Success Story: In situ VR visualisation of Nek5000 simulations with Vistle

Nek5000 cases that use Exascale level performance compute data on very large grids. Writing this data to disk frequently becomes a major run time bottleneck, while handling all the data on disk comes with its own challenges. With increasing data sizes and complexity analysing the usually 3D data with conventional 2D methods becomes even harder. Running large simulations is also costly, therefore errors should better be identified rather sooner than later.

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.
