The Engineering and Physical Sciences Research Council (EPSRC) has just launched six new High Performance Computational (HPC) Centres, worth a combined £20 million, at the Thinktank Science museum in Birmingham. These new Tier2 regional centres are aimed at supporting both academics and industry providing access to a diverse range of powerful supercomputers for scientific research and engineering.

These Tier2 systems will sit between the National Tier1 (e.g. ARCHER) and local campus Tier3 systems (e.g. Balena), addressing the gap in capability between these two levels. This new layer of Tier2 HPC will enable new discoveries and drive innovation, it will be open to any UK ESPRC researcher and provide easy local access, and be integrated with the HPC ecosystem across the UK, both vertically into Tier1 and Tier3 systems and horizontally to other Tier2 centres.  The Tier2 Centres will provide access to new and advanced technologies such as Intel’s Knights Landing (KNL) Xeon Phi, NVIDIAs Pascal, POWER8, 64-bit ARM and data burst buffers. To complement this minefield of diverse technologies, all six Centres will provide support though Research Software Engineers (RSEs) to assist with the training and skills development, porting and optimisation of applications and codes.

 

Great Western 4 (GW4) HPC Centre for Advanced Architectures: Isambard
Isambard, after Victorian engineer Isambard Kingdom Brunel, will be the first of its kind 64-bit ARM-based supercomputer providing multiple advanced architectures within the same system to enable evaluation and comparison across a diverse range of hardware platforms in a production environment. This is a joint project between the GW4 Alliance (universities of Bath, Bristol, Cardiff and Exeter) together with Cray Inc. and the Met Office. The service will provide over 10,000 high performance ARMv8 cores, as well as NVIDIA P100 and Intel Xeon Phi (KNL) accelerators cards.

Who are your customers and mine?

  

📥  Business Support Systems, Computing Services, Research, Service Desk

I often hear colleagues talking about 'our customers' and 'customer service', but who ARE our customers, yours and mine?

Thinking of the University as a whole, it might be easiest to start with the obvious ones: undergraduate and postgraduate students who want us to educate them and prepare them for their chosen destination. That's a reasonable start, but our customers include a MUCH wider range of people and organisations than just our students.

A Customer is anyone who wants or needs something from you.

That may sound like a very broad definition, but let me put that in context:

The parents and grandparents of our students want to be sure that their children are going to get an excellent education, have a good experience while at university and that their investment is good value.

Our research partners want to be sure that we are capable of carrying out excellent research and that we will deliver appropriate results within the budgets and timescales set. Employers want us to create educated, qualified, job-ready graduates who will add value to their organisations as soon as they are employed. Funding bodies want us to to be deserving of the money they give us, delivering proven results in education and research. The public expects us to use their money wisely and to push the boundaries of research for the betterment of mankind.

Those are our external customers, but we also have internal customers, all of whom expect and deserve a high level of service and support. Our managers need us to do our jobs efficiently and to quickly report problems so that they can be addressed before they escalate; colleagues need us to perform our functions well and to support them when they want something else from us.

You need me to do the best I can for you and I need you to do the same for me.

So again I ask, who are your customers?

 

Until next time.

 

Mathematicians use Balena to model global air pollution

Dr Gavin Shaddick, of the University of Bath’s Department of Mathematical Sciences and Deputy Director of the Bath Institute for Mathematical Innovation, has been leading an international research team, which includes the WHO, and have used the University of Bath's High Performance Computing (HPC) system, Balena, to investigate global air pollution.

The results show that nine out of ten people (92 per cent) on Earth live in places where air pollution is higher than acceptable limits – even when they are outside.

HPC for researchers by Tobias Brewer

  , , , , , , ,

📥  High Performance Computing (HPC), Research

The annual symposium at Bath brings together people from across the University to discuss how they use High Performance Computing (HPC) in their research. This year, the event included talks from several departments as well as keynote speakers from Intel and Cardiff University. People with projects from many diverse research areas attended and presented their work on topics such as data sharing in biology, computational screening of inorganic materials and topological optimization. All of these projects benefit hugely from HPC.

