Appendix A: Scientific and Technical
Goals and Objectives for Information and
Communications R & D

The Information and Communications (I&C) technology system is complex and dynamic. New technology flows from "developers" to "users" along increasing stages of maturity (i.e., from conceptual, early-stage science, to experimental mid-stage technology development, to mature, late-stage infrastructures in support of the next generation of science and technology). Technology also flows along increasingly complex and abstract levels of system structure (e.g., from primitive components assembled into communications systems, which are assembled into computing systems, and on through to applications).

Although it is easy to describe this flow of new technology as a linear process, reality is more complex. New knowledge and technologies develop in parallel and mix among the activities, ultimately progressing toward the goals set forth by the Strategic Focus Areas. Maturing technologies reach a stage where they no longer represent research in their own right. At this point they not only enter commercial development and broad scientific deployment, but they also play a critical role in enabling research and development. Examples include mature generations of scalable parallel multiprocessors supporting the Grand Challenges of science and engineering and moderate speed, and wide-area networks connecting "virtual" user communities to distributed resources. These become key elements of an underlying infrastructure for research and development.

Often the limitations of existing infrastructures encountered in their operational use (as they are scaled up or used in more diverse ways) motivates new conceptual breakthroughs. The development of the next generation of innovative technologies is fueled by providing developers with access to the latest infrastructures, thus providing a context in which to develop alternatives that address the fundamental limitations of existing systems.

As noted in Section 2.3, CIC has developed a taxonomy that characterizes the technology base underlying I&C research and development into seven broad areas. These areas represent the major building blocks of Agency-specific Federal Programs:

Components are the primitive physical building blocks of communications, computation, and information processing systems;

Communications addresses the technologies, services, and infrastructure of interconnected systems exchanging information in analog and digital forms;

Computing Systems focus on the structure, organization, and design of hardware and software for computational and information processing systems;

Support Software and Tools are the technologies for developing and managing the software creation, evolution, and maintenance processes, including applications building blocks and the operational software needed to provide system-level services to applications;

Intelligent Systems develop techniques for automated reasoning to advance the capabilities for aids to human-decision making and execution;

Information Management develops the capabilities for information retrieval, data management, and archival storage in support of applications;

Applications of specific interest to the CIC are those that use information technology in innovative ways, with intensive computation, information, communication, or distributed processing.

As part of the process to develop this strategic implementation plan, an informal budget crosscut was conducted to assess the overall distribution of CIC resources in the seven technology R&D activity areas, as well as the proportionate share currently invested in the Federal HPCC Program. These are reported in Figure 2 above. Information and Communications R & D funding is currently approximately $2 billion per year, of which half is for the HPCC Program. Since this represents the R&D investments, the government leverage of its investment to the entire worldwide industry is only 250:1.

It is important that these numbers should not be considered definitive crosscuts, and it is not CIC's intention to recommend crosscuts by the strategic focus areas at this time. Rather, CIC intends to use this important baseline, coupled to detailed implementation plans, such as the Federal HPCC Program and Agency submissions, to evolve a meaningful, streamlined approach based on the strategic focus areas to understand and manage important cooperative efforts in the future.

The following sections elaborate on the goals, opportunities, ongoing activities, new efforts and challenges for each of the seven I&C broad areas of research.


A.1. Components

Goals

The goal of the Components area is to develop component technologies over the next decade that will drive advances in computing and information technology. Component technology not only provides the information processing devices at the heart of computing and communication equipment, but also the interfaces with which information appliances interact with the physical world and with people. This effort will build on the National Electronics Manufacturing Initiative (NEMI) of the CIT committee.

Opportunities

Cheaper, smaller, and faster electronic components will improve today's applications and enable information technology to be applied to new domains, perform new services, and create new markets in the future. Revolutionary improvements in "bits per second per dollar" will be required to meet the demand of video-oriented customers for increasingly individualistic services that draw on global information. Visual communication requires improved displays and imagers. To balance increased processing and communication capability, mass data storage technology must continually improve, which demands the mastery of complex low-cost electromechanical systems. Improved radio frequency (RF) and infrared (IR) components are needed to support wireless connectivity, which implies that digital systems with lower power requirements must be developed, and that energy storage subsystems must improve. Interfacing these systems effectively with the physical world will require low cost sensors, sources, actuators, and displays, often customized to the application. Product development times and lifetimes continue to decrease as capital equipment costs explode. Modeling and simulation are critical to shortening the development cycle and preventing costly mistakes. Future opportunities lie in such areas as: optoelectronic components (with their enormous intrinsic bandwidths and low-loss fiber compatibility); the merging of microelectronics and micromechanics; and the newly emerging area of molecular electronics.

Ongoing Activities

Present R&D is focused on: processes for electronic components; optoelectronics; mass data storage; energy storage; electromechanical systems; modules and processes for interconnect systems; and electromechanical assembly, including packages, boards, and products. The driving force in semiconductor design and manufacturing is increasing miniaturization and function integration. In the area of optoelectronic displays, activities include: improved cathode ray tubes; flat panel and head-mounted displays using active matrix liquid crystals, electroluminescence, plasma, and cold cathode technologies; projection displays using digital micromirrors, liquid crystals, and laser projection.

New Efforts

New efforts are required in advancing display processing technology, such as high speed video processor modules, workstations, high bandwidth busses, image transmission over packet networks, and high bandwidth, digitally compressed video and data systems. New compression algorithms, graphics tools, graphics standards, and user interfaces also must be developed.

