He received his Master in Applied Mathematics and his PhD in Computer Science from the University of Houston in 2008. He joined the National Institute for Computational Science at Oak Ridge National Lab as a computational scientist in December 2009 following a Postdoctoral Position in June 2008 at the University of Tennessee Innovative Computing Laboratory lead by Dr. Jack Dongarra. His expertise areas include performance analysis, tuning and optimization, System Utilization Analysis, Monitoring and Library Tracking Usage, Porting and Optimizing Scientific Applications on Accelerator Architectures (NVIDIA GPUs, Intel Xeon Phi), Linear Algebra, Numerical Analysis and Multicore Algorithms
Dr. Samuel Kortas
For 25 years, Samuel Kortas has been working as a research scientist at the Los Alamos National Laboratory, the French Atomic Commission of Energy, Electricité de France, or as a technical leader at Cap Gemini involved in consulting missions for Hewlett-Packard, Alcatel Lucent, ST MicroElectronics or Lexmark. His missions were related to performance tuning in high performance or embedded computing for domain as diverse as ocean modeling, nuclear safety, telecom services, driver programming, or technical survey and realization of proof of concept on strategic market trends. As a benchmarking expert, Samuel was involved in the procurement and acceptance of five major supercomputers. Since 2013, as a Computational Scientist at the KAUST Supercomputing Core Lab, he is simplifying the use of Shaheen for industrial and academic users. He develops tools extending the scheduler capabilities in managing workflows of thousands of dependent jobs making them fault-tolerant to hardware or numerical failures. Samuel received his engineering degree from the Ecole Centrale Paris in 1992 and his PhD in Applied Mathematics from the University of Marseille in 1997.
