LIGHTNING is a dynamically reconfigurable WDM network testbed project for supercomputer interconnection. This paper describes a hierarchical WDM-based optical network testbed that is being constructed to interconnect a large number of supercomputers and create a distributed shared memory environment. The objective of the hierarchical architecture is to(More)
– The objective of this paper is to develop a tool to study the interaction between the cache coherence protocol and the media access protocol for a multiprocessor system in a wavelength division multiplexed star-coupled configuration. This simulation is modular for easy swapping of component functional specifications, and inter-module communication is(More)
