Abstract : the processes concept is introduced in monolithic processor control system . date structure design and system scheduling for using processes scheduling to manage system sources are described in this paper 文摘:将多进程概念引入8098单片机控制系统中。重点描述了采用进程调度方式管理资源的数据结构设计及系统调度流程。
As for the poor method of dispatching in the past , the bus company provides bad bus operation , badly impacting the service quality and the social credit . in the same time it impacts its economic benefit 过去由于调度方式的落后，造成车辆运行秩序的混乱，严重影响了公共客运的服务质量和社会信誉，同时也直接影响其经济效益。
It has the unparalleled advantages . at present , most of clusters ’ scheduler polices adopt the centralized passive scheduler with the basic characteristic of centralized load evaluation , which mainly results in the inaccurate evaluation of server load 当前集群方案的调度方式都是采用以统一的负载评估结点为基本特征的集中式被动调度,带来的问题主要是服务器负载评估不尽准确。
The singlepoll scheme and the multipoll scheme are applied to realize polled txop . the simulations validated that polled txop can offer good parametered qos service . moreover , the advantage of multipoll scheme is proved by comparison of polling efficiency 对polledtxop ，分别利用singlepoll和multipoll两种调度方式实现，验证了其能够有效支持参数化qos ，并通过调度效率的比较，证明了multipoll调度的优越性。
Third , on the base of the improved architecture , two scheduling algorithms have been designed : acbs and cbstdm , which both are distributed traffic scheduling schemes and totally different from the traditional fabric scheduling schemes . the traditional fabric scheduling algorithms push the data towards egress ; however , acbs and cbstdm pull data from ingress . in acbs , ingress and egress transfer asynchronous control messages to finish distributed “ one - hop ” scheduling 再次,在改进结构基础上设计了两种调度算法acbs和cbstdm ,两种算法均属于流调度算法,采用分布式的调度方式,与传统的用于多级结构的集中式两次匹配的调度算法有很大的区别,传统算法将输入端口的数据包“推”向交换结构的输出端口,而acbs算法和cbstdm算法是通过输出调度器将数据包从输入端口“拉”向输出端口。
Finally , taking the panjiakou reservoir in the haihe river basin in china as an example , the paper analysis the reasonable adjustment scheme of the limited level of the reservoir during the flood season according to the design flood , the flood forecasting , the flood control operation under forecasting , the flood control standard of upstream and downstream of the reservoir , the immigrants range , and the benefits and the risk of the reservoir in a long period of the operation simulation 最后以海河流域潘家口水库为分析实例，从设计洪水、预报预泄、洪水预报调度方式、上下游防洪设计标准、上游移民淹没及土地退赔线、水库长期运行的风险和效益等多个方面分析论证了水库汛限水位的合理调整方案。
Quantity of generating electricity should be also calculated while the river inflow , quantity of water transfer and its duration curve are taken into account . as a company , it is necessary to take a series of measures to increase its benefits while water transfer leads to the decrease of hydro power inevitablly . the efficient methods can be taken into account as follows : i ) to improve the forecast accuracy , to decrease surplus water , and to increase seasonal electricity energy , ii ) to raise the peaking ability of dan jiang kou power station to obtain peaking benefits , iii ) to choose a suitable site to construct a pumped storage plant for peaking benefits 在进行以上四方面内容深入探讨的基础上，论文针对丹江口水利枢纽运行任务、运行方式的重大变化，提出汉江集团应采取以下因应措施以适应企业产业结构的调整，这些措施包括：准确计算发电效益减少值；合理地核算水源的供水成本；以上述两项计算成果为基础，核算企业结构调整后总效益变化量；提高预报水平，减少弃水量，争取增发季节性电能；研究新的调度方式，提高电站调峰能力，提高电站的容量效益；在适当的地点修建抽水蓄能电站，提高电站的调峰能力。
Combining with case study , the application conditions of hydrologic meteorology forecast information and flood forecast information in dynamic control of the limit water level during flood seasons are also illustrated . ( 3 ) in order to relieve the contradiction between water discharge in flood seasons and water shortage after flood seasons , the manner of flood operation with fixed limited water level during fixed time should be adjusted ( 3 )为改变水库汛期弃水而汛后又缺水的矛盾局面，调整现行水库固定时间固定汛限水位的调度方式，利用短期气象预报和洪水预报信息，在不改变现有防洪标准的前提下研究防洪预报调度方式，实现防洪与兴利效益的转换，提高洪水资源的利用率。
Traditional military strength scheduling solutions show some drawbacks , such as lower information degree , lower automation degree , worse collaboration , lower reliability , lower adaptability , lower flexibility , and etc . for these drawbacks , the traditional scheduling solutions can not meet the corresponding warfare needs under information conditions 传统的兵力调度方式存在信息化、自动化程度低,协调性、可靠性、适应性以及柔性差等问题,这些问题的存在使得传统的兵力调度手段不能适应信息化作战的需要。
This text has analysed load balancing method of existent especially lvs cluster system and recommended the net packet and netfilter ’ s frame structures in the linux operating system ; it has compared the cooperative - type - cluster with tradictional cluster in the net packets ’ queue ways and with active cluster in the load balancing dispatcher way , which has reflected the superiority of cooperation type cluster ; the three major parts of the cooperative - type - cluster have been designed and realized in this text , which includes sync packets ’ priority service for dmcs 、 “ priority and avoid sudden load unbalance ” dispatch way at the cooperation of nodal servers and director and active nodal server which ensure cluster normally running when cluster join or rduce node server ; the cooperative - type - cluster ’ s control frame controlled by homepage has been constructed ; the mulit - services cluster system has been realized ; this text has used the existing server pressure testing tools to test the cooperative - type - cluster and lvs cluster , then has comparaed and analysed the two 本文分析了现有服务器集群特别是lvs集群系统的负载均衡方法,介绍了linux系统下的报文和netfilter的框架结构;将所提出的合作式集群与传统集群在报文排队方式上进行比较,与主动式集群在负载均衡调度方式上进行比较,体现了合作式集群的优越性;设计并实现了合作式集群体系结构的三大部分:针对分布式测控系统的加权服务、负载均衡器与节点服务器合作式“加权防突”负载调度、保证集群运行不受加减节点干扰的主动性真实服务器;构建了通过网页界面控制合作式集群的控制框架;实现了一个可运行的合作式多服务集群系统,运用现有服务器压力测试工具对合作式集群和lvs集群进行负载测试,并对测试结果进行比较分析,同时通过压力测试实现加权服务。