My PhD research centres around the efficient simulation of rare events and determining the probability of their occurrence. How likely is it that a tsunami will strike this coastal city? What was the probability of this genetic mutation? Could this village be destroyed by a lava flow? To answer questions like these requires computer codes that concurrently simulate a very large number of sophisticated systems. The C++ program's that perform these simulations take a ludicrously long time to run. The University's HPC computing system, Balena, allows these computations to be sped up dramatically, often by a factor of more than 20. This makes it simpler to consider more sophisticated systems and to perform analysis of much rarer events. A simulation that would have otherwise taken a month to run now takes less than two days.

Furthermore, with Balena facilitating the execution of several codes simultaneously, researchers can obtain results from many different simulations at the same time. Balena has a huge amount of software and hardware available for researchers to employ: various compilers, a SLURM scheduler and MPI libraries for parallelizing code. Of particular use to my research are the Allinea profiling tools which make it easy to identify bottlenecks and bugs and to pinpoint memory leaks. The system also enables the use of accelerator cards, such as the Intel Xeon Phi's, which can reduce computation time even further. I'd encourage any researcher at Bath to utilise Balena for its wide range of computational tools and for the considerable amount of time that it can save you in your research.

Attendees of the 5th HPC Symposium

We would like to thank everyone who joined us at the 5th Annual Bath HPC Symposium yesterday. Following the trend from previous years, the event was a great success for the University.

This year represented the fifth symposium and the event was attended by over 50 participants from within the university, collaborators, as well as external partners including Intel. The schedule for the day included contributions from across the University: physics, maths, chemistry, biology; mech-eng, elec-eng and chem-eng; management and architecture. These contributions showcased the sheer variety of innovative HPC work being done across the University, covering including molecular dynamics and quantum-chemical simulations through to high level finite-element methods to solve engineering problems. The Symposium provided a great opportunity for networking and for learning about new developments in hardware, software and applications.

We would like to say a big thankyou to the contributors, attendees, keynote speakers, session chairs and ground crew, who together made this meeting a day to remember.

Also, we would like to congratulate our two prize winners, Tobias Brewer and Will Saunders, once again for their outstanding poster presentation and contributed talk.

5th Annual HPC Symposium - Keynote Speakers

  , , , , , , , , , , , , , , , ,

📥  High Performance Computing (HPC), Research

We are pleased to announce two keynote talks for the upcoming 5th Annual Bath HPC Symposium on Thursday 9th June.

The first keynote will be given by Dr Tom Connor from Cardiff University, titled "The Cloud Infrastructure for Microbial Bioinformatics (CLIMB); overcoming barriers to software use and data sharing in biology".

Genome sequencing has made it possible to examine fundamental biological questions over vast scales; from bacteria to man. Since the first bacterial genome was published 20 years ago, research focused around bacterial pathogens has been at the very vanguard of the revolution that has transformed biology into a data rich, data intensive field of science. Thomas will discuss how cloud approaches are being used in the MRC’s £8.5m CLIMB project to overcome key challenges that exist for most biologists today.

The second keynote will be delivered by Andy Mallinson from Intel. Andy will give us an overview of the Xeon Phi (MIC) architecture, some tips and tricks for developing, optimising and porting HPC codes to use them, a glimpse of Intel's future roadmap and the benefit these development will have for next-generation HPC systems.

We would like to take this opportunity to remind those who have not yet registered to do so, and to encourage participants to submit an abstract for a contributed talk or poster on their research.

Registration is currently open at https://bathhpc-2016.eventbrite.co.uk (deadline: Friday 27th May), and information about abstract submission can be found on the symposium website at http://go.bath.ac.uk/hpc-symposium (deadline: today, Friday 13th May).

We will be in touch again with further updates soon.

Best wishes,
Jonathan and Steven
