WEDNESDAY 8:30 A.M. - 9:30 A.M.
The history of high performance computing and communications has been filled with crises, innovations, and opportunities. A glimpse into the past reveals numerous critical periods that shaped where we are today, as well as the evolving role of Federal activities. Will the future be different?
In the early 1990s, for example, the Government faced a crisis in providing the high performance computing and communications required to better address Federal science and engineering agency mission needs. The Government responded with the Federal High Performance Computing and Communications Program and the passage of the High Performance Computing Act of 1991. Since then the Program's investments have led to innovative new technologies, including scalable parallel processing systems, high performance networking technologies, World Wide Web browsers, and a broad range of applications that use these technologies, such as weather forecasting, environmental modeling, and biomedical imaging. These technologies have become necessary tools of Government and business, and public acceptance of new networking technologies has been astonishingly rapid.
Once again the Federal government faces a critical need for even more advanced computing, information and communications technologies. The HPCC Program is evolving into a focused collection of new CIC R&D; programs to develop technologies needed throughout the Federal government and to maintain U.S. technological leadership and competitiveness in the global marketplace. Government-coordinated technology R&D;, in partnership with universities and major high-technology corporations, can create fresh opportunities that lead the way to advancing the frontiers of Computing, Information, and Communications.
With the rapid pace of innovation and the accelerated needs of the Federal sector, a long term strategy deeply rooted in the fundamentals of computing, information and communications will be described, along with important lessons we can take from our proud history of success.
THURSDAY 8:30 A.M. - 9:30 A.M.
Numerical weather prediction is an initial value, boundary condition problem in which behavior of the atmosphere is to be predicted up to two weeks ahead. In this timeframe, the future state of the atmosphere at any point can be influenced by events at very distant geographical locations. This and other scientific and technical issues dictate that the numerical models employed to carry out predictions beyond a few days, medium-range forecasts, must be global in extent and must describe the atmosphere from the earth's surface to a height of 30 km.
A description of the three main components of the ECMWF global prediction system will be given:
The computational cost of each component is dominated by the cost of integrating global models with a wide range of resolutions. A description will be offered of the approach taken to develop a portable parallel model which has achieved high efficiencies on a wide variety of machines, including the Fujitsu VPP700 that was installed at ECMWF in July 1996.
(This talk will occur after the awards presentation. See page 16 for details.)
Alvy Ray Smith has been a leader in computer graphics for over 20 years. Within the entertainment business, he directed the first use of full computer graphics in a successful major motion picture, "Star Trek II: The Wrath of Khan," the "Genesis Demo," while at Lucasfilm. He hired John Lasseter, Disney-trained animator, and directed him in his first film, "The Adventures of Andre & Wally B." The team he formed for these pieces proceeded, under Lasseter as artistic director at Pixar, to create "Tin Toy," the first computer animation ever to win an Academy Award, and the first completely computer-generated film, "Toy Story," Disney's Christmas '95 release. Smith will discuss some of his concepts and successes and will treat the audience by showing bits of "Toy Story."

Computing "Grand Challenge" in Airplane Design
We used to formulate "grand challenge" problems in computing: those we were ready to solve if only we had enough computing power. Airplane design was thought to be one of those problems. Experience from the 777 design shows the problem to be much tougher than this. Changing customer needs causes some rethinking in the overall objectives. Formulating mathematical models, getting data and using good judgment are partners with solving a formulated problem using powerful computers. In this presentation we will illustrate these issues and identify some challenges for the future.

Deep Blue: The IBM Chess Machine
Deep Blue, the new IBM Chess Machine, recently made history by becoming the first computer to beat the human World Chess Champion, Garry Kasparov, in a regulation game. Although Kasparov came back to win the 6-game match, Deep Blue demonstrated that the approach of combining special-purpose hardware together with the IBM SP2 parallel processor can achieve previously unreachable levels of performance. In this talk we will describe the background of the Deep Blue machine, show video highlights of the match and discuss implications of the event on chess and technology.

Information Technology and Healthcare
There have been a number of remarkable recent achievements in biomedical research and patient health care delivery. These include the development of excellent clinical applications, as well as infrastructural information resources such as the Visible Human, Unified Medical Language System, HL7 and DICOM imaging data standards, Internet Grateful Med, Entrez and biotechnology inquiry tools. In all these applications, biomedicine has been a happy and grateful beneficiary of Internet and World Wide Web technology that was created for wholly different purposes. But these applications and tools alone are not enough.
It is unfortunate that most medical groups are still happily lodged in an old-fashioned Medicine Wagon, content to remain parked on the edge of the Electronic Highway. To sustain advanced achievements in medical science, and to develop even more powerful clinical interventions, we are greatly in need of improved information systems. We need wise investments in medical informatics to speed further scientific discovery, to help assure both quality and efficiency in patient care, and to encourage lifelong learning both by the medical profession and the public. Currently, telemedicine is the strategy holding the greatest potential for rapid advances in these areas.

