Roncq, Hauts-de-France, France
Member of Center of Excellence at AMD and prepare for current and future GPU technologies.
I am supporting the HPC users of Summit supercomputer and getting ready for the next generation supercomputer, Frontier. I give talks for training purposes with focus on storage and performance analysis as also preparing documentation. My interest focus on identifying performance bottlenecks, I/O issues by using appropriate tools, benchmarking and learn new technologies, providing data transfer guidance and various programming models. I am member of the IO-500 committee, we did achieve #1 position on IO-500 list on November 2018 with Summit and Alpine, a Spectrum-Scale filesystem. I am interested in exploring new technologies and how they could be used on our systems.
I am a computational scientist at the Supercomputing Laboratory of King Abdullah University of Science and Technology (KAUST). Our team supports Shaheen II, a Cray XC-40 supercomputer which was 7th on Top500 list in June 2015. I support the requests about earth science models at KAUST, such as WRF/WRF-CHEM, to be executed efficiently on Shaheen II. I investigate various technologies, such as Intel KNL, NVIDIA GPU, and how to achieve high performance. I am also familiar with programming models such as OpenACC and OmpSs. I lead the Burst Buffer Early User program at KAUST, where the scope is to port many applications on Burst Buffer and improve the I/O performance. I provide advanced support to users, either using profiling tools and optimize code, or apply programming models. Furthermore, through many trainings, I teach efficient programming approaches to the users. I am one of the developers of the IO-500 benchmark which help us to understand better the expected performance of a filesystem.
