DOE Workshop on
Ultra High-Speed Transport Protocols and Network Provisioning
for Large-Science Applications
April 10-11, 2003
Argonne National Laboratory
Argonne, IL
Sponsor: Office of Science, U. S. Department of Energy
A
preliminary draft of the workshop report is currently available.
Workshop Goal and Objectives
Objective of this workshop is to address the research, design,
development, testing and deployment aspects of network provisioning and
transport protocols as well as application-level capability needed to
build in time the operational ultra-speed networks to support emerging
DOE distributed large-scale science applications. Our task comprises of
identifying the radical new and relevant existing technologies that can
meet the unique projected networking requirements of DOE's science
mission. The workshop goals include Identify the grand R&D
challenges that must be overcome in order to develop, test, and deploy
advanced networking technologies that timely satisfy the unique DOE
networking requirements within the next decade.
Identify and assess radical yet scalable dynamic provisioning
techniques and the corresponding technologies needed to effectively and
efficiently manage the high-capacity core networks with the required
extraordinary capabilities
Develop the framework for advanced transport protocols with
extraordinary capabilities to deliver multi-gigabits throughput in the
next few years and terabits/sec towards the end of the next decade.
Workshop Format
This is a "working" workshop in which participants will focus
on specific network issues identified for DOE large-science
applications. The participants will be provided with documents
summarizing the network requirements of DOE large-science applications
prior to the workshop. This advanced knowledge of the "unique" network
requirements of DOE's science applications will help the participants to
identify research, development, and deployment issues of ultra
high-speed networks. The workshop participants will be organized into
three groups corresponding to the main objectives of the workshop
outlined above. The output of the workshop is a report of the
discussions, findings, and research and development directions of the
groups.
The Need and the Potential
DOE's large-scale science computations and experiments are
critical to accelerate the scientific discovery in fields as diverse as
earth science, high energy and nuclear physics, astrophysics, fusion
energy science, molecular dynamics, nanoscience, and genomics. Several
of these computations are expected to operate at 100 teraflops levels
and generate hundreds of petabytes of data. DOE's complex science
instruments and large-scale simulation are anticipated to generate
terabytes of data that will be required to be transmitted to scientific
facilities worldwide for analysis and visualization. Ultra high-speed
networks hold an enormous potential for expanding the scope and impact
of these large-scientific endeavors with national and international
impacts Unprecedented access to the geographically dispersed resources
such as distributed terascale computing facilities, Petabyte data
archives, high-performance visualization centers, and remote steering
of complex science instruments, call for networking infrastructure with
unprecedented capabilities. In a nutshell, these network capabilities
can add a whole new dimension to the accessibility of DOE supercomputers
and experimental facilities, and eliminate the "single location
bottlenecks" that currently plague these valuable resources. The
network capabilities required in these large-science projects far
exceed the functionality of today's leading-edge high-speed network
technologies. Several large-scale science applications demand networks
to deliver hundreds of Gbits/sec as controlled/stable streams to the
users in near future and terabits/sec within the next decade. To meet
such demands, the networks have to be suitably provisioned for
high-speed operations. Furthermore the bandwidths available at the
backbone must be efficiently harnessed at the application level through
new advances in host systems as well as network components such as
transport protocols and network optimized I/O systems. The focus of this
workshop is the ultra high-speed transport protocols and dynamic
provisioning to support the large-scale science applications.
