Using FPGAs to model the atmosphere

Author: Nick Brown
Posted: 11 Dec 2019 | 15:54

The Met Office relies on some of the world’s most computationally intensive codes and works to very tight time constraints. It is important to explore and understand any technology that can potentially accelerate its codes, ultimately modelling the atmosphere and forecasting the weather more rapidly.

Field Programmable Gate Arrays (FPGAs) provide a large number of configurable logic blocks sitting within a sea of configurable interconnect. It has recently become easier for developers to convert their algorithms to configure these fundamental components and so execute their HPC codes in hardware rather than software. This has significant potential benefits for both performance and energy usage, but as FPGAs are so different from CPUs or GPUs, a key challenge is how we design our algorithms to leverage them.

PICTURES project: predicting disease with artificial intelligence

EPCC is part of a £4.4 million project to turn a database of millions of clinical images into a powerful research tool to help tackle health conditions including lung cancer and dementia.

Each year millions of clinical images such as X-rays, CT, MRI, ultrasound, nuclear medicine, and retinal images are generated by the NHS in Scotland and stored in the national imaging database. In addition to containing important clinical information, these images also potentially contain a great deal of information about the health of the individual which is not currently made use of in health care.

EPCC’s ARM system: comparing the performance of MPI implementations

MVAPICH is a high performance implementation of MPI. It is specialised for InfiniBand, Omni-Path, Ethernet/iWARP, and RoCE communication technologies, but people generally use the default module loaded on their system. This is important because, as HPC programmers, we often optimise our codes but overlook the potential performance gains of better choice of MPI implementation.

A data-driven approach to public health

EPCC and other partners at the University of Edinburgh have commenced work on a new programme to develop DataLoch, a data repository for all local, regional and national health and social care data for residents of the Edinburgh & South East Scotland region. DataLoch and the associated Data Driven Innovation team will drive research and innovation, improve patient care, and reduce health inequalities across the region.

Cognitive Geology Ltd is an independent technology company based in Edinburgh, UK. It delivers innovative geological modelling software to the oil and gas industry, with the goal of improving efficiency and reducing uncertainty in geological modelling workflows and the business decisions which are based on them. EPCC has worked with the company to investigate ways to reduce large ensembles of geological models while maintaining the range of plausible scenarios described by the set.

HPC-Europa3: “An excellent way to have international collaborations with excellent scientists”

The HPC-Europa3 programme funds collaborative visits of up to three months for researchers at any level, in any discipline, who need access to HPC resources.

HPC-Europa3 has now been welcoming visitors to EPCC – and another eight HPC centres around Europe – for nearly two years. The successful applicants to date are from a total of 43 countries. Priority is given to researchers working in the EU and Associated States, but limited places are available for researchers working elsewhere who can make a strong case for funding. There is a roughly equal split among the visitors between post-graduates, postdocs, and experienced researchers, and a wide variety of disciplines are represented.

We have been pleased to see that, compared to previous programmes, there has been an increase in the participation of female researchers, who have accounted for 23% of successful applications so far.

Festival Mobility: decisions with data

If you’ve lived in Edinburgh during August, you’ve witnessed a city transformed. Together, Edinburgh’s August festivals represent an annual event close to the size of the Olympic Games. It takes a gargantuan effort by everyone involved with running the city and they do a great job. Those of us who live in Edinburgh during Festival time know that, when dealing with so many people, things don’t always work as well as we’d like. Our commutes may be longer. We might have to stand on the train or walk in the bus lane to bypass the crowds. Edinburgh’s festivals are the envy of the world but can make life more difficult for many of it citizens.

The European Centre of Excellence for Engineering Applications

The European Centre of Excellence for Engineering Applications (EXCELLERAT) has spent its first year identifying the major challenges that must be overcome to reach Exascale performance for a set of reference applications.

There are great opportunities for engineering applications in exploiting exascale computing (that is, more than 1018 operations per second). This will be the case not only in academia but also industry: engineering is seen as having the biggest potential for exascale in the industrial field. EXCELLERAT brings together expertise in HPC and engineering software to support the development of applications that can exploit computing capability at this level.
