A mixed-precision algorithm for the solution of Lyapunov equations on hybrid CPU–GPU platforms
Elsevier (2011)We describe a hybrid Lyapunov solver based on the matrix sign function, where the intensive parts of the computation are accelerated using a graphics processor (GPU) while executing the remaining operations on a general-purpose ... -
Efficient model order reduction of large-scale systems on multi-core platforms
Springer (2011)We propose an efficient implementation of the Balanced Truncation (BT) method for model order reduction when the state-space matrix is symmetric (positive definite). Most of the computational effort required by this method ... -
Exploiting thread-level parallelism in the iterative solution of sparse linear systems
Elsevier (2011)We investigate the efficient iterative solution of large-scale sparse linear systems on shared-memory multiprocessors. Our parallel approach is based on a multilevel ILU preconditioner which preserves the mathematical ... -
Increasing data locality and introducing Level-3 BLAS in the Neville elimination
Elsevier (2011-12-01)In this paper we present two new algorithmic variants to compute the Neville elimination, with and without pivoting, which improve data locality and cast most of the computations in terms of high-performance Level 3 BLAS. ... -
Using graphics processors to accelerate the computation of the matrix inverse
Springer Verlag (2011)We study the use of massively parallel architectures for computing a matrix inverse. Two different algorithms are reviewed, the traditional approach based on Gaussian elimination and the Gauss-Jordan elimination alternative, ...
