Abstract

Described is an improved system, method, and computer program product for performing elections in a computing system. Approaches are described for the non-leader member of a member set to self-identify to be the vice-leader. When it detects a death, rather than wait the random, bounded period, the vice-leader can immediately send its 'vote for me' message to other members. This puts it ahead of the race by other members to announce their candidacies, and results in vastly more frequent conclusion of the election in the initial round.
