    The numerical stability analysis of pipelined conjugate gradient methods: historical context and methodology

  • Original language description

    Algebraic solvers based on preconditioned Krylov subspace methods are among the most powerful tools for large-scale numerical computations in applied mathematics, sciences, technology, as well as in emerging applications in social sciences. As the name suggests, Krylov subspace methods can be viewed as a sequence of projections onto nested subspaces of increasing dimension. They are therefore by their nature implemented as synchronized recurrences. This is the fundamental obstacle to efficient parallel implementation. Standard approaches to overcoming this obstacle described in the literature involve reducing the number of global synchronization points and increasing parallelism in performing arithmetic operations within individual iterations. One such approach, employed by the so-called pipelined Krylov subspace methods, involves overlapping the global communication needed for computing inner products with local arithmetic computations.
