Java enabling collaborative education, health care, and computing

Web technologies – in particular linked Java servers and clients – allow new dynamic collaborative environments linking people and computers. We describe the architecture of a system, TANGOsim, that combines a Java collaborative environment with an executive providing general message filters, and an event-driven simulator. The initial application is to command and control, but we describe how this approach can also be used in other areas, such as health care, scientific visualization and (distance) education.

Component architecture for building Web-based synchronous collaboration systems

Competent technology gains popularity as its benefits, the reusability and simplicity of use become more and more evident. We demonstrate how component technology can be effectively applied to the process of building collaborative applications in the Web environment. In order to support development of collaborative tools, the components must satisfy a set of requirements inherent for a synchronous collaboration environment. The distribution of arbitrary events and objects, the access to the collaborative session state, and the means of synchronizing operations on the shared resources must be provided. Tango Beans is a set of components based on the Tango Interactive framework that has been implemented to facilitate rapid development of collaborative applications. We explain how Tango Beans work and how they can be used to develop collaborative tools for synchronous distance learning and Web conferencing.

The Living Textbook and the K-12 Classroom of the Future

The Living Textbook creates a unique learning environment enabling teachers and students to use educational resources on multimedia information servers, supercomputers, parallel databases, and network testbeds. We have three innovative educational software applications running in our laboratory, and under test in the classroom. Our education-focused goal is to learn how new, learner-driven, explorative models of learning can be supported by these high bandwidth, interactive applications and ultimately how they will impact the classroom of the future.

MOVIE model for open systems based high performance distributed computing

MOVIE (multitasking object-oriented visual interactive environment) is the new software system for high performance distributed computing (HDPC), currently in the advanced design and implementation stage at Northeast Parallel Architectures Center (NPAC), Syracuse University. MOVIE System is structured as a multiserver network of interpreters of high-level object-oriented programming language MovieScript. MovieScript derives from PostScript and extends it in the C++ syntax based object-oriented interpreted style towards 3D graphics, high performance computing and general purpose high level communication protocol for distributed and MIMD-parallel computing. The authors describe the overall open systems based MOVIE design and itemize currently implemented, developed and planned components of the system.<<ETX>>

InfoMall: A Scalable Organisation for the Development of High-Performance Computing and Communications - Software and Systems

InfoMall is a programme lead by the Northeast Parallel Architectures Center (NPAC) featuring a partnership of over twenty-five organisations and a plan for accelerating development of the High Performance Computing and Communications (HPCC) software and systems industry. HPCC (or HPCN as it is known in Europe) is a critical technology which will have unprecedented impact on industry, education, society, and defense. Acceptance of HPCC by these real world sectors is held up by the extremely hard problem of HPCC software development. InfoMall employs a novel technology development strategy involving closely linked programmes in technology execution and certification, software development, marketing, education and training, economic development and small business support. InfoMall has excellent HPCC and other facility infrastructure. InfoMall partners have unrivaled expertise in all the areas critical to rapid development of the HPCC software industry. The process is constructed and explained by analogy to the full-service set of stores found in a shopping mall. InfoMall is a concept which can create 15,000 jobs in New York State alone, and be scaled in future years to create an order of magnitude more jobs nationally.

MOVIE model for open‐systems‐based high‐performance distributed computing

MOVIE (Multitasking Object-oriented Visual Interactive Environment) is a new software system for high-performance distributed computing (HPDC), currently in the advanced design and implementation stage at Northeast Parallel Architectures Center (NPAC), Syracuse University. The MOVIE system is structured as a multiserver network of interpreters of the high-level object-oriented programming language MovieScript. MovieScript derives from PostScript and extends it in the C++ syntax-based object-oriented interpreted style towards 3D graphics, high-performance computing and general-purpose high-level communication protocol for distributed and MIMD-parallel computing. The paper describes the overall open systems-based MOVIE design and itemizes currently implemented, developed and planned components of the system.

The electronic InfoMall - HPCN enabling industry and commerce

We describe our InfoMall technology transfer program — a partnership of over sixty commercial, academic and federal organisations working together on HPCN technology development as well as HPCN-enabled business activities. We discuss a selection of some of the project activities being undertaken by InfoMall members and focus on an “Electronic InfoMall” activity in collaboration with the US Air Force to exploit high performance computing (HPC) systems and software shared between collaborating members of a virtual organisation. This system is built around the World Wide Web — a protocol developed in Europe for the exchange of multimedia hypertext. We have demonstrated how HPC systems can be linked together using this mechanism, to provide networked services such as Video on Demand and Simulation on Demand. More information on InfoMall is available on the World Wide Web at http://www.infomall.org/.
