The eld of computer simulation has been advanced by the availability of distributed computer platforms and software architectures which take advantage of those platforms. A great deal of eeort has gone into the development of distributed simulation environments and object-oriented simulation in military applications. The maturation process of these technologies has reached the point where it is...

The SciDAC2 accelerator project at SLAC aims to simulate an entire threecryomodule radio frequency (RF) unit of the International Linear Collider (ILC) main Linac. Petascale computing resources supported by advances in Applied Mathematics (AM) and Computer Science (CS) and INCITE Program are essential to enable such very large-scale electromagnetic accelerator simulations required by the ILC Gl...

This paper first addresses future simulations needs from a generic point of view and then from the viewpoint of major stakeholders within the simulation community. These stakeholders include the simulation software developer/vendor, the corporate end user, the government end-user, the researcher and the educator. We then describe or outline the set of capabilities that will be needed to design ...

Web technologies|in particular linked Java servers and clients|allow new dynamic collaborative environments linking people and computers (collaboratories). We describe the architecture of a system, TANGOsim, that combines a Java collaborative environment with an executive providing general message lters, and an event driven simulator. The initial application is to command and control, but we de...

Virtual Humans are artificial characters who look and act like humans, but inhabit a simulated environment. One important aspect of many virtual humans is their communicative dialogue ability. In this paper we outline a methodology for study of dialogue behavior and construction of virtual humans. We also consider three architectures for different types of virtual humans that have been built at...
