HIFOO: a MATLAB package for H-infinity Fixed Order Optimization

HIFOO is a new MATLAB package aimed at solving fixed-order

stabilization and local optimization problems. It depends on a new

hybrid algorithm for nonsmooth, nonconvex optimization based on

several techniques, namely quasi-Newton updating, bundling and

gradient sampling. The user may request HIFOO to optimize one of

several objectives, including H-infinity norm, which requires either

the Control System Toolbox for MATLAB or, for much better performance,

the LINORM function in the SLICOT package. No other external package

is required, but the quadratic programming code QUADPROG from either

MOSEK or the Optimization Toolbox for MATLAB is recommended. Numerical

experiments on benchmark problem instances from the COMPLIB database

indicate that HIFOO could be an efficient and reliable computer-aided

control system design (CACSD) tool, with a potential for realistic

industrial applications.

**Subject: In Berkeley U. did Velvel Kahan a floating standard tome decree**

Many of you are probably aware of Coleridge's poem:

In Xanadu did Kubla Khan

A stately pleasure-dome decree :

Where Alph, the sacred river, ran

Through caverns measureless to man

Down to a sunless sea.

What is less known is his keen interest in accurate

floating point arithemtic. Later on in the poem,

he waxes eloquent about "floating midway on the

waves", clearly revealing an interest in floating

point accuracy when computing with wavelets as well.

Here is the variant on his poem on the IEEE Floating Point Standard:

In Berkeley U. did Velvel Kahan

A floating standard tome decree :

Where Inf, the underflow, and NaN

Threw 'xceptions measureless to man

To C++ and C.

(Another installment in honor of Gene Golub's

request to liven up the NA Digest. If this is too lively,

feel free to beg me to stop. Your request will be duly noted).

**Subject: Postdoc position in Scientific Grid Computing at INRIA Sophia Antipolis**

Postdoctoral project at INRIA Sophia Antipolis

Hierarchical mesh partitioning for parallel scientific computing on a Grid

Grid computing is currently the subject of a lot of research activities

world-wide. Most of these activities aim at providing the necessary tools for

dealing with aspects such as administration, security, performance simulation,

discovery, scheduling and volatility of resources, etc. Few studies are

centred on applications. Computational grids are particularly well suited to

compute intensive, embarrassingly parallel applications. The situation is less

clear for non- embarrassingly parallel scientific computing applications such

as those involving the numerical resolution of system of Partial Differential

Equations using mesh based (finite difference, finite volume or finite

element) methods. The standard parallelization strategy for mesh based

numerical solvers for the solution of systems of PDEs combines a partitioning

of the computational mesh with a message passing programming model. In most

cases, grid-enabled numerical simulation tools are essentially a direct

porting of parallel software previously developed for clusters of PCs or

parallel supercomputers, thanks to the availability of appropriate MPI

implementations such as MPICH-G2. Moreover, these grid-enabled simulation

software rarely take into account important architectural issues

characterizing computational grids, such as heterogeneity both of processing

nodes and interconnection networks, that greatly impact the parallel

performances.

The DiscoGrid project

(http://www-sop.inria.fr/caiman/personnel/Stephane.Lanteri/DiscoGrid/) aims at

studying and promoting a hierarchical paradigm for programming

non-embarrassingly parallel scientific computing applications on distributed,

heterogeneous, computing platforms. The target applications require the

numerical resolution of systems of partial differential PDEs modeling

electromagnetic wave propagation (CEM) and fluid flow (CFD) problems. More

importantly, the underlying numerical methods share the use of unstructured

meshes and are based on well known finite element and finite volume

formulations.

The general objective of this postdoctoral project will be to design and

experiment mesh partitioning strategies that take into account: (a) the

heterogeneity of processing nodes and interconnection networks of a grid

computing platform and, (b) the hierarchical parallel programming paradigm

considered in the DiscoGrid project. The proposed work will also include the

adaptation of existing parallel simulation software in order to deal with the

hierarchical programming model.

**Subject: PhD Studentship in Parallel Mesh Generation at U British Columbia**

PhD Studentship in Parallel Mesh Generation at U British Columbia

The Advanced Numerical Simulation Laboratory at the University of

British Columbia develops unstructured mesh generation algorithms and

numerical methods for accurate, efficient solution of PDE's on

unstructured meshes (with an emphasis on problems in aerodynamics).

We currently have a need to extend our mesh generation code to run in

massively parallel environments (thousands of processors), to provide

meshing and adaptation support for applications both within and outside

our group. We will almost certainly need to go beyond existing research

in parallel unstructured meshing to develop algorithms that scale

sufficiently well.

This position is a PhD research studentship, with an anticipated start

date of January 2007. The successful applicant should have a background

in CFD and strong C++ programming skills. Experience with unstructured

mesh generation will be helpful but it is not essential. Students whose

background is in a field other than mechanical engineering can easily be

accomodated through UBC's interdisciplinary Institute for Applied

Mathematics.
