Performance Computing And Communications

Maintaining the United States' strong lead in information technology will require continued federal support of research in this area, most of which is currently funded under the High Performance Computing and Communications Initiative (HPCCI). The Initiative has already accomplished a great deal and should be continued. This book provides 13 major recommendations for refining both HPCCI and support of information technology research in general. It also provides a good overview of the development of HPCC technologies.

This book constitutes the refereed proceedings of the Second International Conference on High Performance Computing and Communications, HPCC 2006. The book presents 95 revised full papers, addressing all current issues of parallel and distributed systems and high performance computing and communication. Coverage includes networking protocols, routing, and algorithms, languages and compilers for HPC, parallel and distributed architectures and algorithms, wireless, mobile and pervasive computing, Web services, peer-to-peer computing, and more.

This book synthesizes the findings of three workshops on research issues in high-performance computing and communications (HPCC). It focuses on the role that computing and communications can play in supporting federal, state, and local emergency management officials who deal with natural and man-made hazards (e.g., toxic spills, terrorist bombings). The volume also identifies specific research challenges for HPCC in meeting unmet technology needs in crisis management and other nationally important application areas, such as manufacturing, health care, digital libraries, and electronic commerce and banking.

In 1991 the Federal Government initiated the multiagency High Performance Computing and Communications program (HPCC) to further the development of U.S. supercomputer technology and high-speed computer network technology. This overview by the Congressional Budget Office (CBO) concentrates on obstacles that might prevent the growth of the high-performance computing and data communications industries. The market for supercomputers, relative to that of other technologies, is small. The main obstacle to the rise of large commercial markets for HPCC-developed technology is that cheaper workstations may preempt further growth of the supercomputer market as a whole. In addition, an economic inertia may occur, as conventional supercomputers, working well, become difficult to dislodge in the marketplace. The National Research and Educational Network (NREN) is central to the HPCC program. The ways in which Internet is becoming the core of a national data network promise well for HPCC in the future, but HPCC technology might be precluded from having a substantial effect on the current markets if demand for high-speed communications does not emerge as envisaged by HPCC leaders. Cost considerations and policy directions for HPCC are discussed. Five tables, six figures, and one box illustrate the discussion. Three appendixes discuss HPCC technology spinoffs and speed calculations. (SLD)

This book constitutes the refereed proceedings of the Third International Conference on High Performance Computing and Communications, HPCC 2007. The 75 revised full papers address all current issues of parallel and distributed systems and high performance computing and communication, including networking protocols, embedded systems, wireless, mobile and pervasive computing, Web services and internet computing, and programming interfaces for parallel systems.
