Multi-cluster co-allocation scheduling algorithms in virtual computing environment

Based on the core mechanisms of Internet-based virtual computing environment (iVCE), a novel architectural framework for the multi-cluster task co-allocation is proposed by introducing the autonomic scheduling elements, domain scheduling commonwealth and meta-scheduling executor. A new multi-cluster task scheduling schema based on the multi-cluster task execution performance model is presented. Four multi-cluster heuristic scheduling algorithms are provided. Experiments indicate the scheduler schema and the algorithms are effective in the objective function of makespan and average utilization.
