Abstract

This article presents a solution to thefirst-come, first-enabledℓ-exclusionproblem of Fischer et al. [1979]. Unlike their solution, thissolution does not use powerful read-modify-write synchronizationprimitives and requires only bounded shared memory. Use of theconcurrent timestamp system of Dolevand Shavir [1989] is key in solving the problem within bounded sharedmemory.
