....a networked virtual supercomputer, wherein the distributed computational resources are used in a coordinated way, very much as though they were part of a single computer system. The potential of metacomputing has been demonstrated by the Global Information Infrastructure (GII) testbed at SC 95 [16].

....token must be handled by each system, the number of systems being monitored imposes a maximum frequency with which measurements can be taken. For small collections of machines it is adequate, but for larger scale systems such as the Distributed Object Computational Testbed (DOCT) 1] or the I way [11, 24] we will need another mechanism. 3.2 Storage Requirements Storage intrusiveness is also an issue. Some of the forecasting methods discussed in Section 4 require a history of measurements. In order to bound the storage requirements of the system, we limit the number of measurements each server is ....

....modeling of commercial engineering problems. An additional critical technology is the network infrastructure necessary to support the high bandwidth communication between remote collaborators; a prototype of such a network was demonstrated as part of the Information Wide Area Year (I WAY) (Korab and Brown, 1995) at the Supercomputing 95 (SC 95) conference. In this paper, we describe the development of a real time, interactive simulation and analysis environment used in the design of pollution control systems for commercial boilers and incinerators. The pollution control systems modeled in this project ....

The I WAY was built by linking supercomputing resources and advanced visualization devices around the country with a highbandwidth Asynchronous Transfer Mode (ATM) network. This platform represented an ideal testbed for examining the performance of the interactive and collaborative components of ....

....guiding a computation toward interesting phenomena) 5] Typically, application behavioral steering is interactive, with an application scientist studying near real time scientific visualizations and guiding the application code by changing key application variables. The Supercomputing 95 I WAY [5], with immersive visualizations of scientific computations, is the most recent and notable example. In contrast to the design of systems for steering computation behavior, there have been far fewer efforts [3, 14] to interactively steer or adaptively control application performance. Notably, ....

....high speed and high bandwidth networks connected to heterogeneous supercomputing resources and large data stores. Many of the applications in the GII Testbed at Supercomputing 95 focused on connecting supercomputing resources to VR devices to visualize data from specific scientific problem domains[1]. Our focus, however, was on researching the techniques required to support general collaborative work in persistent virtual environments. These techniques include providing: representations for virtual co presence; video and audio teleconferencing; virtual VR interfaces; and database technology ....
