W e are in the midst of, or perhaps at the beginning of, the development of a new concept of computing and computers that will significantly affect OR/MS. This development is summarized in the phrase " the network is the computer. " The focus and use is not an individual computer and its resources but a network of computers and resources, indeed, a network of all computers. This concept is clos...

Abstract. To fully utilize resources in computer center, virtualization techniques are getting popular and several systems are proposed for this purpose. However, they just provide set of virtualized nodes, not the ’virtual clusters’; i.e., they are not able to install and configure middlewares and tools that makes ’set of nodes’ into ’cluster’. Another problem is that they just virtualize node...

A fork-join processing network is a queueing in which tasks associated with job can be processed simultaneously. Fork-join networks are prevalent computer systems, healthcare, manufacturing, project management, justice and so on. Unlike the conventional networks, have synchronization constraints that arise because of parallel cause significant delays. We study scheduling multiple types shared r...

Data-intensive applications in the Condor High Throughput Computing environment can place heavy demands on network resources for checkpointing and remote data access. We have developed mechanisms to monitor, control, and schedule network usage in Condor. By managing network resources, these mechanisms provide administrative control over Condor’s network usage and improve the execution efficienc...

Differentiated Services and Integrated Services architectures rely on mechanisms to dynamically allocate network resources. Here, we investigate the feasibility of dynamically adjusting prices based on congestion. The pricing policy implements a distributed resource allocation to provide guaranteed bounds on packet loss and end-to-end delay for real-time applications. Distributed pricing roles ...
