Cineca

PETSc č una libreria software nota ai ricercatori computazionali per la sua flessibilitā d'uso ed estendibilitā. Venerdi' 22 alle ore 11 la dr.ssa Hong Zhang una delle principali sviluppatrici della libreria PETSc, afferente al Computer Science Department Illinois Institute of Technology e Argonne National Laboratory, negli Stati Uniti, terrā al CINECA un seminario su "Portable, Extensible Toolkit for Scientific Computation". La partecipazione č gratuita, č consigliata la registrazione.

Abstract del seminario:Portable, Extensible Toolkit for Scientific Computation (PETSc)

Portable, Extensible Toolkit for Scientific Computation (PETSc) is a suite of data structures and routines for the scalable (parallel) solution of scientific applications. Over many years of research, the developers of PETSc have devised a powerful general-purpose infrastructure for the solution of sparse linear and non-linear systems arising from the discretization of PDEs. Due to its solid mathematical grounding, careful software design, and most importantly, evolution resulting from the usage of many users on various application areas, PETSc has had a major impact throughout the scientific and engineering computing community.

As a PETSc developer, I will give an overview of the PETSc, and demonstrate its uses in algorithmic research, numerical production simulation and parallel performance evaluation. Using several examples, I will illustrate how to define and solve linear and nonlinear equations under PETSc environment. I will also present a list of our ongoing research developments, including the projects on parallel nonlinear implicit coupling solvers for a plasma simulation and composite solvers for electrical power systems.
