ILI: an adaptive infrastructure for dynamic interactive distributed applications

Addresses the middleware that is necessary to realize the construction of distributed laboratories in which scientists can construct and use complex computations and then analyze and share their results across geographically separated collaborations. We present a model of such middleware for heterogeneous distributed computing platforms and also show how middleware can dynamically adapt to changes in the behavior of instruments and end users. To address the demands of applications executing in a distributed laboratory, we have developed an infrastructure, called ILI (Interactivity Layer Infrastructure), that can dynamically adapt to changes in the behavior of the computational instruments and end users across a shared and dynamically changing set of computational nodes and networks.
