The use of in-situ analysis tools by EXCELLERAT

Paraview-Catalyst is widely used to perform in-situ visualisation, as in the case of OpenFOAM and Code-Saturne. However, one needs An appropriate version of Paraview-Catalyst on the computer system, the code must be instrumented to transfer its data towards Catalyst, and one usually needs a Python script automatically produced by Paraview.

High-performance computing challenge: How can engineers effectively leverage HPC technology?

When developing or improving products, engineers face the challenge of analysing complex simulations to test their designs. High-performance computing (HPC) is used to solve major problems in engineering by performing demanding operations such as simulations relatively quickly. Also, by processing more precise operations, HPC can avoid the errors that might be introduced by humans.

Nek5000 in EXCELLERAT: towards Exascale

One of EXCELLERAT’s tasks is improving Nek5000’s Exascale readiness, particularly for accelerators. We used an OpenACC version of the proxy-app Nekbone and focused on further optimising the small matrix-matrix kernels which constitutes most of the work in the full Nek5000. Tuning the TOpenACC directives improved performance of these kernels by almost a factor of two.
