Software environments which simulate the behavior of complex systems often lead to a computational expense that reaches the limit of hardware resources. The \conventional" approach partitions the global system program into a set of successively called sub-programs, where the programmer is responsible for scheduling and synchronization of all subprograms. Increasing the complexity of the global ...

Harness is an experimental metacomputing system based upon the principle of dynamic reconfigurability both in terms of the computers and networks that comprise the virtual machine, and in the services offered by the virtual machine itself. In this paper we describe how the capability to reconfigure the virtual machine plugging services on demand can be exploited to design dynamically reconfigur...

The data must be exchanged in real time, with level of fidelity sufficient to permit their acceptable representation by all other participating simulators. The question "what is sufficient?" requires a detailed understanding of the purpose for which DVS is being used. For training applications it turns out that a three-dimensional rendering with visual fidelity similar to that of an arcade or h...

Many simulation problems can take advantage of distributed simulation approach when dealing with the huge timeor spacecomplexity and the conventional sequential solution is not satisfying. We have proposed and implemented an object-oriented toolset for developing both sequential and conservative distributed simulation architectures, based on a sound formal background and our previous experience...
