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)
