The Computational Structure of Progress Conditions

摘要

Understanding the effect of different progress conditions on the com-putability of distributed systems is an important and exciting research direction. For a system with n processes, we define exponentially many new progress conditions and explore their properties and strength. We cover all the known, symmetric and asymmetric, progress conditions and many new interesting conditions. Together with our technical results, the new definitions provide a deeper understanding of synchronization and concurrency.
