                    - Thursday, November 6, 1986.

Dr.  Peter  Forsyth  of Dynamic Reservoir Systems, Cal-
gary,  Alberta  will  speak on ``Recent Developments in
Iterative Solution of Sparse Matrices''.

TIME:                3:30 PM

ROOM:              MC 6082

ABSTRACT

Preconditioned conjugate gradient methods have recently
become  the preferred method for interative solution of
large  sparse  systems.   This  seminar  will  focus on
incomplete LU (ILU) preconditionings for sparse systems
with  arbitrary  connectivity,  with application to the
non-symmetric, non-diagonally dominant matrices typical
of oil reservoir simulation.  Some practical considera-
tions such as applications on supercomputers (including
some run times on the CRAY) will also be discussed.
