[Lapack] want the subroutine for Ax=b

I meant: "lapack is not appropriate for 100,000-by-100,000 sparse 
symmetric matrices."

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
this inverse process i have to it for many times.

Do you have any code which solves using parallel computing
