http://nanohub.org/resources/23534
This talk describes two First-order System Least-squares (FOSLS) formulations of the nonlinear Stokes flow used to model glaciers and ice sheets. The first is a Stress formulation and the second a Stress-Vorticity formulation. Both use fluidity, which is the reciprocal of viscosity and avoid the...http://nanohub.org/resources/23534noJeffrey AllenSun, 07 Feb 2016 14:05:25 +0000[Illinois] Non-Blocking Conjugate Gradient Methods for Extreme Scale Computing
http://nanohub.org/resources/23536
Many scientific and engineering applications use Krylov subspace methods to solve large systems of linear equations. For extreme scale parallel computing systems, the dot products in these methods (implemented using allreduce operations in MPI) can limit performance because they are a...http://nanohub.org/resources/23536noPaul EllerSun, 07 Feb 2016 14:05:25 +0000[Illinois] Reducing Communication Costs for Sparse Matrix Multiplication within Algebraic Multigrid
http://nanohub.org/resources/23538
Recent years have seen renewed interest in the numerical solution of the Stokes Equations. Of particular interest is the use of inf-sup stable pairs of finite elements for which weak enforcement of the incompressibility condition implies strong enforcement as well, such as with BDMelements....http://nanohub.org/resources/23538noThomas BensonSun, 07 Feb 2016 14:05:25 +0000[Illinois] Range Decomposition: A Low Communication Algorithm for Solving PDEs on Massively Parallel Machines
http://nanohub.org/resources/23540
The Range Decomposition (RD) algorithm uses nested iteration and adaptive mesh refinement locally before performing a global communication step. Only several such steps are observed to be necessary before reaching a solution within a small multiple of discretization error. The target application...http://nanohub.org/resources/23540noTom ManteuffelSun, 07 Feb 2016 14:05:25 +0000[Illinois] Multigrid Methods Conference

http://nanohub.org/resources/23478
Efforts are currently being directed towards a fully implicit, electromagnetic, JFNK-based solver, motivating the necessity of developing a fluid-based, electromagnetic, preconditioning strategy [1]. The two-fluid plasma (TFP) model is an ideal approximation to the kinetic Jacobian. The TFP...http://nanohub.org/resources/23478noChristopher LeibsThu, 04 Feb 2016 19:22:38 +0000[Illinois] A Multigrid Method for the Self-Adjoint Angular Flux Form of the Radiation-Transport Equation Based on Cellwise Block Jacobi Iteration
http://nanohub.org/resources/23481
Cellwise block Jacobi iteration is a technique for radiation-transport calculations in which the angular flux for all directions is solved for simultaneously within a spatial cell with the angular flux in neighboring cells held fixed. Each step of the iteration then involves the inversion of a...http://nanohub.org/resources/23481noJeffrey DensmoreThu, 04 Feb 2016 19:22:38 +0000[Illinois] Understanding the Propagation of Silent Data Corruption in Algebraic Multigrid
