P Arallelslicot Model Reduction Routines: the Cholesky Factor of Grammians
نویسنده
چکیده
This paper presents part of the work being carried out to obtain parallel versions of the main SLICOT routines for model reduction. It is focused on the parallel solution of standard Ly apunov equations obtaining the Cholesky factor of the con trollabilit yand observabilit y Grammians. This operation is an important basis for model reduction methods. Routines from the standard libraries BLAS, LAPA CK,SLICOT, PBLAS and ScaLAPA CKha vebeen used whenever possible in the parallelisation process. How ev er, ithas been necessary to dev elopsome new routines. Experimental results obtained using a cluster of PC's are shown.

Accuracy-enhancing methods for balancing-related frequency-weighted model and controller reduction
We consider the solution of the balancing-related frequency-weighted model and controller reduction problems using accuracy enhanced numerical algorithms. We propose /rst new stability-enforcing choices of the frequency-weighted grammians which can guarantee the stability of reduced models for two-sided frequency weights. Then we show that for the frequency-weighted controller reduction problem...
متن کاملCoprime Factor Reduction of H∞ Controllers
We consider the efficient solution of the coprime factorization based H∞ controller approximation problems by using frequency-weighted balancing related model reduction approaches. It is shown that for a class of frequency-weighted performance preserving coprime factor reduction as well as for a relative error coprime factor reduction method, the computation of the frequency-weighted controllab...
متن کاملAccuracy enhancing methods for the frequency-weighted balancing related model reduction
In this paper we develop computational techniques with enhanced accuracy for two frequency-weighted model reduction approaches, namely, balanced truncation, and singular perturbation approximation. New stability-enforcing choices of the frequency-weighted grammians can guarantee the stability of reduced models for two-sided frequency weights. Several numerical examples show the effectiveness of...
متن کاملThe design and implementation of the parallel out-of-core ScaLAPACK LU, QR, and Cholesky factorization routines
This paper describes the design and implementation of three core factorization routines—LU, QR, and Cholesky—included in the out-of-core extension of ScaLAPACK. These routines allow the factorization and solution of a dense system that is too large to fit entirely in physical memory. The full matrix is stored on disk and the factorization routines transfer sub-matrice panels into memory. The ‘l...
