SCHOOL ON COMPUTATIONAL FLUID DYNAMICS & SUPER COMPUTING

The School aims at sharing models and numerical methods used by the state-of-the-art CFD research and industrial codes running on High Performance Computing (HPC) clusters, relying on the expertise of internationally recognized scholars and HPC specialists.

The lectures will present challenges involved with solving nonlinear PDEs in problems related to fluid dynamics, using state-of-the-art algorithms. Efficient implementation on massively parallel clusters will be especially targeted.

The lectures will provide a step-by-step didactic introduction to the numerical methods, each lecture being followed by tutorial, hands-on sessions dedicated to efficient parallel implementation.

Introductory and advanced notions about parallelization strategies (MPI, OpenMPI), use of Graphic Accelerators, as well as plug-in numerical libraries, will also be provided. 

Skills:

At the end of the course, the student will possess and know how to use the following skills: Numerical analysis, Algorithms for PDE Solution, HPC architecture

Target audience:

MSc/PhD students, Post-Docs,  Academic and industrial researchers, software developers  which use / are planning to use / develop a code for CFD

 

Pre-requisites:

Basic/intermediate knowledge about parallel computing, numerical analysis and algorithms for PDE solution.  Academic and industrial researchers, software developers  which use / are planning to use / develop a code for CFD
