This paper presents a software based approach to fault-tolerant routing in oblivious, worm-hole routed networks. When a message encounters a faulty output link it is removed from the network by the local router and delivered to the messaging layer of the local node's operating system. The message passing software can reroute this message along a non-minimal(More)
Fault-tolerant routing protocols in modern interconnection networks rely heavily on the network flow control mechanisms used. Optimistic flow control mechanisms such as wormhole routing (WR) realize very good performance, but are prone to deadlock in the presence of faults. Conservative flow control mechanisms such as pipelined circuit switching (PCS)(More)

This paper describes the undergraduate computer architecture courses and laboratories introduced at Georgia Tech during the past two years. A core sequence of six required courses for computer engineering students has been developed. In this paper, emphasis is placed upon the new core laboratories which utilize commercial CAD tools, FPGAs, hardware(More)
In this paper, we extend the framework of Leland (1994b) who proposed a structural model of roll-over debt structure in a Black-Scholes framework to the case of a double exponential jump diffusion process. We consider a trade-off model with firm's parameters as firm risk, riskfree interest rate, payout rate as well as tax benefit of coupon payments, default(More)
In communication network, the number of nodes is continuously passing messages to each other in a particular fashion. Every node knows its neighboring peer. So, it is necessary to learn the topology of the entire network. Usually, in this type of network many resources are shared and deal with faulty components. Therefore, Fault tolerance is measure issue(More)
This paper presents a software based approach to fault-tolerant routing in networks using wormhole or virtual cut-through switching. When a message encounters a faulty output link, it is removed from the network by the local router and delivered to the messaging layer of the local node's operating system. The message passing software can reroute this(More)
