In 2014, GENCI set up a French technologyï»¿ watch group that targets the provisioning of test systems, selected as part of the prospective approach among partners from GENCI. This was done in order to prepare scientific communities and users of GENCI's computing resources for the arrival of the next "Exascale" technologies.\nThe talk will present results obtained on the OpenPOWER platform bought by GENCI and open to the scientific community. We will present on the first results obtained for a set of scientific applications using the available environments (CUDA,OpenACC,OpenMP,â¦), along with results obtained for AI applications using IBM's software distribution PowerAI.
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.
