Nondominated k-Coteries for Multiple Mutual Exclusion
Quorum-based mutual exclusion algorithms are resilient to node and communication line failures. In order to enter its critical section, a node must obtain permission from a quorum of nodes. A collection of quorums is called a coterie. The most resilient coteries are called nondominated coteries. Recently, k-coteries were proposed to be used in mutual exclusion algorithms that allow up to k entr...
متن کاملThe Availability of Complemental k-Coteries
k-Coterie is a graceful concept to solve the distributed k-mutual exclusion problem. The k-mutual exclusion algorithm adopting k-coteries could provide the fault-tolerant capability. The complementalness and the availability are two important metrics to measure the fault-tolerant capability of a k-coterie. Since those two metrics are defined under two different failure assumptions, for a given ...
متن کاملProof of Berge's strong path partition conjecture for k=2
Berge’s strong path partition conjecture from 1982 generalizes and extends Dilworth’s theorem and the Greene–Kleitman theorem which are well known for partially ordered sets. The conjecture is known to be true for all digraphs only for k = 1 (by the Gallai–Milgram theorem) and for k ≥ λ (where λ is the cardinality of the longest path in the graph). The attempts made, so far, to prove the conjec...
متن کاملA Comparison of Two Torus-Based K-Coteries
We extend a torus-based coterie structure for distributed mutual exclusion to allow k multiple entries in a critical section. In the original coterie, the system nodes are logically arranged in a rectangle, called a torus, in which the last row (column) is followed by the first row (column) using end wraparound. A torus quorum consists of a head and a tail, where the head contains one entire ro...
متن کاملA Coterie Join Operation and Tree Structured k-Coteries
ÐThe coterie join operation proposed by Neilsen and Mizuno produces, from a k-coterie and a coterie, a new k-coterie. For the coterie join operation, this paper first shows 1) a necessary and sufficient condition to produce a nondominated k-coterie (more accurately, a nondominated k-semicoterie satisfying Nonintersection Property) and 2) a sufficient condition to produce a k-coterie with higher...
