BootCMatchG: An adaptive Algebraic MultiGrid linear solver for GPUs

D'Ambra P ; Bernaschi M ; Pasquini D

Sparse solvers are one of the building blocks of any technology for reliable and high-performance scientific and engineering computing. In this paper we present a software package which implements an efficient multigrid sparse solver running on Graphics Processing Units. The package is a branch of a wider initiative of software development for sparse Linear Algebra computations on emergent HPC architectures involving a large research group working in many application projects over the last ten years.