Infrastructure broadly applicable to component design and manufacturing is needed that will address such areas as: design tools; design for "X" (manufacturability, reliability, etc.); manufacturing automation; testbeds, including generic equipment and software; rapid prototyping and related services, including electronic and optoelectronic components.

Challenges

Longer term component research needs include: nanotechnology; complex physical device simulation; biology-based computing components (including sensors); fundamentals of electronic materials; optical components and systems; CAD synthesis algorithms to reduce time to market; models and characterization of devices, interconnects and packaging; methods for integrating processing into components such as sensors, displays, and mass storage devices; testbeds for evaluating or comparing component designs; test theory and algorithms; components for analog information processing. As components take on more function and become more complicated, techniques must be developed that can convert high-level descriptions of their requirements and specifications into efficient physical designs. Components using increasingly disparate technologies in complex combinations cannot be designed from theory alone. For device characterization, prototypes of these components must be built and measured to determine their behavioral characteristics in practice. As levels of integration increase, entire subsystems may be reduced to single components. Testbeds for comparing prototypes of such devices in realistic application environments will be needed.


A.2. Communications

Goals

The goal of the Communications area is to provide the necessary communications infrastructure and technologies to support the advanced requirements of the National and Grand Challenge class applications as well as to address the ubiquitous and universal accessibility required by the citizenry, industry, academia, and government sectors.

Opportunities

The successful deployment and evolution of the NII requires communications and information support services that are secure, reliable, scalable, fault-tolerant, easy-to-use, easy-to-manage, affordable, and deployed across a wide variety of technologies and media. Such systems will enable more people and businesses to use the NII for both personal and business advantages while building the critical mass necessary for moving to a post-industrial information-based society. In order to provide such a capability, research is particularly important in those areas that make it easy for the end-user to access the NII and its contents in a secure and private manner, that ensure the interconnectivity and interoperability of various technologies and services in a seamless fashion, that support real-time, distance-insensitive interactions and collaborations, and that support nomadic and local independent access.

Ongoing Activities

Advanced communications theory and algorithm research already initiated that must be pursued includes: analog and digital wireless services, micro to macro cellular systems, scalable, reliable, adaptive routing algorithms that support mobility and enhanced multicast capabilities, inter- and intra-enterprise security mechanisms, network resource allocation and management, all-optical switching and transmission techniques, wireless and satellite technologies, nomadic computing and access, internetworking and interoperable services, encoding and compression techniques, and support for electronic commerce.

New Efforts

Areas that require new or enhanced efforts include: universal accessibility, national digital wireless coverage, autonomous self-configuring network technology (plug and play), 100 gigabits per second network capability available generally, and terabits per second network capability available in the lab.

Challenges

Many challenges remain in the areas of: all optical switching; ubiquitous, multi-domain, and multi-level security; evolution of legacy systems and applications; global interoperability; ease-of-use; and NII user affordability, identification, and privacy.


A.3. Computing Systems

Goals

The goal of the Computing Systems area is to develop and demonstrate advanced computer systems and architectures offering very high performance, very low cost for a given level of performance, and very high performance in a small sized footprint, for a broad range of scientific, engineering, industrial, and national security applications.

Opportunities

A unifying opportunity for this area is the development and demonstration of balanced parallel systems that can gracefully scale across a wide range of underlying numbers of processor nodes and interconnection structures. The major issues in these developments are: insertion of ever more powerful processing nodes, incorporating hierarchical degrees of parallelism; faster interprocessor communications; global management of memory and data in cooperation with systems software; scalable, parallel input/output (currently a major bottleneck in recovering and interpreting the massive amounts of data produced by most high performance applications); and architectural convergence towards scalable parallel processing with support for vector processing, multiprocessing, message passing, and shared memory abstractions in a unified architecture.

Ongoing Activities

Activities contributing to balanced, scalable, parallel systems include more powerful processing nodes, faster interprocessor communications, global management of memory and data, scalable parallel input/output subsystems, and support for vector processing, multiprocessing, message passing, and shared memory abstractions in a unified architecture.

Architectural alternatives and processor, memory, interconnect, and I/O technology to support them are also being investigated and include scalable parallel systems and multicomputers, homogeneous and heterogeneous local-area clusters of commodity workstations, and distributed processing systems.

These advancements depend upon basic research that includes developing a fundamental understanding of architectural design, interconnection structures, computational complexity, and models of computation applied to parallel and distributed algorithms and systems. The theoretical underpinnings of computer-based aids for hardware and system design, such as reliability analysis, graph theory, and system timing methodologies, contribute to the science of computing system design.

New Efforts

New research and development is required that is focused on more specialized systems for supporting ubiquitous access, fault-tolerant highly available computing, real-time response in industrial and control applications, highly portable systems that can compute and communicate on the move, and other application-specific processors for tasks like signal processing. System support functions, such as security, reliability, resource scheduling, load balancing, performance instrumentation, and visualization are also being developed in support of this effort.

Challenges

The key challenge is to provide the technology to enable the low cost, ubiquitous systems required by user-centered interfaces and tools. One must be able to configure scalable systems over a wide performance range, spanning from workstation-class machines to networks of workstations to large scale parallel computing systems capable of teraoperations per second performance and beyond. System and application software that can gracefully scale across this range is also a key piece of this challenge.
