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.
