We are delighted to announce that new animation explaing “What is Nektar++?” is already available

Nektar++ is an open-source spectral/hp element software framework supporting the development of efficient classical low polynomial order h-type solvers as well as higher p-order piecewise polynomial order solvers. Nektar++ supports the development of high-performance scalable solvers for partial differential equations and offers free access to its detailed user guide, tutorials in different formats and a repository of pre-written solvers

PyFR Seminar Series

Reminder that you can checkout our PyFR Seminar Series on Cassyni.

Firedrake ‘23

The seventh Firedrake user and developer workshop will be held between 13-15 September 2023 at Missenden Abbey. For more information see the workshop page.

Nektar++ 5.3.0 Released

The latest version of Nektar++, v5.3.0, was released on the 25th March 2023.

This release includes a range of new features and improvements over the 5.2.0 release.

A full list of the changes is available in the CHANGELOG.md file distributed with the source code.

As always, if you encounter any problems please feel free to contact us.

Nektar++ Workshop 2023

The 7th annual Nektar++ Workshop will bring together developers and users of all experiences to hear about new and future developments in the Nektar++ spectral/hp element framework and the exciting science and engineering being undertaken with the code.

The three days will include a comprehensive programme of talks and a poster session. The workshop will be run primarily as an in-person event, but the talks will be streamed online. It is hoped we can offer a limited number of remote presentations for those unable to travel.

For more information, visit the Nektar++ Workshop 2023 webpage.

Exascale Computing Challenges: Parallel-in-Time Algorithms

Date and Time:

Monday 9 January 2023, 11:00 – 17:00 GMT

Tuesday 10 January 2023, 09:00 – 17:00 GMT

Wednesday 11 January 2023, 09:00 – 13:00 GMT

Location: Reed Hall, University of Exeter, Streatham Drive, Exeter EX4 4QR

Overview

In this workshop we will focus on time-parallel methods. Following exciting developments in both mathematical analysis and practical experience, time-parallel methods are undergoing a revival as a potentially powerful route to exploiting future massively parallel exascale supercomputers. Time-parallel methods address the question of what to do when one has reached the limits of strong scaling (decreasing wallclock time by increasing the number of processors working in parallel) through domain decomposition parallelisation in space. A key lesson from the recent literature is that the success of parallel-in-time algorithms critically depends on them being carefully adapted to the equation being solved. Much like regular timestepping methods, there are many parallel-in-time algorithms, and the right algorithm needs to be designed and selected according to the mathematical properties and applications requirements of the underlying system.

This workshop will combine lectures with practical demonstrations to introduce timestepping challenges and how to overcome them using time-parallel methods, such as parareal, deferred corrections and paradiag. The practical demonstrations will be based on jupyter notebooks and some experience of using python is desirable.

Format

This event is a workshop funded by the ExCALIBUR project: RSE training in algorithms for exascale simulations.

Speakers include:

  • Dr Jemma Shipton, Lecturer in Mathematics (E&R), University of Exeter
  • Josh Hope-Collins, Research Associate in Computational Mathematics, Faculty of Natural Sciences, Department of Mathematics, Imperial College London
  • Dave Acreman, HPC Applications Analyst, Hewlett Packard Enterprise

Organisers:

  • Dr Jemma Shipton, Lecturer in Mathematics (E&R), University of Exeter
  • Dr Katie Finch, Head of Research Software Engineering and Assistant Director of Research Services, University of Exeter

Refreshments and catering

Refreshments and catering will be served throughout the event. Please do advise of any dietary requirements upon registration.

Congratulations to PRISM team memebers on new grant awards

PRISM team memebers were awarded with the following ExCalibur projects:

  • Prof Kelly is collaborating with colleagues at Edinburgh on  Efficient Cross-Domain DSL Development for Exascale (ukri.org). The project web page is avaiable here:  xDSL
  • PI David Moxey, co-PIs Chris Cantwell and Spencer Sherwin are part of the UKAEA-funded project NEPTUNE (Neutrals & Plasma Turbulence Numerics for the Exascale). The grant itself is £380k (80% FEC) between KCL and ICL;  runs from September 2022 to February 2024.

Firedrake ‘23

The slightly inaccurately named Firedrake ‘22 user and developer workshop will be held at Dartington Hall in Totnes from 4-6 January 2023. The event is cohosted by the University of Exeter and Imperial College London.

The workshop is an opportunity for Firedrake users and developers to engage with each other to communicate the ways that Firedrake can be used in simulation science, the latest developments in the project, and the future developments anticipated. The event provides Firedrake users with the opportunity to interact directly with developers and other users.

Key Dates

  • 18/11/2022 Abstract submission
  • 02/12/2022 Registration
  • 4-6/1/2023 Workshop

The workshop will run from 1400 on 4 January to 1400 on 6 January (after lunch on Wednesday until after lunch on Friday). This will hopefully allow most UK participants to travel to and from the event on those days.

Abstract submission

Abstracts should be submitted via EasyChair by Friday 18 November 2022. We expect to be able to accommodate a talk by any participant who wishes to present their work.

Registration

Click here to register! The registration deadline is 2 December 2022.

Registration will include meals and accommodation and early registration rates will be £150 for students and £250 for others.
