An Improved k-Exclusion Algorithm

k-Exclusion is a generalization of Mutual Exclusion that allows up to k processes to be in the critical section concurrently. Starvation Freedom and First-In-First-Enabled (FIFE) are two desirable progress and fairness properties of k-Exclusion algorithms. We present the first known bounded-space k-Exclusion algorithm that uses only atomic reads and writes, satisfies Starvation Freedom, and has a bounded Remote Memory Reference (RMR) complexity. Our algorithm also satisfies FIFE, and has an RMR complexity of O(n) in both the cache-coherent and distributed shared memory models.
