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.

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.

With my Software Sustainability Institute hat on, I recently participated in a back-to-back Data Carpentry and Software Carpentry course sponsored by the University's Research Data Service here at the University of Edinburgh. The courses were held in the main University library in a gorgeous room with a glass wall, providing a rather distracting view of the Meadows parkland.

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?

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.

A consortium of Europe’s leading supercomputing centres and HPC experts is developing the Fortissimo Marketplace, a one-stop-shop where end-users will access modelling and simulation services, plus high-performance data analytics.

Last week we held the 3rd annual CP2K users group meeting down at Kings College London. Amazingly, we are already half-way through the 5-year 'CP2K-UK' project - the EPSRC-funded community support effort that I'm leading - how time flies! It was great to see these meetings continue to go from strength to strength. This year we had over 50 people there on the day from around the UK but also a significant proportion from overseas too! While the primary aim of our activities is to support the UK research community, if we have a wider impact that's of course a bonus.

Or why debugging is hard and parallel debugging doubly so
Debugging programs is hard. I give a lecture on debugging for the Programming Skills module of EPCC's MScs in HPC and HPC with Data Science where we try to point out common programming mistakes, programming strategies for making bugs less likely, and the skills and tools required for investigating, identifying, and fixing bugs.
