Cooperative concurrent asynchronous computation of the solution of symmetric linear systems

Bhaya, Amit; Bliman, Pierre-Alexandre; Pazos, Fernando
2017-07

This paper extends the idea of Brezinski's hybrid acceleration procedure, for the solution of a system of linear equations with a symmetric coefficient matrix of dimension n, to a new context called cooperative computation, ...
A cooperative conjugate gradient method for linear systems permitting efficient multi-thread implementation

Bhaya, Amit; Bliman, Pierre-Alexandre; Niedu, Guilherme; Pazos, Fernando
2018

This paper revisits, in a multi-thread context, the so-called multi-parameter or block conjugate gradient (B-CG)methods, first proposed as sequential algorithms by O’Leary and Brezinski, for the solution of the linear ...
