The Pessimism behind Optimistic
In this paper we make an analogy between the time that storage must be maintained in a optimistic simulation and the blocking time in a conservative simulation. By exploring this analogy, we design two new Global Virtual Time (GVT) protocols for Time Warp systems. The rst protocol is based on null message clock advancement in conservative approaches. Our main contribution is a new protocol insp...
متن کاملOptimistic Trace-driven Simulation
Parallel simulation of multiprocessor architectures is a promising direction because a parallel system provides the high computation and storage capabilities that are required by detailed architectural simulation. Additionally, the behavior of the target system exhibits natural parallelism. In this paper, we consider the evaluation of the memory hierarchy of multiprocessor systems via parallel ...
متن کاملScalable Optimistic Parallel Simulation
Computer simulation of large and complex systems in various elds of science and engineering requires tremendous computational resources, and is limited by sequential simulation algorithms in most practical cases. Parallel simulation ooers the potential to accelerate simulations so as to facilitate the study of complex dynamic systems with large problem sizes, to explore large parameter spaces, ...
متن کاملOptimistic Real-Time Simulation
On-line simulations play a critical role in understanding, supervising, and controlling large-scale systems. For instance, in military training applications, users are presented with complex scenarios that consist of both actual and simulated devices interacting in real-time. Troubleshooting of complex telephone networks may utilize on-line simulations to play`what if' games when evaluating alt...
متن کاملTowards large scale optimistic VLSI simulation
In this paper, an optimistic parallel and distributed logic simulator, XTW, is proposed. In XTW, a new event scheduling mechanism, XEQ, and a new rollback procedure, rb-messages, are proposed for use in optimistic logic simulation. XTW groups LPs into clusters, and makes use of a multi-level queue, XEQ, to schedule events in the cluster. XEQ has an O(1) event scheduling time complexity. Our new...
