

Survey for exascale co-design

In a previous post I introduced the European Exascale Software Initiative (EESI) Co-design deliverable in which EPCC is a joint task leader. We are looking to understand exactly what different people mean by the co-design term, what can be done to encourage and promote co-design and - specifically for exascale - how institutions might apply it to successfully deliver the HPC services of tomorrow.

Snow in Denver

It's snowing!

Today is the last day of the exhibition at SC13 so whilst I'm manning the booth (#3932) I thought I'd talk about some of the sessions I've been to and people I've met since my last post.

Addressing gender diversity in STEM: thoughts from the Gender Summit

If you have read any of my previous blogs, you will know that I have an interest in the lack of women working in the field of HPC and Physics. Last week I was lucky to be able to attend the third international Gender Summit in Washington DC, which aims to address, discuss and share ideas on how to improve the participation of women in science, technology, engineering and mathematics (STEM).

EPCC hosts three supercomputers in the world's top 50!

The most recent top500 list has just been released at SC13 in Denver, and I'm pleased to say that 3 EPCC-hosted systems appear in the top 50:

Energy efficient supercomputing

Today I attended the "First International Workshop on Energy Efficient Supercomputing (E2SC)"

It was really interesting (and confidence boosting) to find that what we are trying to do in the Adept project is similar in approach to that done by other research labs. The talks could be divided into two categories: modelling the effect of system parameters (such as cache) on energy and performance efficiency; and methods for measuring energy consumption.

CP2K user meeting: overcoming the 'complexity hump'

Author: Iain Bethune
Posted: 18 Nov 2013 | 10:20

For the last five years, I've been involved in the development of the CP2K materials science code, mostly in terms of improving its performance and scalability and porting to new systems. During that time a great deal of new functionality has been added, as well as additional input file options, libraries and autotuning capability to enable maximum performance on any given architecture. However, these improvements have come at the cost of increased complexity - and CP2K already has a fearsome reputation among researchers for being very hard to use!

Hello, Denver!

As the title says, "Hello Denver".

This is my first time in Denver and thanks to a grant from UKUSAHPC, I'm attending SC13. Over this next week, I'll  share some insights from SC about what's happening in the area and any especially interesting people I meet.

Data infrastructure: highlights of the EUDAT Conference 2013

EUDAT - the European Data Infrastructure project - has reached the end of its second year and has, with some success, distilled the first version of a common, collaborative, horizontal data infrastructure from among the vertical stacks of its various partners.
