Inria Bordeaux research center, November 4-8, 2019
The school aimed to simulating a geophysical problem and the modeling of seismic wave propagation, from its modeling to its implementation in a high performance computing (HPC) framework. The school offered both plenary courses and hands-on sessions. The hands-on sessions were conducted in the Federative Platform for Research in Computer Science and Mathematics (PlaFRIM) machine.
The first day was dedicated to the modeling of the problem and its discretization using a Discontinuous Galerkin scheme. The following two days were focused on linear algebra for solving large sparse systems. Background on direct, iterative, and hybrid methods for sparse linear systems were discussed and hands-on on related parallel solvers were also proposed. The next day was dedicated to advanced parallelization schemes using task-based paradigms. The usage of StarPU runtime system was proposed. In addition, a particular attention was devoted to the use of parallel profiling and debugging tools. The school was closed with plenary talks which illustrated the usage of such a workflow in an industrial context from people of Total, CEA, and Airbus.
