Organizations and enterprises have to constantly re-engineer and customize business processes to stay competitive in their market. These modifications and customizations result in a large number of similar processes that lead to high costs of deployment and maintenance. This paper presents a multi-layer architecture for efficient management of process variations. The approach consists of organizing...
This paper presents a time warp fossil collection mechanism that functions without need for a GVT estimation algorithm. Effectively each logical process (LP) collects causality information during normal event execution and then each LP utilizes this information to identify fossils. In this mechanism, LPs use constant size vectors (that are independent of the total number of parallel simulation objects)...
Optimistic time warp simulators should stop the rapid propagation of incorrect events to avoid reaching a catastrophic state (a state where out of order event execution is always a step ahead of its corrective measures). A distributed cancellation mechanism using total clocks was proposed earlier to avoid such catastrophic states. In this paper, we present a proactive cancellation mechanism using...
