This article presents a distributed nondominated sorting genetic algorithm II (NSGA‐II) for
optimal seismic retrofit design using buckling restrained braces (BRBs) on a cluster of multi …

Contemporary large-scale Partial Differential Equation (PDE) simulations usually require the
solution of large and sparse linear systems. Moreover, it is often needed to solve these …

Abstract Batched Sparse Linear Algebra has become an emergent processing mode on
modern hardware accelerators based on Graphics Processing Units (GPUs) developed over …

In this work, we present alternative implementations for the Simultaneous‐FETI (S‐FETI)
method. Developed in recent years, this method has shown to be very robust for highly …

This article introduces a robust and affordable method to compute nullspace and
generalized inverse of finite element operators involved in dual domain decomposition …

The goal is to show how to treat singular matrices via kernel detection so that any robust
direct sparse solver for non-singular matrices may be used. This technique applied in the …

A new hybrid algorithm for LDU-factorization for large sparse matrix combining iterative
solver, which can keep the same accuracy as the classical factorization, is proposed. The …

The computation by lower precision arithmetic or mixed precision arithmetic is one of most
hot topics for the latest or the next generation computing system in HPC environment. It is …

ESPRESO is a FEM package that includes a Hybrid Total FETI (HTFETI) linear solver
targeted at solving large scale engineering problems. The scalability of the solver was tested …

In this work new domain decomposition methods and new implementations for existing
methods are developed. A new method based on previous domain decomposition methods …
