Spring 1997


IMA Workshop

Parallel Solution of PDE

June 9-13, 1997


Organizers:

Petter Bjørstad (University of Bergen) and Mitchell Luskin (Univ. of Minnesota)

Workshop Schedule

The numerical solution of the partial differential equations of continuum mechanics is of major importance to the development of many technologies and has been the target of much of the development of parallel computer hardware and software. Parallel computers offers the promise of greatly increased performance and the routine calculation of previously intractable problems. This period of concentration and workshop will promote the development and assessment of new approximation and solution techniques which can take advantage of parallel computers. Topics to be the focus of research include sparse matrix techniques, domain decomposition methods, parallel multi-grid methods, and novel time and space discretizations.

Workshop Schedule

All talks are in Lecture Hall EE/CS 3-180 unless otherwise noted.
