SUPPLEMENTARY INFORMATION:

Background: Scientific Discovery Through Advanced Computing

Advanced scientific computing will be a key contributor to scientific research in the 21st Century. Within the Office of Science (SC), scientific computing programs and facilities are already essential to progress in many areas of research critical to the nation. Major scientific challenges exist in all SC research programs that can best be addressed through advances in scientific supercomputing—designing materials with selected properties, elucidating the structure and function of proteins, understanding and controlling plasma turbulence, and designing new particle accelerators. To help ensure its missions are met, SC is bringing together advanced scientific computing and scientific research in an integrated program entitled “Scientific Discovery Through Advanced Computing.”

The Opportunity and the Challenge

Extraordinary advances in computing technology in the past decade have set the stage for a major advance in scientific computing. Within the next five to ten years, computers that are 1,000 times faster than today's computers will become available. These advances herald a new era in scientific computing. Using such computers, it will be possible to dramatically extend our exploration of the fundamental processes of nature (e.g., the structure of matter from the most elementary particles to the building blocks of life) as well as advance our ability to predict the behavior of a broad range of complex natural and engineered systems (e.g., the earth's climate or an automobile engine).

To exploit this opportunity, these computing advances must be translated into corresponding increases in the performance of the scientific codes used to model physical, chemical, and biological systems. This is a daunting problem. Current advances in computing technology are being driven by market forces in the commercial sector, not by scientific computing. Harnessing commercial computing technology for scientific research poses problems unlike those encountered in previous supercomputers, in magnitude as well as in kind. As noted in the 1998 repor t[1] from the NSF/DOE “National Workshop on Advanced Scientific Computing” and the 1999 report [2] from the President's Information Technology Advisory Committee, this problem will only be solved by increasing investments in computer software—in research and development on scientific simulation codes as well as on the mathematical and computing systems software that underlie these codes.

Investment Plan of the Office of Science

To meet the challenge posed by the new generation of terascale computers, SC will fund a set of coordinated investments as outlined in the long plan for scientific computing, Scientific Discovery through Advanced Computing,[3] submitted to Congress on March 30, 2000. First, it will create a Scientific Computing Software Infrastructure that bridges the gap between the advanced computing technologies being developed by the computer industry and the scientific research programs sponsored by the Office of Science. Specifically, the SC effort proposes to:

  • Create a new generation of Scientific Simulation Codes that take full advantage of the extraordinary computing capabilities of terascale computers.
  • Create the Mathematical and Computing Systems Software to enable the Scientific Simulation Codes to effectively and efficiently use terascale computers.
  • Create a Collaboratory Software Environment to enable geographically separated scientists to effectively work together as a team and to facilitate remote access to both facilities and data.

These activities will be supported by a Scientific Computing Hardware Infrastructure that has been tailored to meet the needs of its research programs. The Hardware Infrastructure is robust, to provide the stable computing resources needed by the scientific applications; agile, to respond to innovative advances in computer technology that impact scientific computing; and flexible, to allow the most appropriate and economical resources to be used to solve each class of problems. Specifically, the SC proposes to support:

  • A Flagship Computing Facility, the National Energy Research Scientific Computing Center (NERSC), to provide the robust, high-end computing resources needed by a broad range of scientific research programs.
  • Topical Computing Facilities to provide computing resources tailored for specific scientific applications and to serve as the focal point for an application community as it strives to optimize its use of terascale computers.
  • Experimental Computing Facilities to assess the promise of new computing technologies being developed by the computer industry for scientific applications.

Both sets of investments will create exciting opportunities for teams of researchers from laboratories and universities to create new revolutionary computing capabilities for scientific discovery.

The Benefits

The Scientific Computing Software Infrastructure, along with the upgrades to the hardware infrastructure, will enable laboratory and university researchers to solve the most challenging scientific problems faced by the Office of Science at a level of accuracy and detail never before achieved. These developments will have significant benefit to all of the government agencies who rely on high-performance scientific computing to achieve their mission goals as well as to the U.S. high-performance computing industry.

Background: National Collaboratories and High Performance Networks

The current core programs in ASCR are intended to enhance the Department's ability to satisfy mission requirements through advanced technologies such as distributed computing, national collaboratories, high performance networks, remote access to facilities, and remote access to petabyte-scale datasets with complex internal structure. Within this context, the National Collaboratories and High Performance Networks Programs provide a coordinated program of technology research and development that leverages the strengths of computer and computational science research programs and partners with science application pilot projects. Likewise, these programs support the Scientific Discovery through Advanced Computing by enabling integration of multi-institutional, geographically-dispersed researcher into effective, efficient teams and by providing Start Printed Page 79352distributed computing environments and tools to support the use of remote computers and access to data and facilities.

