Subject: Seeking Block Toeplitz Examples
I am interested in knowing if there are (and what are) some examples
of differential equations whose discretization requires to solve
linear systems with tridiagonal Toeplitz matrix or block tridiagonal
Toeplitz matrix. In the latter case I need matrices whose the (i,j)-th
block T(i,j) is such that
T(i,i) is a tau (or Toeplitz) matrix;
T(i,i+1) and T(i,i-1) are diagonal matrices;
T(i,j)=0 otherwise.
Thanks in advance for your suggestions.

Subject: New Optimization Code
We would like to announce the availability of a new
code for solving large nonlinear optimization problems
with bounds on the variables.
The program, called L-BFGS-B, implements a limited memory BFGS
algorithm. The user must supply the gradient g of f, but knowledge
about the Hessian matrix is not required. This program is an
extension of algorithm L-BFGS (Harwell routine VA15) which can handle
only unconstrained problems.
Both codes can be obtained via anonymous ftp at eecs.nwu.edu.
They are in the directories pub/lbfgs and pub/lbfgs.unc.

COMPUTING IN HIGH ENERGY PHYSICS
C H E P - 9 5
Rio de Janeiro, September 18 - 22 1995
Computing for the Next Millenium......
The conference will take place from Monday September 18th to Friday
September 22nd. It will be preceeded by a "Workshop and Tutorial Day" on
Sunday September 17th. It will be followed by a 2 or 3 day HEPIX meeting
starting on Monday September 25th. There will be a limited number of talks
in plenary sessions, with a strong focus on hearing from people outside of the
field of High Energy Physics, and a large number of parallel sessions.
The second day of the conference will include special vendor exhibits and
one or more of the parallel sessions devoted to vendor technical presentations.
a) THE PROGRAM
It was always the intention of the conference to include all relevant aspects
of Computing in High Energy Physics - from data acquisition and triggering, to
analysis, simulation, data storage, languages, tools and algorithms, just as
has been done at previous CHEP conferences. To make it quite clear that all areas are to be addressed at this conference we have changed the emphasis and theme of the program to
"Computing for the next Millenium".
Clearly we are at a time in the development of High Energy Physics, when some major changes in the way we think through our data acquisition and computing problems and apply technology to solve them, will be called for in the high energy physics programs of the year 2000 and beyond. We would like papers submitted to this conference to relate to this
issue of "reinventing the model of computing" as we move forward. We ask that they help make this conference one which
looks to the future, rather than the past, by considering how the work they
present relates to Computing for the Next Millenium. We hope, thus, to
maintain our focus on where we are going, whilst entertaining both radical
suggestions and approaches to Computing problems, as well as step-wise
incremental progress which may provide the basis for our future Computing.
Topic areas:
The program is currently envisaged as breaking down into 5 main topic
areas, each of which will have multiple parallel sessions. One or more of the
sessions from each topic area will run in parallel with sessions from other
topic areas. Currently our tentative breakdown into topic areas is
as follows:
A Analysis
B Data Access snd Storage
C DAQ and Triggering
D Worldwide Collaboration
E Tools, Languages, and Software development environments
We will be working with our International Advisory Committee on details of
the program and more details on topic areas and sub-topics will be available
on the web shortly. Authors are requested to attempt to classify their paper
in the most appropriate topic/sub-topic area when submitting.
We will continue to send out Bulletins via EMAIL, but all information on the
program, abstracts and instructions to authors will be kept up to date on
the Web page at Fermilab - http://www-chep95@fnal.gov/
or http://www.lafex.cbpf.br/

Subject: PARA95, ScaLAPACK & PVM NAG Tutorial
PARA95
Tutorial on ScaLAPACK and NAG PVM Library for IBM SP2 & SGI PC
August 21, 1995
(organised by IMM & UNI*C, DTU, 2800 Lyngby, Denmark)
This tutorial will show how to use basic software on two
different distributed memory computers, IBM SP2 with 40
processors and SGI Power Challenge with 16 processors. The
ScaLAPACK and Concurrent NAG Libraries will be discussed. Some
concurrent software for the IBM SP2 and SGI Power Challenge
will be overviewed also.
The name LAPACK is an acronym for Linear Algebra PACKage.
LAPACK can solve systems of linear equations, linear least
squares problems, eigenvalue problems and singular value
problems. LAPACK can also handle many associated computations
such as matrix factorization or estimating condition numbers.
LAPACK routines are written so that as much as possible of the
computation is performed by calls to the Basic Linear Algebra
Subprograms (BLAS). Highly efficient machine-specific
implementations of the BLAS are available for many modern
high-performance computers. The BLAS enable LAPACK routines to
achieve high performance with portable code. LAPACK is designed
to give high efficiency=A0 on vector processors, high-performance
"super-scalar" workstations, and shared memory multiprocessors.
The ScaLAPACK (or Scalable LAPACK)=A0 library includes a subset
of LAPACK routines redesigned for distributed memory parallel
computers. It is currently written in a Single Program Multiple
Data style using explicit message passing for interprocessor
communication. It assumes matrices are laid out in a
two-dimensional block cyclic decomposition. The goal is to have
ScaLAPACK routines resemble their LAPACK equivalents as much as
possible. ScaLAPACK relies on the PBLAS (Parallel Basic Linear
Algebra Subprograms) and the BLACS (Basic Linear Algebra
Communication Subprograms). The PBLAS perform computations
analogous to the BLAS but on matrices distributed across
multiple processors. The PBLAS rely on the communication
protocols of the BLACS. The BLACS are designed for linear
algebra applications and provide portable communication across
a wide variety of distributed-memory architectures.
NAG has launched a new library of numerical routines called
the NAG Numerical PVM library, specifically designed for
distributed memory machines. The library is aimed at users with
computational problems large enough to make efficient use of
the increased processing power and memory capacity of multiple
processors. The Library principally makes use of BLACS for
message passing. The logical topology of the NAG PVM Library is
similar to the logical topology of ScaLAPACK (see above). The
library is organised into chapters, including Quadrature,
Optimization, Linear Algebra, Random Numbers, Input/output and
Utility functions.
This tutorial is intended for people interested in computing
on parallel distributed memory machines. The lecture material
will be based on the IBM SP2 and the SGI Power Challenge
computers. This course will be of benefit to application and
systems developers in the areas of large-scale scientific
computing, heterogeneous systems, and general purpose
concurrent processing.
The lectures assume a general knowledge of parallel
processing, networking and modern numerical analysis.
The lecturers of the tutorial are John Brown, Salvatore
Filippone, Ken McDonald and Antoine Petitet. John Brown is a
senior computer scientist at teh Headquarter of SGI in
California, USA. Salvatore Filippone is a senior computer
scientist at the IBM Research Center in Rome, Italy. Ken
McDonald is a senior computer scientist at the Numerical
Algorithms Group in Oxford, England. Antoine Petitet is a
computer scientist at the University of Tennessee in the Jack
Dongarra Group.
There will be workstations for the ScaLAPACK and the NAG PVM
Library exercises and demonstrations.
The tutorial is organised the day before the Workshop on
Applied Parallel Scientific Computing in Physics, Chemistry and
Engineering Science.
