* Package name : rocalution Version : 5.3.0 Upstream Author : Advanced Micro Devices, Inc. * URL : https://github.com/ROCmSoftwarePlatform/rocALUTION * License : Expat (MIT/X) Programming Lang: C++ Description : ROCm library for iterative sparse solvers rocALUTION is a library that provides iterative sparse preconditioners and solvers. The rocALUTION project began as a port of PARALUTION to the AMD ROCm platform. As such, it supports an OpenMP backend for multi-core CPUs, a HIP backend for discrete AMD GPUs, and an MPI backend for multi-node clusters and multi-GPU setups. . rocALUTION provides a C++ API containing implementations of fixed-point iteration schemes such as Jacobi iteration and Gauss-Seidel; Krylov subspace methods such as the conjugate gradient method and the biconjugate gradient stabilized method; a mixed-precision defect correction scheme; a Chebyshev iteration scheme; as well as geometric and algebraic multigrid solvers. There are also a wide variety of sparse preconditioners, including several based on matrix splitting schemes, factorization schemes, and approximate inverses. I'm not sure which libraries use rocALUTION. It is one of the few libraries in the ROCm stack that's not a dependency of PyTorch or Tensorflow. However, it is an incredibly useful library nonetheless. These sparse iterative solvers are commonly used in Eulerian fluid simulations for the pressure solve. The pressure solve is typically the slowest part of an incompressible fluid simulation and rocALUTION provides highly optimized and parallelized implementations, enabling much larger simulations than could be run on a single machine. Long ago, I implemented some of these algorithms myself and it took me weeks. Even then, my implementation didn't nearly approach the quality of rocALUTION. (There's probably lots of other uses for rocALUTION, but I did my M.Sc. on fluid sims so that's what I know.) This package is part of AMD's ROCm stack and will be maintained under the Debian AI team umbrella.
