**Subject: Parallel Grid Transformation Software Sought**

Our group is looking for a parallel library available in the

public domain which can perform transformations between grids

(commonly structured, but possibly unstructured) which are

distributed in different ways over an array of PEs.

In essence the problem is just a parallel matrix-vector product

y=Ax and thus many libraries (e.g., PETSc and P-SPARSLIB) are

candidates. The problem is that x and y can have different

distributions, which are specified by the user before A is read in.

After the determination of the distributions of x and y, the matrix

A should be stored in a format which optimizes the performance of Ax

as best it can, which might be difficult if there is not necessarily

much data locality in A.

Any suggestions and/or pointers would be welcome.

**Subject: Interpolation of 3D Scattered Data**

Hello,

I am looking for a tool to interpolate from 3D points (x,y,z,f(x,y,z))

irregularly spaced to a regular 3D grid.

This kind of tool is largely distributed in 2D in Earth sciences

but difficult to find in 3D. I hope somebody could answer me.

Thanks a lot.

**Subject: New Software for Multicriteria Optimization**

A Matlab 4.2 implementation of Normal-Boundary Intersection (NBI),

a new technique for multicriteria optimization, is available

free of charge from http://www.owlnet.rice.edu/~indra/NBIhomepage.html.

Developed by Indraneel Das and John Dennis in July 1996, NBI has

advantages over existing techniques for generating several

Pareto optimal points. The special parametrization of the Pareto set

introduced by NBI enables it to find a very evenly spread set of

points on the Pareto surface given an even spread of parametric settings,

unlike the method of minimizing linear combinations of objectives.

This uniform spread has been rigorously proved to be

independent of the relative scales of the objective functions. Further

this technique improves on continuation/homotopy-based strategies for

tracing the Pareto curve in that it can easily handle more than two

objectives while retaining the computational efficiency of continuation

methods. Other details can be found in the paper on NBI by Das

and Dennis also available from the web site.

**Subject: New Release of Diffpack Available**

Diffpack is a collection of object-oriented C++ class libraries aimed at

the numerical solution of partial differential equations. The first

public release took place in January 1995 and has since resulted in

wide-spread use. Since then the libraries have been subject to

significant improvements. As a result, the Diffpack Public Access

Release 1.4 is now available. The code can be downloaded from

http://www.oslo.sintef.no/diffpack/pub1.4/

or from Netlib

http://www.netlib.org

(the Netlib mirrors are in the process of being updated).

We encourage current Diffpack users to switch to the new version as the

old 1.0 release will no longer be supported.

As for the 1.0 release, the public access license grants you the right

to use Diffpack for academic purposes, i.e., education and research of

non-commercial character. For commercial licensing please contact

Are.Magnus.Bruaset@math.sintef.no for further information.

We want to take this opportunity to thank everyone that has given

feedback on the first release, and thus helped us develop a more robust

and functional software environment.

Best regards,

Are Magnus Bruaset, Hans Petter Lantangen

and the rest of the Diffpack Development Team

**Subject: SuperLU Version 1.0, Sparse Linear System Solver**

SuperLU Version 1.0 -- Sparse Linear System Solver

SuperLU contains a set of subroutines to solve a sparse, possibly

nonsymmetric, linear system A*X=B. It implements Gaussian elimination with

partial pivoting. The algorithm includes efficient structure-prediction

and memory-locality optimization techniques. An earlier version of the

software was made available to the public a year ago. In this first

official release, we have fixed bugs and added the following functionality.

* Fill-reducing preorderings based on minimum degree.

* Complex arithmetic, in both single and double precision.

The package can be obtained from netlib at the following URL:

http://www.netlib.org/scalapack/prototype

or from the anonymous FTP site at UC Berkeley:

ftp.cs.berkeley.edu : pub/src/lapack/SuperLU

We plan to release the parallel library in the future. The related technical

papers can be found at the following URL:

http://www.cs.berkeley.edu/~xiaoye

SuperLU is joint work of James Demmel, Stan Eisenstat, John Gilbert,

Xiaoye Li, and Joseph Liu.

at the University of Dundee, prior to the 17th Dundee Biennial

Conference on Numerical Analysis. The CLOSING DATE IS FEBRUARY 28th

1997.

Entries for the Eighth Leslie Fox Prize competition are now

requested. Any person who is less than 31 years old on January 1st

1997 and has not already won a first prize is eligible. Each entry

should consist of three copies of a paper, describing some of the

candidate's research, that is suitable for a 40 minute lecture at a

numerical analysis symposium. Whether or not the work has been

published or accepted for publication is irrelevant, but no person may

submit more than one paper. Unsuccessful candidates from previous

competitions are encouraged to enter.

The entries will be considered by an Adjudicating Committee: its

members are Prof. C.T.H. Baker (Manchester), Prof. I.S. Duff (RAL), and

Professor L.N. Trefethen (Cornell). Particular attention will

be given to the originality and quality of each paper, and to the

suitability of the material for a 40 minute talk to a general audience

of numerical analysts. Papers will be selected by the Committee by

the end of March, for presentation at the Leslie Fox Prize meeting.

Only the papers that are presented at the symposium will be eligible

for awards but, subject to this restriction, the Adjudicating Committee

may award any number of first and secondary prizes.

Entries should be received by February 28th, 1997.

Each candidate should include a statement of her/his year of

birth and should indicate that she/he would be available to present

her/his paper at the symposium. A joint paper may be submitted by an

individual candidate if accompanied by a statement from the co-authors

agreeing to the submission and detailing the contribution of the

candidate to the paper. Travel funds are not generally available to

assist candidates who attend the symposium. The receipt of all entries

will be acknowledged. Any question on this notice should be addressed

to a member of the Adjudicating Committee.

TO ENTER:

One printed copy of each entry should be sent by mail to the Chairman:
