Abstract
Communication‐induced checkpointing (CIC) protocols can be used to prevent the domino effect. Such protocols that belong to the index‐based category have been shown to perform more efficiently. In this paper, some results of comparing index‐based CIC protocols are proposed. First, we prove that comparing several protocols based on the lazy indexing strategy can be simply based on their checkpoint‐inducing conditions. Next, we show that improved indexing strategies may not always yield a better performance than the classical strategy. Finally, we present a simulation study to verify our foregoing theoretical results. The simulation is conducted in the typical point‐to‐point computational environment. Influences of enhancements on indexing strategies and checkpoint‐inducing conditions for index‐based CIC protocols are discussed.
