A parallel algorithm for solving the partial eigenvalue problemfor block-diagonal bordered matrices

A hybrid algorithm of the iterative method for the solution subspace of a partial generalized eigenvalue problem for symmetric positive definite sparse matrices of block-diagonal structure with bordering on hybrid computers with graphic processors is proposed, efficiency coefficients of the algorithm are obtained, and the algorithm is tested against test and practical problems. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
