Optimistic protocols designed for Parallel Discrete Event Simulation (PDES) rely heavily on the Global Virtual Time (GVT) calculation. Since the simulation uses large amounts of memory , the GVT is used to synchronize processes and discard obsolete system information. In this paper we present a new algorithm, the Continuously Monitored Global Virtual Time (CMGVT). Unlike others, this algorithm ...

To the Editor: An important study by Savilampi et al.1 demonstrating the rate of pulmonary aspiration in adults undergoing monitored anesthesia care with remifentanil was recently published in AneStheSiology. There is an important limitation of the study worth considering when interpreting the study results. The method of aspiration detection does not differentiate between pharyngeal-to-pulmona...
