Further important approaches are GLOBUS [10] and the World Wide Virtual Machine (WWVM,[11]) GLOBUS is a complete metacomputing toolkit based on a communication library called NEXUS. WWVM is a metacomputing environment with a web interface for configuration and management of computation servers. The interface is based on Common Gateway Interface (CGI) scripts, whereas the TENT system ....

....the effectiveness of our scheme in adapting to different client server capabilities for minimizing response times. Shifting computation from a server to its clients essentially scatters the workload around the world. This relates the global computing and application level scheduling projects [6, 7, 10]. Those projects deal with an integration of different machines as one virtual machine. Our experience in using bandwidth and load information for scheduling could be useful to this research. Addressing client configuration variation is discussed in [11] for filtering multi media data in order to ....
