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.

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:
