Extreme-scale precision imaging in radio astronomy

Author: Adrian Jackson
Posted: 3 Dec 2020 | 10:00

EPCC has embarked on a new collaboration with Prof. Yves Wiaux (Heriot-Watt University) to advance algorithms for high-precision and high-sensitivity computational imaging. 

The EIRA (Extreme-Scale Precision Imaging in Radio Astronomy) collaboration will focus on radio astronomy, which uses radio telescopes to collect data. This allows observation of the sky with antennae arrays at otherwise inaccessible angular resolutions and sensitivities. Algorithms being developed at Heriot-Watt University will address the challenges of building images from these incomplete linear data sets.

Exploring Fujitsu’s A64FX CPU

The release of Fujitsu’s A64FX CPU has been a high point in an otherwise disappointing year. This next-generation CPU is the brain in Fugaku, the supercomputer at RIKEN in Japan, which was number one in the June 2020 TOP500 list.

Since February, Fujitsu has given EPCC access to a development A64FX machine as part of an early-access programme. We have been exploring the performance of this technology applied to numerous HPC workloads.

EuroCC: a new network of national HPC competence centres

EuroCC will raise participating countries to a common high level in high-performance computing (HPC), high-performance data analytics (HPDA), and artificial intelligence (AI).

National Competence Centres (NCCs) will be responsible for surveying and documenting the core HPC, HPDA, and AI activities and expertise in each participating country. The ultimate goal is to make HPC available to different users from science, industry, public administration, and society.

Exploring Nekbone on FPGAs at SC20

Friday 13 November, 11:05–11:35 am ET

This Friday I am presenting work on accelerating Nekbone on FPGAs at the SC20 H2RC workshop. This is driven by our involvement in the EXCELLERAT CoE, which is looking to port specific engineering codes to future exascale machines.

One technology of interest is that of FPGAs, and a question for us was whether porting the most computationally intensive kernel to FPGAs and enabling the continuing streaming of data could provide performance and/or energy benefits against a modern CPU and GPU. We are focusing on the AX kernel, which applies the Poisson operator, and accounts for approximately 75% of the overall code runtime.

EPCC passes ISO 27001 Information Security and ISO 9001 Quality audits

I am delighted to announce that EPCC has passed our annual external ISO 27001 Information Security and ISO 9001 Quality audits with flying colours. 

EPCC recognises the importance of a process-led approach to the delivery of National Tier-1 and Tier-2 services such as ARCHER, ARCHER2 and Cirrus. The implementation of an ISO 9001-based Quality Management Systems has provided a framework to ensure that the services delivered meet user and customer requirements. It requires that service improvements are identified and the impacts of their implementation tracked, ensuring that the improvement is effective.

UrgentHPC20 workshop at SC: Fighting disasters with urgent computing

Join the workshop: Friday 13 November, 2:30pm–6:30pm ET

At SC20 this year we are chairing UrgentHPC, the second international workshop on the use of HPC for urgent decision making. The idea of the workshop is to explore the fusion of HPC, big data, and other technologies in responding to disasters such as global pandemics, wildfires, hurricanes, extreme flooding, earthquakes, tsunamis, winter weather conditions, and accidents. Whilst HPC has a long history of simulating disasters, we believe that technological advances are creating exciting new opportunities to support emergency, urgent, decision making in real-time.

The 9th Workshop on Python for High-Performance and Scientific Computing (PyHPC) at SC20 will once again bring researchers and developers together to share their experiences of using Python across a wide range of disciplines and applications.

EPCC is a member of the PyHPC Organizing Committee and this year we are co-chairing PyHPC's 9th Workshop on Python for High-Performance and Scientific Computing at SC20 on Friday 13 Nov, 10:00–18:30 EST

HPC-Europa3 Transnational Access Meeting (TAM2020)

The HPC-Europa3 Transnational Access programme funds short collaborative research visits for computational scientists working in any discipline which can use HPC.

Former HPC-Europa visitors are invited to attend the Transnational Access Meeting (TAM), to present the results of their visits. With approximately 40% of visitors being postgraduates, for many it also provides a supportive environment for their first conference presentation.

Urgent computing: presentations at SC20

EPCC leads a work package of the VESTEC (Visual Exploration and Sampling Toolkit for Extreme Computing) project, which seeks to fuse HPC and real-time data for urgent decision-making for disaster response. Our work has resulted in two accepted papers into SC20 workshops: one around our custom workflow execution system, and another on extending the Common Workflow Language standard to better support parallel application execution.

Our support for industry

EPCC continues to support industry in these challenging times, leveraging our three key foundations:

  • The hosting, provision and management of high-performance computing (HPC) and data facilities for academia and business.
  • Research and project support to optimise the computing activities of those organisations.
  • Our unique project-based Applications Group, which provides bespoke novel and high-performance software solutions to academia, industry and commerce.
