Autonomic Log/Restore for Advanced Optimistic Simulation Systems

Free registration required

Executive Summary

In this paper, the authors address state recoverability in optimistic simulation systems by presenting autonomic log/restore architecture. Their proposal is unique in that it jointly provides the following features: log/restore operations are carried out in a completely transparent manner to the application programmer, the simulation-object state can be scattered across dynamically allocated non-contiguous memory chunks, two differentiated operating modes, incremental vs. non-incremental, coexist via transparent, optimized run-time management of dual versions of the same application layer, with dynamic selection of the best suited operating mode in different phases of the optimistic simulation run.
