SPIKE algorithm SPIKE algorithm The SPIKE algorithm is a hybrid parallel solver for banded linear systems developed by Eric Polizzi and Ahmed Sameh The SPIKE algorithm deals with a linear system , where is a banded formula_1 matrix of bandwidth much less than formula_2, and is an formula_3 matrix containing formula_4 right-hand sides. It is divided into a preprocessing stage and a postprocessing stage. In the preprocessing stage, the linear system is partitioned into a block tridiagonal form Assume, for the time being, that the diagonal blocks ( with ) are nonsingular. Define a block diagonal matrix then is also nonsingular. Left-multiplying
