A Block Preconditioner for an Exact Penalty Formulation for Stationary MHD
The magnetohydrodynamics (MHD) equations are used to model the flow of electrically conducting fluids in such applications as liquid metals and plasmas. This system of non-self adjoint, nonlinear PDEs couples the Navier-Stokes ...
Preconditioning Techniques for Reduced Basis Methods for Parameterized Partial Differential Equations
The reduced basis methodology is an efficient approach to solve parameterized discrete partial differential equations when the solution is needed at many parameter values. An offline step approximates the solution space ...
Recursive computation of spherical harmonic rotation coefficients of large degree
Computation of the spherical harmonic rotation coefficients or elements of Wigner's d-matrix is important in a number of quantum mechanics and mathematical physics applications. Particularly, this is important for the ...
Anomaly Detection for Symbolic Representations
A fully autonomous agent recognizes new problems, explains what causes such problems, and generates its own goals to solve these problems. Our approach to this goal-driven model of autonomy uses a methodology called the ...
A Stochastic Approach to Uncertainty in the Equations of MHD Kinematics
The magnetohydodynamic (MHD) kinematics model describes the electromagnetic behavior of an electrically conducting fluid when its hydrodynamic properties are assumed to be known. In particular, the MHD kinematics equations ...
Studying Directory Access Patterns via Reuse Distance Analysis and Evaluating Their Impact on Multi-Level Directory Caches
The trend for multicore CPUs is towards increasing core count. One of the key limiters to scaling will be the on-chip directory cache. Our work investigates moving portions of the directory away from the cores, perhaps ...
