ARCHER Champions began with a vision: every research organisation that could benefit from ARCHER should have someone local who knows about the routes to access ARCHER and who can help potential users to get started.

We want Champions to tell us how we can improve support for them and their local users, and how to start joining up all the HPC facilities and the people with the expertise around the UK.

Latest Top500 list, looking beyond the number 1

There's been a lot of discussion about the latest Top500 list, released this week at ISC16.  Most of the interest has been in the whopping new Chinese system, Sunway TaihuLight, which has come in at number 1 on the list with a massive 93 PFlop/s rpeak Linpack performance, and 125 PFlop/s rmax theoretical peak performance (3 times bigger than the previous number 1 system).Top500

Whilst this is a very interesting system, and much bigger than is currently planned elsewhere, it's not unknown for very large systems to come in and dominate the list like this.  Back in 2002, the Japanese Earth Simulator system became the number 1 machine with an rpeak of ~5x that of the previous number 1 system, and it stayed as the top machine for a number of years.

If you're only going to learn one programming language, you should learn...

Choice, choice, choice A Piper

I'm often asked "What programming language should I learn for scientific computing?".  Or I get involved in religious-like discussions about the best programming language for a particular task, or of all time (think Python vs Fortran, Go vs C, etc...). What's my answer?

Just recently I realised that, to me, programming languages are like musical instruments.

Collaboration, collaboration, collaboration

This week sees our annual collaboration workshop with Tsukuba University, Japan (more details are available here).  This is a great chance to get a flavour of the kind of research another HPC centre is undertaking, how they work, and what platforms they are investing in.

The Centre for Computational Sciences (CCS) at Tsukuba is a department very like EPCC, in that it is responsible for high performance and parallel computing at the university, runs and supports large-scale computers for researchers, and undertakes parallel computing research.

Aleksandra Pawlik, former leader of the Software Sustainability Institute’s training activities, shares her thoughts about training aimed at women working in science, technology, engineering and maths (STEM).

Closing the gender gap in STEM is a broad topic. Increasing diversity and female participation at all levels of education and professional world in science and technology is a subject of lots of debates. The Software Sustainability Institute has hosted a series of blog posts on Women in Software. Different perspectives from the authors of these posts show that there are many challenges and many ways they could be addressed.
