This work addresses the leader election problem in distributed systems where processes can crash and recover. More precisely, it focuses on implementing the Omega failure detector class, which provides a leader election functionality, in the crash-recovery failure model. The concepts of quiescence and near-quiescence for an algorithm implementing Omega are defined. Depending on the use or not of stable...
This paper introduces Lamar University's Students Advancing through Involvement in Research Student Talent Expansion Program (STAIRSTEP), which is designed to increase the number of U. S. citizens receiving undergraduate degrees in science disciplines including computing, mathematics, physics, chemistry, geology and earth science. STAIRSTEP uses the experience gathered from two successful programs...
Unreliable failure detectors provide information about process failures. A particular failure detector called Omega has been shown to be the weakest for solving consensus with a majority of correct processes. This work addresses the implementation of Omega in the crash-recovery failure model. Firstly, the definition of Omega is adapted to that model, assuming that processes do not use stable storage...
