Solving large, sparse, linear systems of equations is a fundamental problems in large scale scientific and engineering computation. A model of a general class of asynchronous, iterative solution methods for linear systems is developed. In the model, the system is solved by creating several ...
White paper describing how to use the cuSPARSE and cuBLAS libraries to achieve a 2x speedup over CPU in the incomplete-LU and Cholesky preconditioned iterative methods.
Sparse linear systemsIterative solversWe introduce a systematic analysis in order to fuse CUDA kernels arising in efficient iterative methods for the solution of sparse linear systems. Our procedure characterizes the input and output vectors of these methods, combining this information together with a ...

Systolic algorithms for preconditioned iterative procedures are described and discussed in relation to existing systolic arrays for iterative methods applied to the systems of linear equations arising from the solution of partial differential equations. In boundary value problems it is shown that if the ...
