Dr. Joseph W.H. Liu, York University, will speak on
``Recent Advances in the Multifrontal Method''.
TIME: 1:30 PM
ROOM: DC 1304
ABSTRACT
The multifrontal method is an important advance in
direct methods for solving large sparse matrix linear
systems. The scheme has been recognized as appropriate
for solving sparse problems on different machine
architectures: virtual memory machines, vector and
parallel machines. An overview of the basic
multifrontal method is first presented. Recent
techniques used in the improvements to the scheme are
then described. Experimental results are provided to
demonstrate the practical significance of these
improvement techniques, and to compare the performance
of the multifrontal method with other existing solution
methods.
