Subject: Philip Rabinowitz (1926-2006)

I have just learned that Philip Rabinowitz passed away on July 21, 2006,
a few weeks before his 80th birthday.

Although this happened about a year ago, it appears that this was
not noticed by the numerical analysis community. Many know the book
"Methods of Numerical Integration" he wrote with Phil Davis.

Some biographical notes and anecdotes are given in the text
"Remembering Philip Rabinowitz" by P.J. Davis & A.S. Fraenkel,

Subject: Packages vs languages

Earlier this year there was an interesting discussion in NA Digest on the
relative merits of Matlab and Fortran for teaching Numerical Analysis. I
would be interested in contributions to a discussion of the following
related topic: the relative merits of commercial CFD/CHT packages (CFX,
FIDAP, Fluent, Phoenics, etc. etc.) and programming languages (APL, BASIC,
C++, Fortran, etc. etc.) for teaching computational fluid dynamics and
heat transfer.

On the one hand, packages are generally fairly easy to learn and students
can get to solving "real" problems quickly. On the other hand (and you may
detect my personal bias here!), do they really know what they are doing?
Given that commercial codes are not open, can they understand the models
and methods used? On the third hand, if a package will give them "the"
answer, do they need to understand models and methods?

In my view, if students do not have that understanding, they cannot
properly verify and validate the results they obtain.

Best wishes,
Graham de Vahl Davis.

Subject: CERFACS Sparse Days ... 20th Anniversary meeting, Oct 2007

Sparse Days at CERFACS ... CERFACS 20th Anniversary Meeting

As announced earlier, the Parallel Algorithms Team at CERFACS split its
annual "Sparse Days at CERFACS" this year between the Preconditioning 2007
meeting, which finished a couple of weeks ago, and the CERFACS Anniversary
meeting in October.

CERFACS will be celebrating its 20th Anniversary on October 10-12. There
will be general CERFACS activities on the afternoon and evening of
Thursday 11th with talks by Algo related people including Gene Golub,
Gerard Meurant, Philippe Toint and Alan Edelman.

The Parallel Algorithms Team will hold a Sparse Days meetings on
Wednesday 10th and the morning of Thursday 11th and a one-day meeting on
Friday 12th. Our plan for the Friday is that
Algo old boys (or girls) would give reflective talks ... partly
saying what they are doing now and relating it to the influence of
the Algo experience. This would not preclude the possibility of a straight
technical talk on the Friday although the conference room has been booked
on Wednesday and Thursday morning for this purpose.

We already have a draft programme for the Friday and a couple of talks for
Wednesday but there is still room for additions to either day.
In order that we can plan the meeting and book some place for the banquet,
we would like to get some ideas of the numbers both attending and speaking.
Although there is no official registration (and no registration fee!),
we would appreciate it if you could let us know by email whether you plan to
come by 7 September after which we will put the draft programme on the web.

So could you let us know by email whether you will come, whether you will
speak (and if so whether for Wed/Thurs or Friday ideally with a title for
your talk ... default of 30 minutes but let us know if you need more or less).

We do have some rooms booked in the meteo residences and are pleased to offer
free accommodation there on a first come first served basis.

We anticipate that the autumnal sparse days will be a fun event and look
forward to welcoming you to Toulouse in October.

We hope that you can come.

• Scattering Theory
• Porous Media

for more information. The Opening Workshop will be held on Sunday - Wednesday,
September 23 - 26, 2007 at the Radisson Hotel RTP in Research Triangle Park,
NC. Confirmed speakers and invited discussants include:

• Liliana Borcea (Rice)
• Weinan E (Princeton)
• Bjorn Engquist (UT Austin)
• Lisa Fauci (Tulane)
• Tom Hou (Cal Tech)
• Karl Kunisch (University of Graz)
• Randy LeVeque (Washington)

The list will be updated constantly.

Interested individuals are encouraged to apply to participate/speak in the
program, using the ON-LINE APPLICATION FORM. The on-line form also includes
the application for financial support. The deadline for the opening workshop
is August 16. You will be notified as soon as possible after your application
if your participation will be possible; regrettably, limited seating will
preclude acceptance of all applications. New researchers (graduate students,
postdocs, and faculty in the early stages of their careers) and members of
underrepresented groups are especially encouraged to apply. Please make
reservations at the Radisson as soon as possible. The SAMSI room block and
rate ($99) is effective until September 2, 2007. After this date, there is no
guarantee a room will be available.

More workshops/conferences will be announced later.
