Subject: Survey of Freely Available Linear Algebra Software

Survey of Freely Available Linear Algebra Software

I'm updating a survey I did last year on freely available software
for the numerical solution of linear algebra problems.
Of interest is software for high-performance computers
that's available on the web in source form for solving problems
in numerical linear algebra, specifically dense, sparse direct and
iterative systems and sparse iterative eigenvalue problems.
The current list is at:
Please let me know about updates and corrections.
I'll post the updated list in a few weeks.

Subject: OpenGL for Fortran 90

Recently the OpenGL Architecture Review Board approved the Fortran 90
bindings for the OpenGL 2D and 3D graphics library. These bindings are
defined in NISTIR 6134 "A Fortran 90 Interface for OpenGL: Revised
January 1998", which is available at the web site below.

I am pleased to announce the availability of f90gl version 1.1, a public
domain implementation of the OpenGL Fortran 90 bindings. This version
implements the interface for OpenGL 1.1 (or Mesa), GLU 1.2, GLUT 3.6 and
several OpenGL extensions. It supports most Unix workstations and
Windows 95/NT.

OpenGL is a software interface for applications to generate interactive 2D
and 3D computer graphics. OpenGL is designed to be independent of operating
system, window system, and hardware operations, and is supported by many
vendors. The OpenGL Fortran 90 bindings represents a significant development
for scientific visualization in the Fortran community. Until now there has
never been an industry standard for generating graphics from Fortran programs;
instead, only proprietary libraries that support a limited number of systems
have been available. With the new bindings, a Fortran programmer can write
standard-conforming graphics applications that will be portable over most
computing platforms.

More information and the f90gl package are available at the f90gl web page.

Subject: Numerical Integration of Rapid Varying Function

Consider a 3D surface, partitioned into finite elements, let's call "Ek" one
of these elements. The element Ek is defined by 4 point called node, each
node belong to the 3D surface.
Let P=(x[1],x[2],x[3]) be a point belonging to Ek, it means that the
coordinates of "P" in the global cartesian system, can be obtained by the
following coordinate transformation :

x[i]= N(u,v)[j]*x[j][i]

in which:

x[i] cartesian coordinate "i" of P

x[j][i] cartesian coordinate "i" of node "j" j=1,2,3,4

N(u,v)[j] shape function [j] j=1,2,3,4

u surface coordinate -1< u < +1
v surface coordinate -1< v < +1

Let's consider the following arrays

un=[-1,-1,1,1] vn=[-1,1,1,-1]

now, the shape function can be defined as follow:

N(u,v)[j] = 1/4(1 + un[j]*u)*(1+vn[j]*v)

Over this element Ek the following function is to be integrated :

Exp[ I k | Y-X | ]/(4 PI | Y-X | )

in which
k is the wave number
I is the imaginary unit
Y a point that belongs to the element "Ek"
X a point in the three-dimensional space (X can belongs to Ek)
| Y - X | distance between the point Y and X
PI the greek p

Using the foregoing coordinate transformation the integrand become:

Exp[ I k | Y(u,v)-X | ]/(4 PI | Y(u,v)-X| )* | J(u,v) | * d u * d v

in which
| J(u,v) | is the modulus of the vector product of the tangent vectors to
the family of line u=cost and v=cost

Up to now I've been using an iterative subdivision with Gaussian
quadrature formulas for precision purposes and an extrapolation technique
to increase the speed of convergence.

Speed and precision are critical for this application, so any suggestions
to increase one or both will be appreciated and acknowledged.

Subject: International Conference Interval'98

INTERVAL'98, the fourth in a series of biannually
organized conferences, was held in Nanjing, China, April 20-23.
It was attended by more than 30 researchers from 15 different
countries all over the world. The conference was organized by:
* Department of Mathematics, Nanjing University
* The Editorial Board of the International Journal
"Reliable Computing"

Whereas the previous meetings focused on relationships of interval
mathematics to other areas, Interval, 98 having global optimization as
an application area in mind, put strong emphasis on traditional
interval methods. New results on well established methods were
presented, and complexity issues were discussed. Several talks dealt
with new, efficient implementation techniques.

Nevertheless, a number of interesting and surprising applications were
suggested. Take the foundations of physics or a combination of
Western and Oriental medicine as some striking examples.

All in all, there were 31 talks. The refereed proceedings of the
conference will be published as a special issue of the "Reliable
Computing" journal.

The conference took place in the relaxed atmosphere of the Holiday Inn
Hotel and was supported by the national Natural Science Foundation of
China and Nanjing University. The German Research Association (DFG)
supported some of the German participants.

Due to the facilities in the hotel, the everlasting friendliness of
the Chinese organizers, and a very interesting bus excursion to the
touristic highlights of Nanjing, there were lots of possibilities to
establish new scientific contacts or intensify existing ones.
