Subject: Mode Matching Code

I have written a mode matching code that computes the scattering matrices
(S11, S12, S21, S22) of a _rectangular_ _waveguide_ _cross-section_ _jump_.
No assumptions as to symmetry have been made, provided that the cross-section
of the smaller guide lies within the boundaries of the bigger one.

The program is written in f77 and assumes that one has the LAPACK
compiled as library, as well as the BLAS (preferrably machine-BLAS). I have
used the cpp (C preprocessor) to make automatic conversion of declarations,
generic functions and LAPACK/BLAS-names to double precision. e.g. CGETRS ->
ZGETRS. It has been fairly well tested so far; we've calculated filters and
accelerator sections with it.

Anyone interrested send a mail to the address below and I'll be happy to
send the code. BTW, it comes as UNIX shell archive (shar).

Cheers, Bengt (email:

Subject: Query about Fortran 90 to C Translation

Dear Members of Na-net,
I would like to know if there is a Fortran -> C Translator, which is suitable
for use with Fortran90. I know that also the F90 compilers can do this.
The reason why I would like to know this is because we are using Linux
for the program development. Up to now netlibs f2c worked very well,
(as a preprocessor for the Gnu C Compiler) but it does not support F90.
Unfortunately we do not have a F90 compiler running under Linux, but we would
like to write programs in F90.
Any hints and suggestions are very welcome.

I would appreciate pointers to materials that describe the
SPEC benchmarks, available to me via anonymous ftp, gopher,

Subject: Software for Partitioning Graphs


Many problems which arise in the course of scientific computing can be
conveniently described in terms of graph partitioning. A prominent
example is the problem of decomposing a large, unstructured grid across
the processors of a parallel computer. Other applications include generating
nested dissection orderings for sparse matrix factorizations and devising
efficient circuit layouts.

We have developed a software package called "Chaco" which implements a
variety of graph partitioning algorithms. These include the spectral
bisection, quadrisection and octasection algorithms, the inertial method,
the Kernighan-Lin method, and a multilevel partitioner. Techniques can
mixed and matched as well, for example Kernighan-Lin can be applied to
refine a spectral partitioning.

A user's guide and papers describing the algorithms are available by
anonymous ftp to in the directory pub/tech_reports/bahendr.
The software can be obtained at no charge under a research license agreement
and may also be licensed for commercial application. Interested parties
should contact one of the authors at the addresses given below.

Subject: A Matrix Eigenvalue Problem

The following eigenvalue problem was sent to me by Professor J. Luttinger,
a theoretical physicist at Columbia. Please send your responses to Professor
Luttinger at the e-mail address given at the end of his msg.

The problem is concerned with the representation of the largest
eigenvalue of a class of matrices. They are all symmetric and positive in the
sense of Perron. The largest eigenvalue is represented as an integral (from
zero to $2\pi$) of the log of a trigonometric polynomial. Here are a couple
that are fairly easy to work out:

1) The matrix is 2x2,

$$M_2 = \pmatrix{e^k&e^{-k}\cr e^{-k}&e^k \cr}\ , {\rm k}\ real}$$

The result is $2 log {\lambda_m\over 2} = {1\over 2\pi}
\int_0^{2\pi} d\theta log (cosh 2k + sinh 2k\ cos\ \theta).\ \ \lambda_m$ is
the largest eigenvalue of $M_2.$

2) This matrix is 4x4:

$$M_4 = \pmatrix{e^{2(k_1+k_2)}&e^{-k_1}&e^{-2k_2}&e^{k_1}\cr
e^{k_1}&e^{-2(k_1+k_2)}&e^{-k_1}&e^{2k_2}\cr}, k_i\ real}.$$

The result is

$$log {\lambda_m\over 4} = {1\over 2\pi} \int_0^{2\pi} d\theta log(cosh(2k_1)
cosh(2k_2) + sinh(2k_1) cos\theta + sinh(2k_2) cos2\theta).

(The largest eigenvalue of $m_4$ is again given by $\lambda_m.)$

There are other problems of the same general class, but with matrices
that get larger and larger. If done directly they involve seemingly hopeless
amounts of algebra, and yet I have reason to believe that a fairly simple
closed form exists.

Subject: Computational Fluid Dynamics Lectures in Belgium

21-25 MARCH, 1994

The aim of this annual lecture series is to provide in-depth presentations
on well-established methods and on recent advances in the field of numerical
flow simulation. The program is at a specialist level complementary to the
Introduction to Computational Fluid Dynamics (Lecture Series No. 2).

This year the course will recognize the 25th anniversary of the VKI lecture
series in CFD by focusing on the key algorithmic achievements of the past 25
years which constitute the basis of modern CFD for aerodynamic flows today :
shock capturing TVD high resolution schemes for compressible flows, multigrid
acceleration techniques, advances in linear algebra (Generalized Minimum
Residual and Related Methods), unstructured grid methods and solution
adaptivity. Key scientists at the origin of some of the most successful methods
have been asked to review the lessons learned form the past, in order to
determine the important area's where future developments will take place.

With respect to high resolution shock capturing space discretization, both
finite volume methods, cell vertex residual distribution schemes and SUPG
finite element discretizations will be reviewed, emphasizing the different
nonlinear mechanisms in the schemes which allow for monotonic discontinuity
capturing. For application to systems of hyperbolic equations, both the
classical Riemann solver flux difference splitting approach and the more recent
multidimensional flux balance splitting methods will be discussed.

The second subject will be on fast iterative solvers for efficient steady
state computation. Both Krylov subspace methods and multigrid methods will
receive considerable attention, with application to flow problems on structured
as well as unstructured grids.

In addition to these two major subjects, attention will be given to a new
development of non-dissipative numerical schemes suitable for aeroacoustics.

Lectures will be given in English and printed notes will be distributed
to participants at registration on the first day.

The speakers include:

N. Kroll, DLR, Germany.
T.J. Barth, NASA Ames Research Center, California, USA.
P.L. Roe, U. Michigan, Ann Arbor, USA
R. Radespiel, DLR, Germany.

Subject: NASA Workshop on Parallel Numerical Algorithms

ICASE/NASA Langley Workshop on Parallel Numerical Algorithms, 23-25 May 94

To acquaint developers of high-performance applications codes based on
partial differential equations or integral equations with the state of
the art in core areas of algorithms and the parallel computational
environment, and to engage representative experts from the algorithms
community in discussions about their applicability.

A principal parallel challenge in large computational fluid dynamics,
computational structural mechanics, and computational electricity and
magnetism problems is the implicit solution process. Hence, these
applications areas meet in a common algorithmic core. However, results
on model problems are often not transferable. The workshop will promote
more useful development and more rapid integration of parallel
algorithms in high-performance NASA-related applications.

Subject: High-Precision Unconstrained Minimization

Can you recommend a means to solve an unconstrained minimization
problem to high precision?

For our application, in order to achieve adequate precision in the
final solution we need the calculation to be performed in at least
32 decimal digits of precision.

We have double precision Fortran routines for the objective
function, gradient, and Hessian. We have access to several brands
of workstation: Sun, DEC, and SGI. We also have access to
Mathematica and Maple.

Any suggestions would be greatly appreciated.
