DEISA, ein Verbund von großen Supercomputerzentren in Europa, darunter auch das
Leibniz-Rechenzentrum der Bayerischen Akademie der Wissenschaften, und das
amerikanische Pendant TeraGrid wurden am 15. November 2005 auf der
Supercomputing-Konferenz SC05 in Seattle durch ein transkontinentales,
gemeinsames Filesystem verbunden, das den schnellen und umfassenden Zugriff auf
Daten und Anwendungen im gemeinsamen Computernetzwerk (Grid) ermöglicht.

American and European supercomputing infrastructures linked through a common
wide-area global file system
Seattle, Nov 15, 2005. TeraGrid (www.teragrid.org), the US supercomputing
cyberinfrastructure, and DEISA (www.deisa.org), the corresponding European
supercomputing grid infrastructure, have been linked, for the purposes of a
technology demonstration, by a common, scalable, wide-area global file system
spanning two continents.
The bridging of communities in the old and the new world were showcased during
the Supercomputing Conference SC05 at Seattle. It was shown that any scientist,
accessing TeraGrid from any of the participating sites in the US, or accessing
DEISA from any of the DEISA sites in France, Germany or Italy, can directly and
transparently create or access collaborative data stored in the now linked
grid-wide global file systems of TeraGrid and DEISA with one common file address
space. The even more important aspect is that the same is true for applications
which, executed at any of the participating sites, transparently access data in
the common file address space.
High performance wide-area global file systems as GPFS from IBM open totally new
modes of operation within grid infrastructures, especially in supercomputing
grids with a fairly limited number of participating sites. A common data
repository with fast access, transparently accessible both by applications
running anywhere in the grid, and by scientists working at any partner site as
entry point to the grid, greatly facilitates cooperative scientific work at the
continually increasing geographically distributed scientific communities.
Both DEISA and TeraGrid have begun using the high performance wide-area global
file system GPFS from IBM in production mode. For the technology demonstration,
the dedicated DEISA and TeraGrid networks were interconnected with the help of
specialists from GEANT, Abilene/Internet2, and the national research networks
from France, Germany, and Italy (RENATER, DFN, GARR). They established a two
continent spanning high performance network between TeraGrid sites at The San
Diego Supercomputer Center (SDSC), Chicago, and Indiana, and DEISA sites in
several European countries (France, Germany, Italy). Over this dedicated
connection, DEISA and TeraGrid global file systems were merged into one common
global file system. This network connection between the two infrastructures is
expected to become persistent at some time in the future.
The demonstration featured the execution of supercomputing applications of
various scientific disciplines which were carried out both as TeraGrid and as
DEISA applications. Single site applications transparently wrote their results
to the intercontinental global file system, ready for transparent further
processing from other access grid access points.
Featured applications for the demo included a Protein Structure Prediction and a
Cosmological Simulation carried out at SDSC, US (www.sdsc.edu) and a Gyrokinetic
Turbulence Simulation and also a Cosmological Simulation carried out at Garching
Computing Centre of the Max Planck Society (RZG), Germany (www.rzg.mpg.de).
TerGrid:
Sponsored by the National Science Foundation (NSF), the TeraGrid is a
partnership of researchers, computational experts, and resource providers that
together provide a comprehen-sive cyberinfrastructure to enable discovery in
science and engineering. TeraGrid and its education and mentoring programs
connect and broaden scientific communities. NSF established the TeraGrid
resources and their integration as part of a Major Research Equipment
construction project from 2001 to 2004. In August 2005, NSF extended its support
for the TeraGrid a set of awards for operation, user support and enhancement of
the TeraGrid facility over the next five years. Eight resource provider partners
(Indiana University, National Center for Supercomputing Applications, Oak Ridge
National Laboratory, Pittsburgh Supercomputing Center, Purdue University, San
Diego Supercomputer Center, Texas Advanced Computing Center, and The University
of Chicago / Argonne National Laboratory) were funded along with an award to the
University of Chicago to coordinate and integrate TeraGrid via the Grid
Infrastructure Group (GIG).

DEISA:
DEISA, the Distributed European Infrastructure for Supercomputing Applications,
is an EU FP6 Research Infrastructure project. All major European supercomputing
centres are jointly deploying and operating a unified supercomputing
infrastructure on top of national services. The DEISA Consortium is constituted
from eleven partners (BSC, CINECA, CSC, ECMWF, EPCC, FZJ, HLRS, IDRIS, LRZ, RZG
and SARA) from seven European countries (Finland, France, Germany, Italy, The
Netherlands, Spain and UK). The DEISA project started in 2004 and entered
production mode in 2005.
