running in Potsdam. Using only your browser, you can check all simulation parameters, change any that
are "steerable", visualize live results, and more. Check the HOWTO on how to add this functionality to your own Cactus Simulations. More details to be provided soon. [Note: Microsoft Internet Explorer not yet fully supported]

Cactus 4.0 beta 2.0 is released after First Cactus Workshop.
The first Cactus Workshop, held in Champaign-Urbana jointly by the
NCSA
and the AEI, was a great success.
There were 66 registered attendees
of which 25 were speakers, the workshop covering parallel computing, an
introduction to the Cactus Code, an overview of the software and hardware
technology that can be accessed through Cactus, and Numerical Relativity
with Cactus.
The workshop was
webcasted (RealVideo/Audio) by NCSA , and the
slides are
available from our web pages. We would like to thank everyone who came
along and helped make it such a fun and interesting week!

Cactus 4.0 beta is released. After some
delays (we promised this would be done in January
of 1998 ;-) the first release to
the general public is ready for beta testing.
The flesh is complete! Many thorns are available and
we hope that it even works most of the time ;-)
Follow the instructions in our
download section to get your own copy!
And please send us feedback
or bug reports.

NCSA and AEI Offer Intro to Parallel
Computing and Cactus Workshop : Two
consecutive workshops are planned for this fall
at NCSA, focusing on Parallel Computing and using
Cactus, a framework for solving partial differential
equations (PDEs) on parallel architectures and used
extensively for 3D numerical relativity and
astrophysics problems. Check the
Workshop
announcement for complete information and
registration.

Record breaking computations at
NCSA: Cactus was used in recordbreaking
calculations performed on a 256 processor Origin at
NCSA. Total
computation time exceeded 100,000 CPU hours in one
month. See the current issue of Datalink
and the Access
Newsletter for an amusing story explaining the
science behind this feat.

Cactus used in Supercomputing 98:
Using tightly coupled supercomputers
in Europe and America, an intercontinental,
distributed simulation of the full 3D Einstein
equations of general relativity was performed,
calculating the collision of black holes and
neutron stars. The simulation itself was
distributed across supercomputers on both
continents, utilizing Globus, and was
controlled and displayed live on a Immersadesk
Virtual Reality system at SC'98 in Orlando, FL.

Heinz-Billing-Preis 1998: The
Heinz-Billing-Preis-1998 was awarded to Edward
Seidel in recognition of his group's work in scientific
computing including the Cactus
Code. This award is given by the
Max-Billing-Society to promote scientific
computing within the Max-Planck Society.

Cactus scales on NCSA NT Supercluster
This week, the Cactus code scaled nearly linearly on the NCSA
Windows-NT based Supercluster. As shown in talks given by NCSA
director Larry Smarr at several institutes and conferences in Europe
this week, the code achieved speedups above 120 on 128 processors. The
scaling performance was very similar to the NCSA 128 processor Origin
2000 (although the Origin 2000 was about 2.5 times faster per
processor due to aggressive Cactus optimizations on the O2K).

Cactus used in a demo in
Supercomputing 97 as part of a four institution
collaboration between the MPI fuer
Gravitationsphysik, Rechenzentrum Garching der
MPG, National
Center for Supercomputing Applications, and Argonne National Lab.
The
SC97 project, which involves distributed
visualization and computing over the atlantic
ocean is a testbed of high speed networking, and
demonstrates visualization features added to the
code by RZG and NCSA researchers Manuel Panea,
Ulrich Schwenn, and John Shalf.
