The Team

Last but not least, these systems are supported by an experienced and knowledgeable team of Computational Scientists and System Administrators within the Supercomputing Core Laboratory. The Scientists team is multi-disciplinary and able to support various science areas and bring HPC related expertise to KSL users. Profiles of each team member are detailed as follows:

Dr. Saber Feki

Saber Feki leads the computational scientists team at the KAUST Supercomputing Core Laboratory supporting and training users of the leadership supercomputer Shaheen. He participated in the procurement and led the acceptance of the world's 7th fastest supercomputer, Shaheen XC40. Saber received his MSc and Ph.D. degrees in computer science from the University of Houston in 2008 and 2010, respectively. He then joined the oil and gas company TOTAL in 2011 as an HPC Research Scientist. Saber has been working at KAUST since 2012. His research interests include parallel programming models and automatic performance tuning of MPI communications and OpenACC accelerated applications such as computational electromagnetics and seismic imaging.

Dr. Rooh Khurram

Rooh Khurram is working as a Computational Scientist at Supercomputing Core Lab at KAUST. He has conducted research in finite element methods, high performance computing, multiscale methods, fluid structure interaction, detached eddy simulations, in-flight icing, and computational wind engineering. He has over 15 years of industrial and academic experience in CFD. He specializes in developing custom made computational codes for industrial and academic applications. His industrial collaborators include: Boeing, Bombardier, Bell Helicopter, and Newmerical Technologies Inc. Before joining KAUST in 2012, Rooh worked at the CFD Lab at McGill University and the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. Rooh received his Ph.D. from the University of Illinois at Chicago in 2005. In addition to a Ph.D. in Civil Engineering, Rooh has degrees in Mechanical Engineering, Nuclear Engineering, and Aerospace Engineering.

Dr. Zhiyong Zhu

Zhiyong Zhu received his PhD degree in Condensed Matter Physics from the Institute of Physics, Chinese Academy of Sciences, in 2009. After that, he spent 4 years conducting research in the area of Computational Material Science at KAUST and EPFL. In 2014, he joined KAUST Supercomputing Core Lab as a Computational Scientist to support Quantum Chemistry users on Shaheen. Owing to his 4 years' experience in using supercomputers for research and the knowledge about both computational codes and high performance computing, he has been able to help Shaheen users to use the computational resources more efficiently.

Dr. Bilel Hadri

Bilel Hadri is a Computational Scientist at the Supercomputing Core Lab at KAUST since July 2013. He contributes in benchmarking and performance optimization, helps in systems procurements, upgrades, and provides regular training to users. 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.

Dr. Georgios Markomanolis

George S. Markomanolis is a Computational Scientist at KAUST Supercomputing Core Lab. His research interests are on performance evaluation and optimization of HPC applications with a focus on weather models and support to the users of supercomputers. He is an expert on using many profiling tools, understanding the bottlenecks and propose solutions. He is working on new technologies such as Intel Xeon Phi KNL and he co-organized the KAUST-NVIDIA GPU Hackathon 2017. He leads the Burst Buffer early users program where he explores many methodologies to achieve better I/O performance across various users’ applications. Moreover, he explores task-based programming models and has achieved performance improvements compared to standard programming models. Before joining KAUST, he was a senior engineer at Barcelona Supercomputing Center, at the Earth Sciences Department. He obtained his M.S. in Computational Science from the Department of Informatics and Telecommunication, National and Kapodistrian University of Athens, Greece in 2008 and his Ph.D. in Computer Science from the Ecole Normale Supérieure de Lyon, France in 2014.
