This paper attempted to decentralize volunteer computing (VC) coordination with the goal of reducing the reliance on a central coordination server, which had been criticized for performance bottleneck and single point of failure. On analyzing the roles and functions that the VC components played for the centralized master/worker coordination model, this paper proposed a decentralized VC coordination framework based on distributed hash table (DHT) and peerto-peer (P2P) overlay and then successfully mapped the centralized VC coordination into distributed VC coordination. The proposed framework has been implemented on the performance-proven DHT P2P overlay Chord. The initial verification has demonstrated the effectiveness of the framework when working in distributed environments.