Advances in high performance network capabilities and collaboration technologies are making it easier for large geographically dispersed teams to collaborate effectively. This is especially important for the teams using the major computational resources, data resources, and experimental facilities supported by DOE. With leadership from DOE, these geographically distributed laboratories or collaboratories have begun to play an important role in the Nation's scientific enterprise. The importance of collaboratories is expected to increase in the future. However, significant research questions must be addressed if collaboratories are to achieve their potential: namely, to enable remote access facilities that produce petabytes/year; to provide remote users an experience that approaches the same as “being there;” to provide remote visualization of terabyte to petabyte data sets from computational simulation; and to enable effective remote access to advanced scientific computers.

Solving the challenging network and distributed computing problems calls for new modalities of scientific research. Many scientific applications when deployed on existing networks fail to meet the end-to-end expectations for performance. This is especially true for distributed high-end applications such as remote visualization and high capacity data transfer. Recent advances in optical networks brought about by Dense Wave Division Multiplexing (DWDM) are resulting in unprecedented increases for bandwidth in the core networks. However, many challenging protocol engineering, traffic engineering, and high-performance middleware problems must be addressed before complex scientific high-end applications and collaboratories can benefit from this increase in bandwidth. Harnessing this bandwidth at the application level poses some important and challenging problems.

Research is needed to understand what services collaboratories require and how these services should be integrated with the large number of network devices and network-attached devices that must work together. Examples of the components and services that need to be integrated include: data archives on tape, high performance disk caches, visualization and data analysis servers, authentication and security services, directory services, network resources, and computational systems including the computer on a scientist's desk. All of these physical and software services must be tied together by common software framework building blocks or “middleware” to enable the collaboratories of the future to succeed.

Further, at the network level, research is needed for advanced services to develop advanced network services and tools to deliver high end-to-end performance to distributed scientific applications. There are several areas that can contribute to improving the end-to-end performance for secure multi-gigabits/sec transport that some of DOE's advanced scientific applications require. These include: enhancement of existing transport protocols, the development of accurate measurement and analysis techniques, and the network services that can provide online performance predictions.

These challenges will be addressed through an integrated program of fundamental research in high performance networking and collaboratory technologies in partnership with key scientific disciplines that provide the applications—the research may be focused for short-term results (within three years) or long term (five-years and greater). This announcement seeks applications in three areas:

1. Middleware: research and development projects that will address individual technology elements to enable universal, ubiquitous, easy access to remote resources or that will contribute to the ease with which distributed teams work together. Enabling high performance for scientific applications is an important consideration.

2. Collaboratory Pilots: research and development of enabling technologies that is integrated with and required by distributed scientific applications. An example of such a distributed application is the real-time data acquisition, reduction and visualization for macromolecular crystallography using a high intensity X-ray light source facility remotely. Another distributed application could be an extensive network measurement and analysis infrastructure employed to diagnose and predict end-to-end performance.

3. High Performance Network Engineering: research, development, and testing of advanced network protocols, traffic engineering, and network services that can significantly improve capabilities, end-to-end performance, and controllability of networks infrastructures designed to support distributed scientific applications.

To the extent that software and/or infrastructure development is involved, all applications to this notice should address the issues that characterize a successful research lifecycle. That is, technology transfer strategies should be provided for the transition of research code and/or infrastructure into robust production. Long term software evolution and maintenance and end user support should also be considered.

Integration of work efforts across all projects funded under this notice will occur following the awards, to preclude duplication of effort and to maximize leveraging and coordination. Projects are expected to work closely with other SciDAC teams, where identified during this integration. Coordination through a participatory management process will continue for the life of the projects.

Solicitation Emphasis Areas

1. Middleware technology research and development projects are to have certain characteristics. Products of this research and development are expected to provide services that interoperate and feature common interfaces. It should be easy to learn and use the tools. Applications in response to this notice should delineate an effective strategy for coupling with requirements from the scientific applications of the potential collaboratories. Applications in response to this notice should also provide a plan for software maintenance and support.

Middleware technology research and development projects that enable collaboration may focus on providing a broad set of tools or toolkits to support, but are not limited to, the following areas of interest:

  • Collaborative Visualization.
  • Collaborative Problem Solving Environments.
  • Real-time Analysis.
  • Group Collaboration.
  • Data Management.
  • Science Portals.
  • On-line Instrumentation.
  • Data Grids.

In addition, middleware technology research and development projects may address standard services and protocols that are needed to enable persistent, universal, and ubiquitous access to networked resources, such as, but are not limited to, the following: Start Printed Page 79353

  • Directory Services.
  • Authentication/Authorization Services.
  • Co-scheduling Distributed Resources.
  • Multicast and efficient broadcast capabilities.
  • Automatic resource discovery protocols.
  • Remote data access services.
  • Network-attached memory and storage systems.
  • Communications services.

For middleware technology research and development projects, it is estimated that between four and eight awards could be made in FY 2001, contingent upon the availability of appropriated funds. The scope of a single-focus project is expected to range from $150K to $500K.

