Biography: Dr. Houssain Kettani received the Bachelor's degree in electrical and electronic engineering from Eastern Mediterranean University, Famagusta, North Cyprus, in 1998, and Master’s and doctorate degrees both in electrical engineering from the University of Wisconsin, Madison, Wisconsin, USA, in 2000 and 2002, respectively. He joined as faculty member the department of electrical and computer engineering at the University of South Alabama, Mobile, Alabama, USA in 2002-2003, then department of computer science at Jackson State University, Jackson, Mississippi, USA in 2003-2007, and department electrical and computer engineering and computer science at Polytechnic University, San Juan, Puerto Rico, USA in 2007-2012 where he also was director of partnership development office. He joined Fort Hays State University, Hays, Kansas, USA in 2012, and is currently professor and director of computer science and information systems engineering. Dr. Kettani has served as Staff Research Assistant at Los Alamos National Laboratory, Los Alamos, New Mexico, USA in summer of 2000, Visiting Research Professor at Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA in summers of 2005 to 2011, Visiting Research Professor at the Arctic Region Supercomputing Center at the University of Alaska, Fairbanks, Alaska, USA in summer of 2008, and Visiting Professor at the Joint Institute for Computational Sciences at the University of Tennessee, Knoxville, Tennessee, USA in summer of 2010. Dr. Kettani’s research interests include computational science and engineering, high performance computing algorithms, information retrieval, network traffic characterization, number theory, robust control and optimization, and Muslim population studies. He presented his research in over sixty refereed conference and journal publications and his work received over four hundred citations by researchers all over the world. He chaired over hundred international conferences throughout the world and successfully secured external funding of more than a million dollars for research and education from US federal agencies such as NSF, DOE, DOD and NRC.
Title of Speech: Advances in High Performance Computing and Impact on Societies
Abstract: In the past thirty years, advances in high performance computing have increased the performance by million times, and decreased the volume of the machine by similar order. Accordingly, the fastest computer in the world increased its performance from one Gigaflop/s in mid-1980s to a projected one Exaflop/s by 2020. In addition, current hand-held devices such as smartphones have performance that rivals those machines of the 1980s. Due to hardware limitations, parallel computing became an integral part of our lives that it is hard to imagine a device that is not using multiprocessor power, including smartphones. What started as a hardware solution to physical limitation, prompted software engineers to adopt to parallelism, which also motivates the theoretical solution to algorithms design and analysis to provide a solution that is parallel oriented rather than a serial oriented one. This in turn allows the use of more data points and more simulation trials to improve Monte Carlo simulations for better accuracy and smoother results. On the other hand, the increased computing power also means an increase in the efficiency of brute force attack algorithms on encryption standards, which will make the widely adopted Advanced Encryption Standard obsolete by the end of this century. However, as we move towards exascale computing and beyond, we need to keep in mind that the power of humanity is not in the powerful machines we develop, but remains in our intelligence and ability to develop solutions to problems at the basic level.
