Subject: References on Mesh Generation

I'm looking for general references on mesh generation as may be applied
to finite element methods. More specifically, if anyone is aware of
references discussing element metrics (quantitative measures of the quality
of a mesh), then this information would be greatly appreciated.

I'm aware of a text entitled "Automatic mesh generation: application to
finite element methods" by P.L. George, Wiley, 1991, but haven't been
able to track down a copy. Can anyone make a recommendation for this book?

Thanks in advance.

Bo Einarsson and Yurij Shokin have written a tutorial on the transition
from Fortran 77 to Fortran 90, with the title "Fortran 90 for the Fortran 77
programmer". The English version is available as a pure ASCII text file
via anonymous ftp from the computer nsc.liu.se (130.236.100.5) and is
available in the directory pub/bibliotek as the file f77to90.txt.

Subject: PICL 2.0 Now Available from Netlib

PICL 2.0, the latest version of the Portable Instrumented Communication
Library, is now available from netlib. PICL 2.0 represents a complete rewrite
of the library, and includes significant new functionality.

New documentation is in preparation. In the meantime, a summary of the new
features is provided in the file picl2.commands. The original reference manual
and user guide, a discussion of PICL programming models, and the report
describing the new trace file format are also provided with the distribution.

PLATFORMS:
In this initial release PICL 2.0 source is provided for:

1) NX/2
- mpsim hypercube simulator, Intel iPSC/2, iPSC/860, DELTA (hostless only),
Paragon/OSF, and Paragon/SUNMOS

2) VERTEX 3.0
- nCUBE/2 and nCUBE/2S

3) PVM 3.3
- sun and rs6000

A PVM/T3D port will be available in the near future, and other ports are in
progress.

FUTURE:
The development of proposed standards like MPI and the popularity of PVM
have decreased the need for low overhead compatibility libraries like PICL,
but standardization in instrumentation interface is less advanced, and may
never occur given the wide range of instrumentation requirements. PICL
instrumentation has proved very useful in our work, and we expect to continue
supporting and extending it by:

1) implementing PICL on top of MPI, retaining backward compatibility for
existing PICL programs, and

2) supporting PICL-style instrumentation logic and the PICL instrumentation
interface in MPI.

This is a high priority item, and we expect to have something available in
the near future.

PVM:
Using the PVM version of PICL on a network of workstations is useful in
developing parallel codes to be run on MPP platforms, but the PICL
message-passing interface and instrumentation logic were designed for
efficiency on tightly coupled homogeneous message-passing systems.
If the primary platform is the network, then the PVM instrumentation and
visualization tools are more appropriate (and powerful).

Note that commands setdata0 and getdata0 have been added to PICL to
support correct execution on heterogeneous networks. setdata0 is used to
inform PVM what datatype is being sent or received in subsequent send0 and
recv0 calls. The length arguments in send0 and recv0 are still byte counts,
and setdata0 is ignored in PVM on homogeneous networks and in the NX and
VERTEX implementations. getdata0 returns the currently defined datatype.

GETTING SOURCE:
The PICL source code and documentation are available from the Netlib
software repository. For instructions on how to obtain this material, send
the following message to netlib@ornl.gov:

send index from picl

You can also use the xnetlib interface to netlib or use Mosaic with the world
wide web address

Subject: High Performance Fortran Workshop

WORKSHOP ANNOUNCEMENT:

High Performance Fortran (HPF) - Four-Day Workshop
October 18 - 21, 1994
At the Swiss Scientific Computing Center, CSCS-ETHZ
Manno (Ticino), Switzerland

Applied Parallel Research (APR), in cooperation with the Swiss Scientific
Computing Center (CSCS-ETHZ), offers a four-day workshop on High Performance
Fortran (HPF). This will be an intensive training session with hands-on
experience using APR's HPF compilation system, xhpf. Attendees are encouraged
to prepare their own application codes for parallelization over a distributed
memory workstation cluster during the workshop.

This workshop will feature a programming tutorial on MPP systems and HPF, and
offer an opportunity to gain experience parallelizing real Fortran
applications using APR's newest parallelization tools. Ample time has been
allocated to allow each attendee, working at their own pace and with the
instructors and CSCS staff, to parallelize and evaluate real benchmark
programs and their own application codes. CSCS will provide access to MPP
systems on which to run parallelized codes.

The instructors will be John Levesque and Richard Friedman of Applied
Parallel Research. The workshop languages will be English and Fortran.

Spaces in this workshop are limited and will be available on a first come,
first served basis. It is recommended that you reserve a place by contacting
APR as soon as possible. The tuition fee for this four-day workshop will be
$1500 US. A reduced fee of $1250 applies to organizations with active FORGE
licenses. Full payment must be received at APR by September 16, 1994 to hold
a place.

the design concepts behind the code, the use of the library both through
the interactive drivers and calling programs, and the extension of the
library through the addition of new modules. The course will begin
at 9:00 AM on Monday morning and finish around 1:00 on Friday afternoon.

Course tuition is $300 for full-time academic participants and $600
for industrial participants. Purchase of the Modulef library involves
the payment of a one time Club Modulef entry fee and an annual license
fee. The entry fee is 2,000 FF for academic institutions and 8,000
FF for industrial corporations, and the license fee is 4,000 FF for
academic institutions and 12,000 FF for corporations. (The current
exchange rate is approximately 5.7 FF to the dollar.) The entry fee will
be waived for academic participants of the course who purchase the
code within six months of the course and reduced by 50% for industrial
participants.

Subject: Workshop on Solution Techniques for Large-Scale CFD

International Workshop on
Solution Techniques for Large-Scale
CFD Problems

September 26-28, 1994
Montreal, Quebec , Canada

Chairman : Prof. W.G. Habashi
Director-Industry, CERCA

THEME

An international Workshop on Solution Techniques for Large-Scale CFD Problems
seems topical and timely. The size and complexity of problems tackled today
demand the efforts of interdisciplinary teams from engineering, physics,
mathematics and computer science. These disciplines complement one another in
defining appropriate models that are amenable to discretization on today's
computers, algorithms that can be executed in reasonable turnaround times and
strategies that take advantage of state-of-the-art computer architectures. Only
when these elements are combined can one tackle the more challenging problems
of CFD in academia and industry.

The Workshop should be of considerable interest to engineers, scientists and
researchers using and/or developing CFD methods for scientific and industrial
applications. The Workshop is structured to promote interaction between
attendees and lecturers. Discussion periods will follow presentations.

POSTER SESSION

In addition to the invited lectures, a Poster Session will be organized.
Those wishing to participate should submit an abstract of up to 1,000 words
by July 15, 1994, to:

begin by asking who wishes to speak and setting the Circus schedule
accordingly. To provide a more informal atmosphere for discussion,
there will also be time set aside for Workshops on specific topics
of interest. The schedule for the Circus and Workshops will be
determined each day according to demand.

STUDENT PAPER COMPETITION

Travel and lodging assistance will be awarded to students judged to
have the best research papers. Papers with original research due
mainly to the student must be received before December 1, 1994. They
must be singly authored and no more than 10 pages in length. Sending
only an abstract is unacceptable. A panel of judges will determine
the best papers. Authors of the three best papers will be given a

to present their papers in a special session at the conference.
Several other students who participate in the competition may be
awarded free lodging and registration, depending on availability of
