**Subject: CBC Radio Quirks and Quarks Quiz**

Readers may be interested in a quiz question that was posed on

CBC Quirks and Quarks Jan 27 1996 as a useful didactic example.

The quiz question concerns summing the harmonic series. While

the author (Maria Klawe of UBC) was clearly thinking of floating

point summation, students today might actually jump towards

symbolic tools (DERIVE, Maple or Mathematica). More details are

in the Web pages starting with

http://macnash.admin.uottawa.ca/qqjn9601.htm

Email comments on this are welcome. There are also text and

Postscript forms available for download by ftp to the same server

(and embedded in the page above).

**Subject: Seeking Parallel Sparse Solvers**

I am studying on a parallel implementation on solving sparse linear system.

I chose to use Newton's Method for solving a nonlinear system for each time

step. So I got a Jacobian matrix which is sparse and penta-diagonal.

I want to solve the sparse penta-diagonal linear system

J*X=B

with a direct method or iterative method.

I use IBM SP2(distributed memory multiprocessor) machine with

MPI(Message Passing Inteface) or HPF. If you have any idea or code for my

problem, please let me know.

Thank you

**Subject: Flow of Water Through a Porous Medium**

A professor of geology here is interested

in mathematical models and computational methods/software

that may solve his problem. He gave me the problem description:

I wish to use the Navier-Stokes equations or some

simplification of them to determine the flow of

water through a porous medium under steady-state

conditions for an arbitrary, but known, pore structure.

Flow is assumed to be laminar for the range of

conditions of interest.

Boundary conditions include

(1) velocity is 0 at pore boundaries

(2) pressure is known along two parallel planes

perpendicular to the main direction of flow.

I do not wish to model the overall average flow field

but the flow through individual pores and the variation

of velocity within individual pores.

Any reference would be helpful.

Thanks.

**Subject: New Address for Horst Simon and Positions at NERSC**

I would like to inform the NA community that I have accepted a

new position at Lawrence Berkeley National Laboratory as

director of the NERSC Division. As you may have heard, the Department

of Energy has decided to relocate the NERSC supercomputer center from

Livermore to Berkeley. This decision is documented in

http://www.nersc.gov/doc/Whats_New/decisiondoc.html

and general information about NERSC can be found at

http://www.nersc.gov/

NERSC will run in the near future a 512 processor Cray T3E as well as a

cluster of Cray J90 machines and move the Cray C90 from Livermore to

Berkeley. I am very excited to be in the middle of the re-creation of a

supercomputer center. In particular I am looking forward to the increased

interaction with the UC Berkeley computer science and applications community.

There are many job openings at NERSC, and they are listed at

http://ux9.lbl.gov/LBL-Documents/CJOs/

Please take a look and bring them to the attention of students or others

interested in helping to build the new NERSC.

**Subject: Density of States of a Hamiltonian system**

Hello!

I have a small question for people who have experience in

calculating the eigenvalues of extremely large matrices

viz. of the order of 50000 times 50000.

I am interested in evaluating the Density of States (DOS)

of this matrix (real and symmetric). Therefore I would like

to evaluate all the eigenvalues of this matrix.

I would appreciate any references or any programs available

in the NET that does evaluate the above.

Thanks in advance.

**Subject: Reprinting of Brenan, Campbell and Petzold DAE Book**

Our book on the numerical solution of differential algebraic equations

is being reprinted by SIAM: Some of the developments since the first

edition are addressed in the new Chapter 7 and its supplementary

bibliography.

Numerical Solution of Initial-Value Problems in Differential-Algebraic

Equations

K.E. Brenan, S.L. Campbell, and L.R. Petzold

Series: Classics in Applied Mathematics 14

Many physical problems are most naturally described by systems of

differential and algebraic equations. This book describes some of the

places where differential-algebraic equations (DAE's) occur. The basic

mathematical theory for these equations is developed and numerical methods

are presented and analyzed. Examples drawn from a variety of applications

are used to motivate and illustrate the concepts and techniques.

This classic edition, originally published in 1989, develops guidelines for

choosing different numerical methods. It discusses DAE codes, including the

popular DASSL code. An extensive discussion of backward differentiation

formulas details why they have emerged as the most popular and best

understood class of linear multistep methods for DAE's. New to this

edition is a chapter that brings the discussion of DAE software up to date.

The objective of this monograph is to advance and consolidate the existing

research results for the numerical solution of DAE's. The authors present

results on the analysis of numerical methods, and also show how these

results are relevant for the solution of problems from applications. They

develop guidelines for problem formulation and effective use of the

available mathematical software and provide extensive references for

further study.

It will focus on some of the tools that have been developed recently in various

areas of applied mathematics that promise to affect the way we do things in the

next decade. One example is the strengthening interface of mathematicians with

computers and a "nonlinear" version of the steepest descents and stationary

phase methods of asymptotics. Other areas that will be emphasized include

control theory, dynamical systems, stochastic processes and geometric design.

The deadline for submission of contributed abstracts has been extended to

APRIL 15, 1996. Send now your 75-word abstract to meetings@siam.org. Accepted

**Subject: BLAS Technical Forum**

We are organizing a workshop on February 19th and 20th, 1996 in

Nashville to begin a forum for parallel and sparse BLAS.

This will be a follow-up to the discussions that took place

on November 13th and 14th when 52 people attended a Workshop on

Parallel BLAS and Related Interfaces at the University of Tennessee,

and the Birds Of a Feather session that took place at the San Diego

Supercomputer 95 meeting in December.

The existing BLAS have proven to be very effective in assisting portable,

efficient software for sequential and some of the current class

of high-performance computers. We would like to investigate the

possibility of extending these standards to provide greater coverage

of sparse matrices and provide additional facilities for parallel computing.

The purposes of this meeting is to review the findings of the Workshop

in November and the BOF at the Supercomputer 95 conference; and to

begin a forum to develop calling sequences for a set of low-level

computational kernels for the parallel and sequential settings,

as well as standards for basic matrix data structures, both dense and sparse.

For background information see:

http://www.netlib.org/utk/papers/sblas-meeting.html.

For additional information see:

http://www.netlib.org/utk/papers/blast-forum.html.

Workshop Format:

We will start the meeting at 12:00 noon on Monday, February 19th

and plan to finish around 4:00 pm on Tuesday, February 20th.

If you are planning to attend please let me know (dongarra@cs.utk.edu)

as I will be sending a follow-up message with further details.

Future Plans:

For future planning here is a tentative list of dates, roughly 6 weeks apart,

for the forum.