Supercomputing in the Clinic
Soon after discovering the x-ray, scientists noted that some cancerous tumors regressed after exposure to radiation. Permanent tumor control could only be achieved with very high radiation doses that damaged surrounding normal tissue. To minimize this, early clinicians experimented with multiple radiation beams that overlapped only over the tumor volume. By the 1930s, this complexity made pre-treatment planning a necessity. Since radiation portal design using external patient anatomic landmarks to locate the tumor had to be done manually, clinicians could consider only a limited number of alternatives. By the 1960s the increased speed of computerized dosimetry enabled the generation of multiple plans.
Computed tomography (CT) scanning has recently been used to build 3D patient models, enabling substantial and realistic "pre-treatment experimentation" with multiple candidate plans and more accurate tumor targeting. The current challenge is to understand and improve underlying patient/tumor models. This requires image segmentation-dividing the data into logical and sensible parts-which is today performed by humans; computational solutions are needed. Additionally, a real understanding of complex 3D images requires high, preferably real time interactivity in order to rapidly manipulate the way data are displayed. These tasks are a challenge for today's fastest commercial workstation and should be considered supercomputing problems.
"Downloading" magnetic resonance scanning, nuclear medicine studies, 3D ultrasound, antibody scans, and nuclear magnetic resonance spectroscopy data onto the planning CT can produce a 3D model of the patient that shows the most information-rich features of all these diagnostics. Automating the spatial registration of the CT with the other 3D studies is an additional supercomputing problem.

Director for Virtual Environments, NCSA The I-WAY: Lessons Learned and Bridges BurnedThe I-WAY experiment at SC'95 was a transient phenomenon designed to find the flaws in the concept of a nationwide ATM network for research. The I-WAY team found them. We have since been working on the "Persistent I-WAY" with plans for solutions to those problems that aren't going away by themselves. This talk will present the case from the applications point of view with attention to middleware and networking issues.

Developing the Second Generation Internet
This abstract was written at the end of July . At that time many strands of the high performance networking were changing on a weekly basis and it was impossible to predict which would be the most interesting subjects four months hence. Some of these strands included: networking support for the partnerships for advanced computational infrastructure (PACI); development of high performance networking for the research and education community; interconnection of high performance federal research networks; interconnections of global research networks; and expanded public-private partnerships to accelerate the development of high performance networks. The strands that have major developments before November will likely be of interest to SC'96 attendees and will be reported in this talk.

TUESDAY 1:30 P.M. - 3:00 P.M. Supercomputing Applications in Medicine Moderator: John Gilbertson, The University of PittsburghComputing systems have become central to medical care and research, and their success has created a demand for systems with ever increasing capabilities. Some applications are reaching computing power, bandwidth and storage requirements associated with supercomputers. The multimedia electronic patient record is such an application, especially at major medical centers where large scale image storage is becoming common. At the University of Pittsburgh Medical Center, a supercomputer-like machine (MARS - Medical Archival System) is now used for this purpose. In addition, current high-end workstations based on the Alpha and other leading-edge microprocessors now have the compute power and memory bandwidth of supercomputers 10 years ago. Assuming this trend continues, we should ask what medical applications the supercomputer community should be developing today that may run on desktop machines in the next decade.
TUESDAY 3:30 P.M. - 5:00 P.M. Ten Years of K-12 High Performance Computing and Communications: What have we learned? What are we building for the future?

A lengthy question and answer session will follow the discussions.
THURSDAY 10:00 A.M. - 12:00 P.M. Opportunities and Barriers to Petaflops Computing Moderator: Paul Messina, CalTechPetaflops computing has been explored through a series of federally sponsored community led forums. Although the feasibility and application of petaflops systems within the next twenty years are considered a distinct possibility, there are highly conflicting views concerning the means by which this is to be achieved. Such issues as architectural capabilities, system software user interface, exotic technologies, applications that will benefit, economic business model in support of industry, and research and development paths are all considered controversial. Also, diverse perspectives are sometimes in direct conflict. For example, one approach dictates the use of commercial off-the-shelf components as the only practical approach to funding the necessary hardware and software technology. Another approach considers alternative structures of processing logic and memory on a single chip for more efficient computing. A third approach proposes to exploit exotic technologies in hybrid organizations, including superconducting logic, optical communications and storage, and semiconductor memories. At the same time, it is quite possible that the first petaflops computer will be a special-purpose device good for only a single class of applications but available in just a few years. Other approaches have been considered as well.
The panel will present an array of such views and invite the audience to contribute their own ideas on possible paths to petaflops computing.
THURSDAY 3:30 P.M. - 5:00 P.M. Scalable I/O Initiative Roundtable on Portable Programming Interfaces for Parallel Filesystems Moderator: Jim Zelenka, Carnegie Mellon UniversityThe Scalable I/O (SIO) Initiative intends to release for public review a draft parallel filesystem API suite no later than six weeks before this conference. The goal of this suite is to define a common set of powerful interfaces for application, compiler and toolkit programmers to use for high-performance I/O on a variety of parallel machine architectures. In this roundtable, the SIO Initiative would like to collect, interpret and discuss the community's responses to, and suggestions for, the proposed API suite. Broad-based comments are sought, but we will be especially interested in the programming experiences of I/O-intensive applications, out-of-core compilers/toolkits and parallel file system implementations. This draft will be available no later than October 1, 1996 at: http://www.cs.cmu.edu/Web/Groups/PDL/SIO/SC96.html.
