Overview
********

The workshop will review recent developments in programming models for
parallel applications, outline the features of some of the RAPS parallel
benchmarks and present some complementary international initiatives.
The current status of the proposed European Union Framework 4 Program
will be presented.
One session of the workshop will give vendors an opportunity to show
the results of RAPS benchmarks on their latest machines. In the final
session results obtained by the developers of the codes will be presented.

The RAPS Consortium
*******************

The RAPS (Real Applications on Parallel Systems) consortium came
into existence to promote the creation of benchmarks for important
applications on massively-parallel computers. As part of this activity
it has a strong interest in adopting a programming model that can
provide portability without  excessive sacrifice of performance.
The current adopted programming model is PARMACS, which is available on
all the participating  vendors' parallel supercomputers. The
consortium consists of a number of users and developers of significant
large production codes running on supercomputers. It is supported
by a Consultative Forum of computer manufacturers which currently includes
ACRI, Convex, Cray, Fujitsu, IBM, Intel, NEC and Thinking Machines Corp..

Hamburg:
********

The Free and Hanseatic City of Hamburg is the major harbor city
in the northern part of Germany. About 2 million people are
living in Hamburg and its surroundings. It is also the location
of many other scientific research labs.
The Deutsche Klimarechenzentrum (DKRZ), located in the heart of
Hamburg, is one of the major scientific computing centres of the
world dedicated to climate research. In May the climate in Hamburg
is very mild, so the social event will take place on a boat.
