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.

Primer on Programming in Python and Mathematical/Computational Techniques for Scientists and Engineers

PRISM Co-PI Prof Matt Piggott from the Department of Earth Science and Engineering, Imperial College London’s was involved in preparation of Primer on Programming in Python and Mathematical/Computational Techniques for Scientists and Engineers.

The primer is (currently) split into four sections:

PyFR Seminar Series

The series comprises invited talks on a range of topics related to the theory of high-order Flux Reconstruction schemes, their implementation in the PyFR (www.pyfr.org) flow solver, and their application to industrially relevant flow problems. The overarching objective of the series is to help bridge the gap between academic research activities and real-world industrial requirements.

 

PyFR v1.15.0 released

PyFR 1.15.0:

  • Improved performance and scaling of CUDA backend.
  • Improved performance across all backends via revised GiMMiK kernels.
  • Support for detecting load imbalances for multi-rank simulations.
  • Support for heterogeneous CPUs in the OpenMP backend.
A quick remidner PyFR v1.14.0 was released in May 2022  pyfr.org

Nektar++ 5.2.0 Released

The latest version of Nektar++, v5.2.0, was released on the 23rd August 2022.

This release includes a range of new features and improvements over the 5.1.0 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.

Computer Physics Communications Seminar

The Nektar++ team recently gave an online seminar as part of the Computer Physics Communications seminar series. This is available to watch here.

From Zero to Devito with Dr. Rhodri Nelson

Devito is a domain specific language (DSL) and compiler for finite difference schemes. Built on top SymPy, the DSL allows users to express PDE boundary value problems in a few lines of Python code. This workshop will provide attendees with an introduction to the core elements of the Devito DSL with a focus on modelling seismic wave-propagation.

A breakdown of the agenda is as follows:

  • Introduction to the DSL
  • Expressing PDEs in Devito
  • Introduction to Devito operators
  • Building wave-propagators
  • Full waveform inversion with Devito

Instructors

  • Rhodri Nelson – Devito
