Subject: Matrices with Orthonormal Columns

On the topic of naming matrices with orthonormal rows/and columns:

1) I strongly endorse the comments of Stewart and Swartztrauber that the
naming should use "row and column" rather than "left and right". The
left/right descriptions only become understandable in the context of
operations, whereas the row/column naming applies directly to the matrix in
question, in complete isolation from the usage.

2) The distinction between "orthonormal" and "orthogonal" bedevils the
graphics community. Whether we like it or not, the "common knowledge"
parsing of the "orthonormal" proceeds as follows:
a) The term "normal" is taken to imply correspondence to "surface normal",
which is (unfortunately) presumed to be a unit vector.
b) Since (by far) the most commonly occuring "matrix with unit vectors" in
graphics applications is a (3 by 3) pure rotation matrix, it is
(incorrectly) inferred that an "orthonormal" matrix
is a matrix representing pure rotation.

I'm not stating that line of "reasoning" as an endorsment; it's just
something that has to be expected when dealing with the (large and vibrant)
graphics community. Given the (unfortunate) multiple uses of "normal",
sometimes referiing to unit-ness of a single vector and sometimes to
perpendicular relationship of two vectors, ANY term which includes "normal"
will be widely misused. In this setting, it might be best to say "mutually
perpendicular rows (columns)" instead of "orthonormal".

Subject: Eigenvalues/Eigenvectors of a Implicitly Defined Matrix

I am interested in the efficient computation of the eigenvalues and
eigenvectors of an implicitely defined matrix F, which combines two
real rectangular data matrices (probably subjected to noise) X_1, X_0
of dimension m \times n, where n >> m, that is

X_1 = F X_0.

X_1 and X_0 can be partitioned into X_1 = [ A, a_n] X_0 = [ a_0, A ]

Hints and solutions are welcome.

Subject: SIAM at 50

As many of you will note, SIAM will be holding its 50th anniversary in
Philadelphia in July. It's would be great to celebrate this event; SIAM
has played such a great role in Applied Mathematics and Scientific
Computing.

It seems to me that the costs of this meeting is very high and it may
not be possible for many members to attend.
Here are the rates for the meeting hotel.
Single $167.0 Double$182.00
And there is on top of this a tax which is about 14%.
There is also a minimum registration fee of $250. I think SIAM needs to reassess the mode of operation for meetings. Perhaps it is appropriate to return to the old model of meeting at universities. Gene Golub PS I'm staying at the Loew's Philadelphia which has a more modest rate of$110 (plus taxes) per night.

SAC'03 is sponsored by the ACM Special Interest Group in Applied Computing (SIGAPP). The most recent previous ACM SAC conferences were held in Villa Olmo, Como, Italy (SAC'00); Las Vegas (SAC'01); and Madrid, Spain (SAC'02). Computational Science lies at the core of applied computing and is a traditional component of the SAC conference series. Authors are invited to contribute original papers to the Computational Sciences Track hosted by SAC '03. COMPUTATIONAL SCIENCES TRACK: The aims of this Track are to draw attention to new developments in computational sciences; to promote the exchange of ideas accross disciplinary boundaries; and to foster the education of young computational scientists. Major topics include, but are not limited to: * Numerical and Non-Numerical Algorithms of interest in applications; * Parallel and High-Performance Algorithms; * Computational Applications in all Scientific and Engineering fields (e.g. Biology, Chemistry, Mechanics, Statistics, Geosciences, etc); * New Computational Application Areas (e.g. Arts, Finance, etc.); * Optimization and Data Assimilation; * Problem-Solving Environments.

These software tools aim to simplify the solution of common and important computational problems and have substantially benefited a wide range of scientific and industrial applications. These benefits are accounted not only for running efficiently in high performing computing environments but also realizing computation that would not have been possible otherwise. Despite these successes, there is still a need for a greater infrastructure to reach out academia and industry through a dissemination and instruction on the state-of-the-art tools for high performance computing environments and simultaneously provide an umbrella for tool developers to receive the feedback from these communities. This workshop is part of an approach to build such an infrastructure. The three and half-day workshop will present an introduction to the ACTS Collection for application scientists whose research demand includes either large amounts of computation, a large volume of data manipulation, the use of robust numerical algorithms, or combinations of these. The workshop will include a range of tutorials on the tools (currently available in the collection and some deliverables from the DOE SciDAC ISICs), discussion sessions aimed to solve specific computational needs by the participants, and hands-on practices using the NERSC's state-of-the-art computers. We are planning to organize parallel sessions and group the tutorials by topics, as follows: Direct and Iterative Methods for the solution of linear and non-linear systems of equations PDE's and Multi-level Methods Numerical Optimization Structured and Unstructured meshes (Generation, Manipulation and Computation) Development of High Performance Computing applications Performance monitoring and tuning Grid computing DOE will fully sponsor a limited number of graduate students and postdoctoral fellows to participate in this event. This support includes round-trip transportation to and from Berkeley, local transportation, lodging, meals and workshop materials. Proposals from other research scientists are also encouraged. The deadline for applications is July 9, 2002, and they should be submitted using the application on-line form. Students and postdoctoral fellows should submit an abstract describing the nature of their work, future plans and/or current needs for computation. A letter of recommendation from the applicant's supervisor also needs to be provided using the recommendation on-line form. The recommendation letter must also arrive no later than July 9, 2002. Other applicants must submit a letter outlining their current work and future plans and needs for computational resources with a list of publications . For more information on the workshop, please contact Tony Drummond at (510) 486-7624 or Osni Marques at (510) 486-5290.
