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