You heard it here first! Professional opinions and insights from Hartree Centre staff and collaborators as they go about their day helping UK industry to benefit from the adoption and integration of advanced digital technologies.
On 3rd September the peaceful campus of Birmingham University came alive with bubbling groups of research software engineers, talking in excited tones about their latest optimisation tool and favourite python library, as the third annual conference of Research Software Engineers was started!
A real global affair, #RSE18 had 314 delegates from 12 countries. That represents a nearly 50% increase over last year’s attendance and also a 7% increase in women attending compared to 2017.
UK RSE Association is turning into the Society of Research Software Engineering! A legal, independent, professional organisation!
The UK RSE Association has seen significant growth since its inception in 2013, to over 1000 members. The community’s growth has made the informal, volunteer run format unsustainable. The move will enable the society to hold funds, employ staff, and operate as an independent organisation to represent the interests of the RSE community. Visit the RSE website for more information and sign up to receive updates.
The Hartree Centre has a new pocket-sized addition to our data centre! One of our Research Software Engineers, Tim Powell tells us all about it…
HPiC has been created as a host for software demonstrations and for outreach events. It simulates a supercomputer by networking together 20 Raspberry Pi 3 Model B’s, allowing them to communicate and execute parallel programs.
The Raspberry Pi is a low-cost, low-power, single-board computer designed to make computer science more accessible to amateur developers, schools, and developing countries. Released in 2013, Raspberry Pis can be used for a wide range of applications – from robotics, to music streaming, to smart mirrors! The incredibly versatile Raspberry Pi 3 computer has a Quad Core 1.2Ghz ARM processor at its heart, 1GB of RAM, WiFi, Bluetooth capabilities and a whole host of device connectivity via a GPIO connector.
HPiC replicates high performance computing (HPC) techniques and can perform over 1,000 million instructions per second. HPiC has 19 ‘worker’ nodes (1 node = 1 raspberry pi), each with a quad-core ARM processor, resulting in 76 cores to utilise for parallel computing. The remaining node is called the ‘Head Node’ and allows us to interact and submit jobs to the ‘worker’ nodes.
To mark International Women’s Day, Hartree Centre Data Scientist, Simon Goodchild writes a blog post to celebrate the work of a pioneering epidemiologist and doctor Janet Lane-Claypon. At the time of writing the post, Simon was studying medical statistics for the first time as part of a statistical society diploma and was surprised to have not previously heard about a woman who had invented two of the key techniques he was learning about!
How do you know that your treatment actually works?
How do you know whether something in the environment may impact upon your health?
These are some of the most basic and most important questions in medicine and epidemiology. Getting good answers is vital, and nowadays there are established procedures for finding sensible answers. Several of these can be traced back to the under-recognised work of Janet Lane-Claypon in the early part of the 20th century.
The last in a series of blog posts from Dave Cable, Head of Service Operations here at The Hartree Centre summarises the steps we have taken to implement IT Service Management.
In previous posts, I described three key components of ITIL infrastructure which we have implemented at the Hartree Centre – Service Operations, Service Design and Service Transition. These are all inter-dependent and equal in stature. However, there is one further area of ITIL which is slightly different because it underpins all of the above – Continual Service Improvement (CSI). Continuous improvement is vital, because it ensures that processes and functions do not remain static. They develop and improve in response to operational lessons learnt, leading to overall improvements in service quality. Continuous improvement provides a feedback mechanism and tools to incorporate that feedback. It can also work with quality management tools.
ITIL provides two complementary tools to implement CSI – the Deming Cycle, and the Seven-step Improvement Process.
In this post we talk about developing activities for the Hartree Centre work experience programme and what happened when we challenged 6 students to work together to build a 20-node mini super computer.
STFC runs a work experience programme every year with applicants expressing an interest in placements within the centre. Initially, we had a view of taking just one student to join our Future Technologies team but after hearing about other placements, we wanted to move away from the ‘lone student’ experience and offer a group-based opportunity. We hoped that this would show students how we operate here in multi-disciplinary teams working together to solve challenges. As a result, 6 students from local colleges joined us for 2 weeks to find out more about life here at the Hartree Centre.
The third in a series of blog posts from Dave Cable, Head of Service Operations here at The Hartree Centre gives us an introduction to service design, transition, configuration management and change management.
In my previous post, I described the key aspects of the ITIL Service Operation area that we have implemented at the Hartree Centre. In this post, I’ll move on to Service Design and Service Transition.
What is Service Design?
The ITIL area of Service Strategy considers all the business requirements for IT services, and from them constructs a high-level view of the range of services to be offered. Service Design turns this high-level portfolio into a set of service specifications for inclusion in the organisation’s Service Catalogue. It takes account of the requirements for information security, availability and capacity. Service catalogue entries also include details of standard service levels (SLA metrics) and provide, where appropriate, pricing information. Note that non-standard service levels may be negotiated with individual customers.
High Performance Computing (HPC) and High Performance Data Analytics (HPDA) – the provenance of the Hartree Centre – are rapidly expanding areas of importance to academia and industry, with myriad new employment opportunities arising. It is predicted that the gap between supply and demand of skilled staff will continue to grow. Despite the face that women make up 51% of the population, on average only around 15% of people working in IT are women. The proportion working in HPC and HPDA is even less. When taken in conjunction with recent evidence that diverse teams and organisations outperform less diverse competitors, there are sound business reasons why Diversity and Inclusion is a priority, as well as moral and social imperatives.
I am one of the founders of Women in HPC, which was formed in the UK by a small group of women who were interested in exploring the reasons why so few women were working in all areas of High Performance Computing. From small beginnings, it has grown into an organisation and network with global reach, holding programmes of events at the major international supercomputing and IT conferences.
As proud members of the European HPC community, I think it’s safe to say our efforts to achieve a world-class extreme scale, power-efficient and resilient HPC platform are ambitious. We’re working towards a machine that can scale to 100 petaflops.
This three and a half year, 20 million euro Horizon2020 funded project has been designed to answer these challenges:
How do we build an exascale machine within a sensible energy budget?
How do we design something so that we’re not moving huge amounts of data around?
How do we achieve our ambitions cost-effectively?
How do we deal with all of the complexity associated with running applications on a machine of that size?
First of all, it’s important to note here that we’re not going to be starting from scratch. EuroEXA will build on previous projects that have demonstrated smaller elements of our community ambitions. This learning has directed the approach to EuroEXA and Professor John Goodacre based at The University of Manchester is leading the project and has pulled together a consortium of 40 partners industry and academic partners across Europe. Each project partner will play a fundamental role in bringing together key components of this undertaking. We’ll explain the specific role we’ll have here at the Hartree Centre later on.
The second in a series of blog posts from Dave Cable, Head of Service Operations here at The Hartree Centre gives us an introduction to Service Operation, the primary interface for service delivery with customers.
In the first post of this series, I gave a brief description of IT Service Management and the specific implementation we have adopted, known as ITIL. In this post, I describe how we have implemented one function and three key processes from the ITIL area of Service Operation.
What is Service Operation?
Service Operation is the collection of processes and functions that describe how to deliver services to customers at agreed levels.
Why is it important?
Service Operation represents the primary interface for service delivery with customers. As such, it can win or lose business. It also helps the service provider, by providing clear mechanisms for prioritising customer requests for assistance, and tools to identify deep-rooted issues that require additional effort to resolve.
