Abstract

With the advent of cheap and powerful hardware for workstations and networks, a new cluster-based architecture for Time Warp simulations has been envisioned. However, fine-grained Time Warp applications that communicate frequently are not the ideal candidates for such architectures due to their high latency communication costs. Hence, designers of fine-grained Time Warp applications on clusters are faced with the problem of reducing the high communication latency of the communication subsystem in such architectures. An efficient communication subsystem consumes a lower fraction of the processing cycles for communication operations and allows the majority of the processing cycles to be used by the application. This increases the performance of Time Warp applications. This thesis reduces the latency of the communication subsystem by selecting one of the following approaches: (i) reducing network latency by employing a higher performance network hardware (i.e., Fast Ethernet versus Myrine...
