This paper reviews issues concerning the design of adaptive protocols for parallel discrete
event simulation (PDES). The need for adaptive protocols are motivated in the background …

To make recommendations for improving requirements engineering processes, it is critical to
understand the problems faced in contemporary practice. We describe a field study whose …

This paper describes a new, auto-adaptive algorithm for dead reckoning in DIS. In general
dead-reckoning algorithms use a fixed threshold to control the extrapolation errors. Since a …

In a distributed memory environment the communication overhead of Time Warp as induced
by the rollback procedure due to “overoptimistic” progression of the simulation is the …

Recent papers have shown that the performance of Time Warp simulators can be improved
by appropriately selecting the positions of checkpoints, instead of taking them on a periodic …

Output production and predicate detection are critical in speculative parallel discrete event
simulation, since they need to take place accessing past state values—which have become …

Excessive rollback recoveries due to overoptimistic event execution in Time Warp simulators
often degrade their runtime performance. This paper presents a two-sided throttling scheme …

This paper presents a sparse state saving scheme for Time Warp parallel discrete event
simulation. The scheme bases the selection of the states to be recorded on the event history …

It is well known that Time Warp may suffer from poor performance due to excessive rollbacks
caused by overly optimistic execution. Here we present a simple flow control mechanism …

We present an algorithm which integrates flow control and dynamic load balancing in order
to improve the performance and stability of Time Warp. The algorithm is intended for use in a …