Collaboratory pilots should have certain characteristics. The project should:

  • Address a problem of national scientific or engineering significance clearly related to the mission of DOE and have high visibility.
  • Involve geographically separated groups of personnel and/or facilities that are inherently required to collaborate or be used remotely for success of the project.

The project may:

  • Focus on developing and providing a set of middleware services needed by a broad set of applications requiring distributed computing capabilities.
  • Focus solely on advanced network development and testing such as a measurement and analysis infrastructure to accurately measure, calibrate, diagnose performance related problems, and predict the end-to-end performance of operational high-speed networks.

All responses to this notice must provide a plan for transition to sustaining activities and services for end users on completion of the project. The scope of a collaboratory pilot is expected to be about $0.5M to $2.5M total per year. This is the total for all the institutions participating and it is expected that a single institution would be funded at a level of no more than $600K. It is estimated that three to five awards will be made for this area during FY 2001.

It is also possible for middleware technology research and development projects and/or collaboratory pilots to address an element for evaluating systems and their impact on the process of science, namely identifying factors that facilitate or impede the adoption of technology.

2. High Performance Network Engineering is key to the DOE vision of collaborative scientific research environments in which geographically distributed research teams and computing resources are interconnected to form a virtual computing research environment. Emerging high-end scientific applications, when deployed on existing networks, fail to meet the expected end-to-end performance, latency, security, and guaranteed quality of service required for complex scientific investigations. The high-performance network program addresses these challenges in the current announcement by focusing in three major research areas of high performance network engineering:

  • Network Measurement and Analysis: Focuses on the fundamental issues of end-to-end performance through measurement and analysis.
  • High-performance Transport Protocols: Addresses the performance and security enhancement issues of traditional protocols operating in high-speed, high-performance networks.
  • Advanced Traffic Engineering Tools And Services: Deals with advanced tools and service for managing, differentiating, and controlling network traffic in order to satisfy the end-to-end performance objectives.

(a) Network Measurement and Analysis: Applications may address innovative scalable network measurement and analysis infrastructures, tools, services, etc., that can be used to accurately measure, calibrate, diagnose performance related problems, and predict the end-to-end performance of operational high-speed network networks. This may involve passive and active measurement, SNMP derived data, or a combination and may include, but not be limited to, the following:

  • Bandwidth estimation techniques for high-speed links (OC-12, OC-48).
  • Measurement infrastructures to collect, store, and analyze traffic traces.
  • Distributed agent architecture for network measurement and analysis.
  • On-line analysis and data mining of measured data.
  • Dynamic end-to-end path selection based on online analysis.
  • Measurement and calibration of transport protocol performance.

Applications focusing on measurement and analysis infrastructures are expected to work in close collaboration with DOE's Energy Science Network (ESnet) in the deployment measurement facilities. A network research testbed facility has been established, with the cooperation of ESnet, for experimental network research activities. Researchers requiring the use of this experimental facility are encouraged to work closely with the ESnet Research Support Subcommittee (ESRSC) chartered to coordinate the activities of the testbed. A complete description of this experimental facility can be found at http://www.es.net.

(b) High-Performance Transport Protocols: The performance expectation for the delivery of multi-gigabits/sec throughput to distributed scientific applications far exceeds the capability of current networks. This performance expectation raises some fundamental questions concerning the capability of conventional routing protocols optimized for low-speed, best-effort traffic. The current announcement addresses transport protocol performance issues by seeking innovative approaches that may include but are not be limited to the following:

  • Transport protocol measurement, tuning, and calibration tools.
  • Adaptive extensions of transport protocols for high-speed networks.
  • High-performance network traffic characterization.
  • Transport protocol parallelization at high-speed.

The objective is to reduce the contribution of transport protocol on end-to-end congestion. Potential applications must provide a sound mathematical analysis of the proposed enhancements when subjected to high-end scientific applications that potentially exercise its important features.

(c) Advanced Traffic Engineering Tools and Services: Addresses the resource and performance optimization of high-performance and high-speed networks, including advanced traffic management and control strategies, services, and tools that can be used for traffic differentiation and for steering traffic. Applications may focus on, but are not limited to, the following:

  • QoS-based routing and source routing.
  • Dynamic routing and traffic control.
  • Congestion notification and avoidance.
  • Bandwidth brokering services.
  • Advanced traffic management tools and services.
  • Simulation of large traffic flows.

Applications addressing these and other related issues should concentrate on those activities that lead to a significant improvement in end-to-end performance of applications running across high performance networks.

The high-performance network research program anticipates funding projects in these three areas in FY 2001. It should also be noted that a collaboratory pilot (as discussed under Start Printed Page 79354section 2.) may focus solely on advanced network development and testing such as a measurement and analysis infrastructure to accurately measure, calibrate, diagnose performance related problems, and predict the end-to-end performance of operational high-speed networks. The scope of a single project is expected to range from $150K to $500K.
