EE 598: ELECTRICAL ENGINEERING RESEARCH SEMINAR COURSE #9

Speaker: Robert F. Lucas, Information Sciences Institute (ISI) and USC Viterbi School of Engineering

Talk Title: Multifrontal Factorization on Heterogeneous Multicore Systems

Series: EE598 Seminar Course

Abstract: When solving the sparse linear systems that arise in mechanical computer aided engineering (MCAE), and other applications, the multifrontal method is particularly attractive as it transforms the sparse matrix factorization into an elimination tree of dense matrix factorizations. The vast majority of the floating point operations can be performed with calls to highly tuned BLAS3 routines, and near peak throughput is expected. Such computations are performed today on clusters of multicore microprocessors, often accelerated by by graphics processing units (GPUs). This talk discusses how concurrency in the multifrontal computation is processed with message passing (MPI), shared memory (OpenMP), and GPU accelerators (CUDA), exploiting the unique strengths of each.

Biography: Dr. Robert F. Lucas is the Director of Computational Sciences at the University of Southern California's Information Sciences Institute (ISI) and a Research Associate Professor in Computer Science at the Viterbi School of Engineering, University of Southern California. At ISI he manages research in computer architecture, VLSI, compilers, and adiabatic quantum computing. Prior to joining ISI, he was the Head of the High Performance Computing Research Department in the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. Prior to joining NERSC, Dr. Lucas was the Deputy Director of DARPA's Information Technology Office. He also served as DARPA's Program Manager for Scalable Computing Systems and Data-Intensive Computing. From 1988 to 1998 he was a member of the research staff of the Institute for Defense Analyses's Center for Computing Sciences. From 1979 to 1984 he was a member of the Technical Staff of the Hughes Aircraft Company. Dr. Lucas received his BS, MS, and PhD degrees in Electrical Engineering from Stanford University in 1980, 1983, and 1988 respectively.
