## Iterative Methods For Solving Linear Systems

### Non-standard Parallel Solution Strategies for Distributed

Sparse solvers for linear systems ALGLIB C++ and C# library. In computational mathematics, an iterative method is a mathematical procedure that uses an initial guess to generate a sequence of improving approximate solutions for a class of problems, in which the n-th approximation is derived from the previous ones.A specific implementation of an iterative method, including the termination criteria, is an algorithm of the iterative method., In numerical linear algebra, the biconjugate gradient stabilized method, often abbreviated as BiCGSTAB, is an iterative method developed by H. A. van der Vorst for the numerical solution of nonsymmetric linear systems.It is a variant of the biconjugate gradient method (BiCG) and has faster and smoother convergence than the original BiCG as well as other variants such as the conjugate gradient.

Templates for Sparse Linear Solvers The Templates for the solution of large sparse linear systems consists of a collection of iterative methods together with a manual for algorithmic choices, instructions, and guidelines .In contrast to the dense matrix case, there is no single iterative method that can solve any given sparse linear system in reasonable time and with reasonable memory In either case, each processor will end up with a set of equations (rows of the linear system) and a vector of the variables associated with these rows. This natural way of distributing a sparse linear system has been adopted by most developers of software for distributed sparse linear systems вЂ¦
