Summer of HPC visitor Tomislav Subic writes about his introduction to Edinburgh and EPCC.
“It’s gonna be cold and rainining up there the whole time…”
If I got a pound every time I heard that in the last months, I could buy a kilt (which are not cheap by the way). While most of my fellow SoHPCers are fleeing the north in order to spend their summer on the sunny Mediterranean beaches, I am doing the opposite.

Initial experiences on early KNL
Updated 1st August 2016 to add a sentence describing the MPI configurations of the benchmarks run.
Updated 30th August 2016 to add CASTEP performance numbers on Broadwell with some discussion
KNL is a many-core processor, successor to the KNC, that has up to 72 cores, each of which can run 4 threads, and 16 GB of high bandwidth memory stacked directly on to the chip.

Over the last 10 years, the growth in performance of HPC systems has come largely from increasing core counts, which poses a question of application developers and users – how to best make use of the parallelism on offer?

The PRACE Summer of HPC programme offers summer placements at HPC centres across Europe for up to 20 top European applicants. Participants spend July and August working on a visualisation or video related to PRACE technical or industrial work.

Modern genome-sequencing technologies are easily capable of producing data volumes that can swamp a genetic researcher’s existing computing infrastructure. EPCC is working with the breeding company Aviagen to build a system that allows such researchers to scale up their data infrastructures to handle these increases in volume without compromising their analytical pipelines.

Safe havens allow data from electronic records to be used to support research when it is not practicable to obtain individual patient consent while protecting patient identity and privacy. EPCC is now the operator of the new NHS National Services Scotland (NSS) national safe haven in collaboration with the Farr Institute of Health Informatics Research which provides the infrastructure.

This week I have been at the FEAT (Future Emerging Art and Technology) workshop in Vienna, which aims to promote collaboration between scientists and artists. As I am sure many people will be aware, the EU-funded Future and Emerging Technology (FET) programme consists of scientific projects looking to push the boundaries of research in specific fields.

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.

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).
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.

Choice, choice, choice
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.
