Does anyone have any experience with the REDUCE package advertised in
the latest SIAM newsletter? The distributor is
Northwest Computer Algor from Calif. This version operates on PC's.
I am particularly interested in how it works on an IBM-PC/AT
  Thank you.   ([email-masked])

Subject: Second International SUPRENUM Colloquium

Second International SUPRENUM Colloquium
========================================

The 2nd International SUPRENUM Colloquium dedicated to "Supercomputing
Based on Multiprocessor Computer Architectures: Current Developments and
Trends" has been held in Bonn, W.Germany, from Sept. 30 to Oct. 2.

On occasion of a first prototypic version of the SUPRENUM multiprocessor
being operational, this colloquium presented the progress made so far 
in the German parallel supercomputer project SUPRENUM  - both in 
hardware and systems software development and in profound application
software (Linear Algebra, PDE, multigrid, CFD, among others). It also
reflected the evolution of the multiprocessor world SUPRENUM finds itself
in.  A number of internationally renowned speakers had been won to cover 
this latter aspect with talks ranging from hardware overviews and 
parallelizing tools to new application algorithms.

More than 150 participants from several countries attended the meeting
which was commonly considered a great success in dissemanating the 
idea of and enforcing the interest in parallel computing. The SUPRENUM
pre-prototype system has been re-installed at the conference location 
so that demonstrations could be run for the interested public.
 
Proceedings of the Colloquium will appear as a special issue of the
journal "Parallel Computing" (guest editor: U. Trottenberg).

Unfortunately we did not announce it in time via nanet - but maybe it is 
still of interest to know what has been. We will try harder next time.

GENERAL ANNOUNCEMENT AND REGISTRATION INFORMATION 
 
Research in linear algebra impacts on many areas of science. Moreover, 
new directions in research are suggested by questions and developments to both
pure and applied mathematics. The rapid development of supercomputers, 
including increasingly available parallel processors, has triggered a new look
at some of the standard computational linear algebra algorithms.  
Opportunities abound for the development of new algorithms which utilize the 
increasing power of machines in order to solve very large linear systems 
problems.  The conference will bring together researchers and practioners from
academic, industrial and government environments in order to promote 
interaction and exchange of ideas and problems in all aspects of linear 
algebra.  The resulting cross-fertilization is expected to lead to solutions 
of currently outstanding problems as well as to the foundation of new problems
that will guide the further development of linear algebra. 
 
Meeting Themes 
 
Large Scale Computing and                   Linear Systems and Control
