Subject: Question about softare perturbation analyses
Prof. Bill Kahan in section 14 of his paper "mindless", describes a way to
bracket code fragments that are hyper-sensitive to round-off errors. To my
understanding, the method is a sensitivity analysis done by applying small
(functional) perturbations to the computation, instead of the data, details:
http://www.eecs.berkeley.edu/~wkahan/Mindless.pdf
I would be interested to know of numerical applications or techniques where
perturbations are applied to the computation or to the data to locate
algorithmic or software issues that cannot be located by looking at a
continuous gradient. This is an open ended question.

Sparse Days at CERFACS
Registration deadline: 23 May, 2008.
Web site: http://www.cerfacs.fr/algor/
As announced earlier, the "Sparse days at CERFACS" will be held at
CERFACS this year on 23rd and 24th June 2008. The meeting will start
mid-morning on Monday June 23rd and finish late-afternoon on the 24th
although the exact schedule will depend on the papers accepted for
presentation. The meeting will be a Workshop of the VECPAR 2008
meeting that will be held in Toulouse from 24-27 June. The main theme
of the Sparse Days this year will reflect this and be on vector and
parallel computing, including also work on modern architectures like
multicores, graphics processing units etc., although any contribution
involving sparse matrix research or applications is welcome.
As usual there will be no registration fee, although you must register
beforehand with Nicole Boutet (boutet@cerfacs.fr). People who have
already registered for the workshop through the VECPAR web pages need
not re-register. You should also let Nicole know if you want to stay
in the very cheap (but very adequate) on-site accommodation. There
will be a conference dinner on Tuesday evening, the cost of which will
be 40 euros.
People wanting to speak should email Xavier Vasseur
(vasseur@cerfacs.fr) with a title and abstract (one page in plain text
or LaTeX). We do not want to have parallel sessions so we will not
necessarily be able to accept all submissions. You should indicate
the time, t, that you would ideally like for your presentation, 15 min
<= t <= 45 min and we will try to accommodate this request within the
constraint of having no parallel sessions and finishing by around
17.00 on June 24th. A poster session will be available. Please let us
know if you would prefer this mode of presentation.
In memory of Gene Golub who attended many previous Sparse Days, the
meeting and dinner will have dedications to him and any speaker who
knew Gene is welcome to include remarks in his or her presentation.
The deadline for submitting abstracts (one page in plain text or
LaTeX), for registering, and for requesting cheap accommodation is May
23rd.

Gould). With 15-20 PhD students and many visitors,
this is one of the leading numerical analysis research
groups in the UK and, indeed, in the world.
In the standard Oxford manner, the appointee will also
hold a tutorial fellowship at a college, with
responsibilities for teaching undergraduates. The title
will be University Lecturer by default, or possibly
Reader or Professor for appointees at a sufficiently
senior level. The college is Exeter, right in the heart
of medieval Oxford, founded in 1314 (Tolkien was an
undergraduate and Inspector Morse died in the Front Quad).

aiming at distinctive MSc results with migration to PhD studies in
applied mathematics are invited to apply. Fundings are not available
for students at the MSc level. However students successfully completed
the MSc with distinctive results will be selected to continue a PhD
research programme, which will then be fully funded, at the
Centre for Numerical Modelling and Process Analysis. Please refer to

Deadline for application: 30/06/2008 for September 2008 entrance.
Deadline for application: 09/11/2008 for January 2009 entrance.
Application form from http://ammsc.gre.ac.uk
The Masters programme is run by the Department of Mathematical
Sciences at Greenwich, within the School of of Computing and Mathematical
Sciences. This highly regarded department was ranked 10th in the 2007
UK departmental ranking
(http://www.timesonline.co.uk/section/0,,6734,00.html),
and the MSc is taught by members of the Centre for Numerical Modelling
and Process Analysis, an award winning research group.
This Masters programme aims to train and equip Honours graduates in
engineering, science or mathematics and suitably qualified professionals,
with the skills required to understand, and use, applied mathematical
modelling techniques and scientific computing technologies in industry.
Emphasis will be placed on modelling phenomena governed by the physics of
fluid flow, heat transfer, electromagnetics and solid mechanics using CFD,
FEA and other software tools. A core philosophy of the programme is to
introduce the students to the concept of multi-physics modelling, where
interactions between the governing physics, and hence the relevant solution
and software technologies, are important. A strand of the programme is
devoted to Fire and Evacuation modelling, for candidates with Fire Safety
degree background. Details of available modules can be found at:
http://ammsc.gre.ac.uk
Entry requirements: A good Bachelor's degree in engineering, physics,
mathematics or a relevant related discipline. Those who have
substantial commercial or industrial experience but lack formal
qualifications should seek an interview with the programme leader.
