基于负载预测的虚拟机资源优化分配方案

云计算环境下,为了提高主机资源利用率和保证性能,考虑了主机负载因素的影响,提出了一种基于负载预测的虚拟机资源优化分配方案。通过预测主机负载情况,过滤掉即将达到警告值的主机,保证主机性能,防止虚拟机因负载过重发生不必要的迁移;对参与分配的物理机进行资源最大化利用分配,提高物理主机的资源利用率。通过仿真实验对该方案进行验证。实验结果表明该方案在保证了主机性能的同时提高了资源利用率。

Particle swarm optimization algorithm for partner selection in virtual enterprise

Partner selection is a fundamental problem in the formation and success of a virtual enterprise. The partner selection problem with precedence and due date constraint is the basis of the various extensions and is studied in this paper. A nonlinear integer program model for the partner selection problem is established. The problem is shown to be NP-complete by reduction to the knapsack problem, and therefore no polynomial time algorithm exists. To solve it efficiently, a particle swarm optimization （PSO） algorithm is adopted, and several mechanisms that include initialization expansion mechanism, variance mechanism and local searching mechanism have been developed to improve the performance of the proposed PSO algorithm. A set of experiments have been conducted using real examples and numerical simulation, and have shown that the PSO algorithm is an effective and efficient way to solve the partner selection problems with precedence and due date constraints.
