Success Story: Running AVBP Industrial code on Arm architectures

With the diversification of the micro-processor catalogue for High-Performance systems, porting and evaluating software performance on Arm-based architectures has become an imperative step for code developers. For core performance to multi-node scalability, real application benchmarks remain elusive. Given the myriad of Arm flavours available, a comprehensive real case benchmark would give developers and users a first look for the future usage of the European Processor Initiative (EPI) and Arm-based leadership class systems.
In collaboration with Arm Ltd., CERFACS has performed a first benchmark using the AVBP code, a state-of-the-art Navier Stokes solver on unstructured grids for reactive compressible flows written in Fortran and based on MPI for parallelism.

On the technical debt of high-performance scientific software

High-performance scientific software must overcome two specific challenges: scientific validation, and performance on bleeding-edge and short-lived hardware. Success in each requires time, expertise, and cumulative experience over many failed attempts. Thus, engineering software developers are mostly experts in physical modelling or in high-performance computing (HPC) and rarely experts in the management of technical debt.

Key points and take-outs from the FORTRAN webinar organised by EXCELLERAT

The EXCELLERAT Centre of Excellence held a Webinar with Wadud Miah on the topic “Fortran for High Performance Computing” on the 4th of May 2021. Following this event, CERFACS created a COOP blog article with the objective to further share the answers to the questions discussed during the webinar with the HPC ecosystem.

EXCELLERAT’s Fourth All-Hands Meeting

From 30 November to 1 December 2021, our project meeting was once again hosted as a digital event due to the continuing pandemic situation. About 30 partner representatives per day presented the EXCELLERAT project tasks’ good progress, some minor 2021 challenges, and the requirements for the project’s extension and great final results.
