Subject: Cleve Moler Honored by U. of Waterloo

Congratulations to Cleve Moler, who this past weekend, received an honorary
Doctor of Mathematics degree from the University of Waterloo, in Ontario
Canada. Cleve was chosen because of his, "major influence on education and
research in numerical mathematics and scientific computing." He also gave a
convocation address to the mathematics graduates on Saturday, June 16, which

Subject: A Library of Sparse Linear Solvers

I am pleased to announce the availability of TAUCS, a library of sparse
linear solvers. The two noteworthy aspects of the library are fast direct
solvers for symmetric positive-definite systems (supernodal multifrontal
and supernodal left-looking, both using the dense BLAS), and an implemetation
of Vaidya's augmented maximum-weight-basis preconditioners, including
recursive (multilevel) ones. The library also includes iterative solvers,
drop-tolerance incomplete cholesky factorizations, and convenient
interfaces to ordering codes.

You can download a package containing the library, example programs,
and documentation from

The code is by me and by my students Doron Chen and Vladimir Rotkin.

Regards, Sivan Toledo

Subject: Cluster Workshop at SIAM Annual Meeting

Short Course:

Setting up and Using a Small Linux Cluster
July 8, 2001, Town and Country Resort Hotel, San Diego, California
Preceeding the SIAM Annual Meeting

David Moulton, Los Alamos National Laboratory

The primary objective of this workshop is to communicate the necessary
information about hardware, software and application considerations so
that participants can analyze their own needs and potential use of
clusters. To this end we will provide an overview of hardware related
issues, a comprehensive list of freely available software resources
(both administrative and developer related), and an overview of the
computational work performed on the Avalon cluster
( at the Los Alamos National Laboratory.
To help make this truly practical we will bring a small cluster and
demonstrate various stages of construction and configuration as well
as compiling and running a parallel code.

Level of Presentation:
30% Introductory, 40% Intermediate, 20% Advanced

Who Should Attend?
This short-course is intended for faculty, students, professional
scientists and engineers that are interested in parallel computing but
generally find the necessary resources are either too costly or simply
unavailable. Specifically, we'll demonstrate the potential of
low-cost and reliable small to medium size Linux clusters that are
suitable for research groups and departments.

Mathematical Modeling and Analysis Group

Patrick Goda
