This training will present basic elements to enable developpers to understand when and how to optimize the performance of their codes.
- Compiler options
- Vectorization – Data access (cache usage maximization)
- Theory to upper-bound the expected performance benefit (speedup, efficiency, peak, memory bandwidth, …)
- Examples of Stencil codes and N-body simulations
Half of the course will be made of hands-on sessions. The hands-on will use the https://github.com/aff3ct/MIPP library
- Bertrand Cirou
- Mathieu Cloirec
- Cédric Jourdain
