iohann.s.titov@gmail.com Ivan S. Titov rocALUTION is the sparse iterative solver layer of the ROCm math stack. It provides Krylov subspace solvers (CG, BiCGStab, GMRES and friends), algebraic and geometric multigrid, and the matching preconditioners, on top of the sparse primitives sci-libs/rocSPARSE supplies. Its backend is selectable at runtime, so the same solver code runs on the GPU through HIP or on the host through OpenMP. Build the multi-node backend, enabling distributed matrices and solvers Build the host backend with OpenMP threading ROCm/rocm-libraries
