... results in efficient schemes for solving large sparse linear systems derived from the discretization of partial differential equations (PDE). Findings – Application of the proposed multigrid methods on two-dimensional boundary value problems is discussed and numerical results are given concerning...

...    thread_pool_queue (function appinv, thread_id n−i) thread_pool_wait where the function appinv(i) computes the i‐th inverted L‐shaped block of the approximate inverse: In this paper, new parallel computational schemes are proposed for the solution of sparse linear systems of the form equation (5...
