Hi, for sparse systems you should use sparse (either direct or
iterative) solvers. Here are a few examples of sparse solvers:
MUMPS,
SuperLU,
Trilinos,
PETSC,
PSBLAS,
PASTIX
Note that Trilinos and PETSC are much more than solvers and also
contain interfaces for all the others.

Hello sir,
please help.
i want the subroutine in fortran 77
to solve the system Ax=B
A is sparse symmetric real matrix
size is around 100000X100000
presently the solver which i am using is taking lot of time to find the
inverse.
this inverse process i have to it for many times.
Do you have any code which solves using parallel computing
presently my os is windows 64 bit
my application is on intel visual fortran using visual studio 2008
please help
?thanks and regards
