Hierarchical Techniques in Scientific Computing

Dr. Vivek Sarin

Dr. Sarin received his Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign in 1997. He spent two years as a Research Associate in the Department of Computer Science at Purdue University before joining Texas A&M in Fall 1999. Dr. Sarin's research interests include parallel algorithms and architectures, numerical algorithms, and their application to scientific and engineering disciplines.

Hierarchical approaches have made a profound impact on a number of problems in scientific computing. Notable amongst these are multilevel approaches for partial differential equations (PDEs) and fast methods for n-body simulations. This talk will focus on the solution of linear systems of equations arising from the discretization of PDEs. We will present recent work on novel hierarchical techniques developed for fluid simulations. These techniques have been very effective for large scale simulations of fluid-particle mixtures. In addition to such algorithmic innovations, however, one must address software design issues for high performance computing. We will discuss a number of challenges in high performance scientific computing including software design, parallel computing, visualization, and data analysis.

Everyone is invited and welcome to attend the seminars in this series.
