On 27 September 2023 at 11:00 CEST, the EuroCC2 is organizing a webinar on NekRS Spectral Element as a part of the Industrial Code of the Month series of events.
The Nek project, developed at MIT in the mid-1980s, aimed to combine the speed and efficiency of spectral methods with the geometric flexibility of finite elements. The initial version of Nekton, named Nekton 2.0, was the first commercial CFD software designed for distributed memory parallel computers. It was marketed by Nektonics and later by Fluent during the mid-90s. The research version, also known as nek5000, was awarded the 1999 Gordon Bell Prize.
Nowadays, the code is open source, and it boasts state-of-the-art, scalable algorithms that are fast and efficient on various platforms, from laptops to the world's fastest computers. The software has many applications, including fluid flow, thermal convection, combustion, and magnetohydrodynamics, which are used in various fields. The user community comprises over 500 scientists and engineers from academia, laboratories, and industries.
This webinar focuses on the newest version, nekRS, targeting accelerators. It presents the basic concepts of the Nek project and highlights recent large-scale applications. nek5000/nekRS can easily be used (even at scale), for example, as part of the Jupyter-CoEC computing service hosted at the Jülich Supercomputing Centre. This will be demonstrated in the last part of the presentation.
