The extended unsymmetric frontal solution for multiple-point constraints Authors

Abstract

The purpose of this paper is to discuss the linear solution of equality constrained problems by using the Frontal solution method without explicit assembling. Design/methodology/approach–Re-written frontal solution method with a priori pivot and front sequence. OpenMP parallelization, nearly linear (in elimination and substitution) up to 40 threads. Constraints enforced at the local assembling stage. Findings–When compared with both standard sparse solvers and classical frontal implementations, memory ...
