GPU-Based Parallel Nonlinear Conjugate Gradient Algorithms
In this paper we describe some parallel algorithms for solving nonlinear systems using CUDA (Compute Unified Device Architecture) over a GPU (Graphics Processing Unit). The proposed algorithms are based on both the Fletcher-Reeves version of the nonlinear conjugate gradient method and a polynomial preconditioner type based on block two-stage methods. Several strategies of parallelization and di...
متن کاملOpen Problems in Nonlinear Conjugate Gradient Algorithms for Unconstrained Optimization
The paper presents some open problems associated to the nonlinear conjugate gradient algorithms for unconstrained optimization. Mainly, these problems refer to the initial direction, the conjugacy condition, the step length computation, new formula for conjugate gradient parameter computation based on function’s values, the influence of accuracy of line search procedure, how we can take the pro...
متن کاملImplementation of Conjugate Gradient Algorithms
We evaluate the High-Performance Fortran (HPF) language for the compact expression and eecient implementation of conjugate gradient iterative matrix-solvers on High Performance Computing and Communi-cations(HPCC) platforms. We discuss the use of intrinsic functions, data distribution directives and explicitly parallel constructs to optimize performance by minimizing communications requirements ...

متن کاملA Three-terms Conjugate Gradient Algorithm for Solving Large-Scale Systems of Nonlinear Equations
Nonlinear conjugate gradient method is well known in solving large-scale unconstrained optimization problems due to it’s low storage requirement and simple to implement. Research activities on it’s application to handle higher dimensional systems of nonlinear equations are just beginning. This paper presents a Threeterm Conjugate Gradient algorithm for solving Large-Scale systems of nonlinear e...
