We have designed and implemented an open, market-based computational system called Spawn. The Spawn system utilizes idle computational resources in a distributed network of heterogeneous computer workstations. It supports both coarse-grain concurrent applications and the remote execution of many independent tasks. Using concurrent Monte Carlo simulations as prototypical applications, we explore issues of fairness in resource distribution, currency as a form of priority, price equilibria, the dynamics of transients, and scaling to large systems. In addition to serving the practical goal of harnessing idle processor time in a computer network, Spawn has proven to be a valuable experimental workbench for studying computational markets and their dynamics.

The mobility/cloud ecosystem aims to deliver infrastructure, platforms, and software as a service, enabling more people to benefit from ubiquitous information access. The culmination of 10 years' research converges on-demand applications with the infrastructure—servers, storage, networks, and client devices—to support cloud computing. [ABSTRACT FROM PUBLISHER]
