Order (N) Sparse Banded Linear Solver

[Dr. Timothy Stitt]

Dear PETSc Community,

I was wondering if anyone knew of any sparse/dense banded linear solvers 
that run in order (N)? Does PETSc provide such a solver or link to an 
appropriate external solver? There seems to be a lot of links online to 
theoretical approaches but we are having difficulties in sourcing an 
implementation? I am hoping PETSc might be our saviour ???

Thanks in advance,

Tim.
