Scientific Applications towards Exascale

The general topic of the first one-and-a-half days will be HPC scientific applications on new computing architectures with a specific focus on the Intel Xeon Phi Knight's Landing processor (KNL).  This will prepare potential users for the KNL-based PRACE-PCP machine to be installed at CINES by that time. The last day will be dedicated to a hands-on session on this machine, where participants will be able to try porting their code and make first performance and energy measurements

Registration is free but mandatory. You can register here until September 18th 2017.

EoCoE is a European Horizon 2020 funded project of Centre of Excellence in computing applications. It is designed to enhance numerical simulation efficiency in the international context of the High Performance Computing (HPC) challenges. It focusses its application scope towards low carbon energy domains.
