SPOOLES is a library for solving sparse real and complex linear
|
|
systems of equations, written in the C language using object oriented
|
|
design. At present, there is the following functionality:
|
|
1. Compute multiple minimum degree, generalized nested dissection and
|
|
multisection orderings of matrices with symmetric structure.
|
|
2. Factor and solve square linear systems of equations with symmetric
|
|
structure, with or without pivoting for stability. The
|
|
factorization can be symmetric LDLT, Hermitian LDLH, or
|
|
nonsymmetric LDU. A direct factorization or a drop tolerance
|
|
factorization can be computed. The factors and solve can be done
|
|
in serial mode, multithreaded with Solaris or POSIX threads, or
|
|
with MPI.
|
|
3. Factor and solve overdetermined full rank systems of equations
|
|
using a multifrontal QR factorization, in serial or using POSIX
|
|
threads.
|
|
4. Solve square linear systems using a variety of Krylov iterative
|
|
methods. The preconditioner is a drop tolerance factorization,
|
|
with or without pivoting for stability.
