虚拟机调度算法对并行任务的执行效率考虑不够充分。现代处理器平台具备了多个可用的计算核心,使多个虚拟机并发执行成为了现实。针对多核平台下的并行虚拟机调度优化问题,提出一种基于任务特征虚拟机CON-Credit调度算法。该算法在调度并行任务时,使用动态方式对计算机核心进行分配,采用传统的虚拟机调度算法为执行普通任务的虚拟机进行分配；采用定制的同步算法给执行并行任务的虚拟机分进分配。相关实验显示,CON-Credit调度算法能显著提高并行任务的执行效率。
虛擬機調度算法對併行任務的執行效率攷慮不夠充分。現代處理器平檯具備瞭多箇可用的計算覈心,使多箇虛擬機併髮執行成為瞭現實。針對多覈平檯下的併行虛擬機調度優化問題,提齣一種基于任務特徵虛擬機CON-Credit調度算法。該算法在調度併行任務時,使用動態方式對計算機覈心進行分配,採用傳統的虛擬機調度算法為執行普通任務的虛擬機進行分配；採用定製的同步算法給執行併行任務的虛擬機分進分配。相關實驗顯示,CON-Credit調度算法能顯著提高併行任務的執行效率。
