To date, all plausible clocks have been designed to use fixed-sized time stamps, and the inaccuracy of these schemes varies from run to run. In this paper, we define a new met

We consider asynchronous shared-memory systems that are anonymous. The shared memory contains only the most common type of shared objects, read/write registers. We investigate, f

For implementations of the . object that use such primitives, we prove that the worst-case average number of steps performed by processes is Ω(log..), regardless of the value of ..
