Supercomputing conference pushes the boundaries of global connectivity
In keeping with the theme "Beyond Boundaries," Super Computing
2001 opened new horizons in global connectivity from the mile-high city,
Denver, Colo.
Participation by sites in 10 countries around the world, "from Bologna
to Beijing and Anchorage to Antarctica," in the annual conference
was made possible by the creation of one of the largest heterogeneous
computing networks in the world — a network constructed for just
one week. The conference brings together 5,000 leaders of the supercomputing
and network community from industry, academia and the national labs to
demonstrate new technologies and showcase results.
"The access grid, set up for SC Global as part of SC2001, made it
possible for people in different locations to be content providers to
the conference for the first time," said Dona Crawford, AD for Computation
and SC2001 exhibits chair. "This was a new feature that opened the
way for greater global participation. The talk of the conference seemed
to be ‘the grid’ (Data Grid, TeraGrid, Access Grid, Knowledge
Grid). The grid is the next step up from the Web."
A highlight of SC2001 was the announcement of the new supercomputing Top500
list. The Accelerated Strategic Computing Initiative’s "ASCI
White" retained the top place on the list with LLNL’s ASCI Blue
holding the number five ranking. Livermore has three other machines in
the top 100. Five of the top 10 machines are managed for Department of
Energy by the University of California.
"ASCI White is a very large team effort," said Dave Nowak, LLNL
ASCI program leader, at the Top500 ceremony. "This is the first truly
tri-lab machine benefiting Livermore, Los Alamos and Sandia national labs."
"When you’re number one, everybody looks at you closely,"
Crawford said, noting that there is a great deal of interest in high-end
computing in the pharmaceutical, automobile and aircraft industries.
Crawford said the Lab’s relationship with industry is a partnership
and that because high-performance computing is a limited commercial market,
the labs play an important role in developing new applications. "In
this symbiotic relationship, we act as early first users for these new
developments," she said. "The goal of ASCI is not only stockpile
stewardship, but to further the U.S. computer market."
While there are ongoing collaborations and dialogue between industry,
academia and the labs, SC2001 is the opportunity for participants to "show
their stuff" as well as exchange ideas. The conference includes an
extensive technical program including tutorials, workshops, panel discussions
and paper and poster presentations.
"This is also an opportunity for sponsors to come and assess the
progress of the programs they are funding," Crawford said. "In
a sense, it serves as a program review."
Global Grid Showcase
Much of the attention from media focused on the SC2001 Global Showcase,
demonstrating potential applications for the high-power — 15 gigabits
of bandwidth — network.
Bill Lennon, Lab engineer, organized a 45-minute presentation and multi-site
interactive demonstration using the SC Global Grid Showcase on the Visible
Embryo Project. The project is building a 10+ PetaByte Digital Library
to support teaching, research and clinical planning in embryology.
Participants from all over the world could "look over the shoulders"
of Visible Embryo Team members as they collaborated to describe the project
from four Access Grid Sites near their home institutions. The Access Grid
sites were in Arlington Va., Argonne, Ill., Denver and Livermore. Audio/video
feeds were multicast from each site in addition to a synchronized PowerPoint
presentation and a multicast image of the application window being demonstrated.
"This is a powerful new medium for collaborative scientific research,"
Lennon said.
Jeff Olsen of LLNL’s Electronics Engineering (EE) set up and ran
the temporary advanced communications and networking installation in Bldg.
132. George Pavel, also of EE, negotiated the Laboratory’s participation
with the other three access grid sites. Brian Bodtker and Paul Atwal of
EE assisted Olsen and were trained as backup "directors." Mark
Strauch participated as an LLNL virtual seminar attendee.
The project basis is the Carnegie Collection of Human Embryology located
at the Human Development Anatomy Center of the National Museum of Health
and Medicine within the Armed Forces Institute of Pathology. Team members
with complementary expertise are located at eight institutions throughout
the country, which are linked by "Next -Generation Internet"
research networks.
The Laboratory had lead responsibility under Jean Shuler for the tri-lab
ASCI booth in the Denver Convention Center this year. The booth featured
a power wall used for presentations by Livermore, Sandia and Los Alamos
researchers. Mark Seager, Steve Langer, Jack Reaugh and Valerio Pascucci
were among the LLNL researchers who made presentations at the ASCI display
wall.
Many other Laboratory employees, too numerous to mention, participated
in SC2001, presenting peer reviewed papers, tutorials, research posters
and coordinating or joining the Birds of a Feather sessions. The full
conference program can be found at

SC2002
will be held next November in Baltimore under the theme "Terabytes
to Insights." Details available at
