Pre-exascale Architectures: OpenPOWER Performance and Usability Assessment for French Scientific Community

In this video from the NVIDIA GPU Technology Conference, Gabriel Hautreux from GENCI presents: Pre-exascale Architectures: OpenPOWER Performance and Usability Assessment for French Scientific Community.

“In order to prepare the scientific communities, GENCI and its partners have set up a technology watch group and lead collaborations with vendors, relying on HPC experts and early adopted HPC solutions. The two main objectives are providing guidance and prepare the scientific communities to challenges of exascale architectures. The talk will present the OpenPOWER platform bought by GENCI and provided to the scientific community. Then, it will present the first results obtained on the platform for a set of about 15 applications using all the solutions provided to the users (CUDA,OpenACC,OpenMP,…). Finally, a presentation about one specific application will be made regarding its porting effort and techniques used for GPUs with both OpenACC and OpenMP.”

Gabriel Hautreux is an HPC Engineer at GENCI. Since its creation in 2007 by the Public authorities, GENCI is working to increase the use of numerical simulation and high performance computing (HPC) for boosting competitiveness within the French economy, across all scientific and industrial fields. GENCI’s role is to implement the national strategy for equiping in HPC resources the three national computing centres and making the systems available for French researchers; to support the creation of an integrated European high performance computing ecosystem; to work to promote numerical simulation and high performance computing within the academic and industrial communities.
