Subject: Virtual Cooperative Learning, Request for Partners

Request for Partners in Virtual Cooperative Learning for LP

The central ingredient of cooperative learning (CL) is that students
work together on problems. I have organized "virtual" CL (VCL) to
have students at different places work together on a common set of
problems. I am now eliciting VCL partners for a linear programming
(LP) course that I am teaching this Fall. If you are teaching LP at
the senior undergraduate/graduate level, please continue.

I did this for nonlinear programming with Leon Lasdon and Soren
Nielsen, and you can see our description at

(sorry for the long url). I taught Optimization Modeling that
semester, so the problems were about formulation, rather than about
the algorithms that solve them. Thus, we might teach different
kinds of LP courses, yet we could agree to a set of problems that
we want our students to solve.

My previous Network Flows class (S99) used VCL with Paul Jensen who
added a series of "short answer questions," which proved to be
extremely valuable. You can see these (and related things) at

While I am open to new ideas for its conduct, what I have in mind is
having groups of our students work cooperatively on a set of problems.
The idea is to have the problems near the beginning of the semester
and have students use the internet to communicate. Hypernews is
particularly suitable for transmitting mathematical notation, using
latex or HTex, and I can setup our page as in the two previous cases.

What we need is a problem set and a due date. I am thinking that
some date in late October or early November the students would
turn in their problems. We can decide whether we shall grade them
or have other students review them. In the latter case, we might
want to grade the reviews. In any case, it is not necessary for
us to grade the same way, but it is necessary for us to agree on
the what and when in order for the VCL to succeed (i.e., the
students learn more effectively).

There is no limit to the number of participating groups of
students, but I require each participating teacher to contribute
to the problem set that we shall derive. The goal is to have this
before August 21, which is when my class starts, but we could extend
it to September 1, if necessary. If I get any partners, I can
distribute a first draft early August, so we should have a couple
of weeks to iterate.

Please contact me via e-mail if you are interested in participating.

Subject: Report on the PARA2000 Workshop

Report on the PARA2000 Workshop

The PARA2000 Workshop on Applied Parallel Computing was held in Bergen,
Norway June 18-21, 2000. The Workshop was well organized by Professors
Petter Bjorstad and Tor Sorevik and their team. There were 9 invited
speakers and 40 contributed talks. The Workshop attracted about 70
participants from several countries. The papers presented will be
published by Springer Verlag in their "Lecture Notes in Computer Science"

The Workshop was preceded by a tutorial on "OpenMP" (June 18). Two social
events were organized. 1) A reception, hosted by the mayor of Bergen, at
the Old City Museum (June 19). Before turning to politics, the mayor had
been a computer scientist at the Bergen University Computing Center. 2)
The Conference Dinner, which was held at a beautiful mountain-top
restaurant (June 20).

During the dinner the PARA Steering Committee, consisting of Petter
Bjorstad (Norway), Bo Kagstrom (Sweden) and Jerzy Wasniewski (Denmark),
reported on the results of their earlier deliberations. The main points:
1) Thanks were due to Petter Bjorstad and his team for the excellent
PARA2000 organization. 2) Professor Jari Jarvinen from the Finnish Center
for Scientific Computing (Finland) was selected as an additional member of
the Committee. 3) Jari Jarvinen invited the PARA02 Workshop to be held in
Finland in June 2002. The precise dates and place will be announced soon.

Parallel CFD 2001, the thirteenth in an international series of meetings on
computational fluid dynamics for parallel computers, will be held from
May 21-23, 2001 in Egmond aan Zee, The Netherlands. The technical program
planned for the 3-day conference features nine invited speakers and three
tracks of contributed presentations.

The conference covers all relevant subjects with practical and industrial
issues as one of the traditional highlights. Keywords are: industrial
applications, turbulence, reactive flow, multiphase flow, multiphysics
flow, environmental flow, parallel multiblock/multigrid solvers for fluids
(domain decomposition, multigrid, Krylov methods, Newton/Krylov). In 2001
special attention will be paid to multidisciplinary questions exploring
parallel computers for its solutions and the usage of parallel flow solvers
as a building block therein (optimal design, parameter sensitivity, parameter
estimation, reliability analysis).
