On the inherent weakness of conditional synchronization primitives Conference Paper uri icon


  • Abstract The" wait-free hierarchy" classifies multiprocessor synchronization primitives according to their power to solve consensus. The classification is based on assigning a number n to each synchronization primitive, where n is the maximal number of processes for which deterministic wait-free consensus can be solved using instances of the primitive and read write registers. Conditional synchronization primitives, such as Compare-and-Swap and Load-Linked/Store-Conditional, can implement deterministic wait-free consensus for …
