摘要本次研究是对云计算服务的一个具体实现,是对小规模云节点协同工作问题的一次探究,是对一个具有初步规模的云计算服务的一次优化。
这个云服务针对的案例则是以近年来尤为流行的ACM/ICPC国际大学生程序设计竞赛为背景,设计的一个在线判题系统的客户端。
这个判题系统可以在大量用户进行比赛的过程中,使用选手机器的闲置资源进行判题,以缓解服务器的压力。从而实现网络计算、分布式计算以及并行计算合并起来的云服务体系。
在学习和总结前人工作的基础上,本次研究的工作内容包括以下几点:64925
1.分析当前环境背景下的云计算资源调度现状,梳理云计算的概念,分类、应用、关键技术以及分布式处理框架技术。
2.掌握现有实例(即分布式判题系统)中所使用各项技术,构建并完善现有实例中的缺陷。
3.针对当前实例中存在的问题进行优化,包括调整整个服务上层所提供的接口,优化各模块之间通信所存在的冗余,以及对使用频率较高的数据进行缓存和加密解密处理等。

Title : research of some problems to cloud nodes working together
Abstract This study is a concrete implementation of cloud computing service , is an exploratory of small-scale cloud nodes work together , is an optimization of a cloud computing services with preliminary scale .
The case for cloud services is based on the International Collegiate Programming Contest which is particularly popular in recent years. The design is an online judge system , we call it OJ for short.
The OJ can enable a number of users to compete using the cilent computers' idle resources to judge and feedback so that ease the pressure on the server. In order to achieve network computing, distributed computing and parallel computing combined cloud service system.
On the basis of the previous work ,this study include the following ponints:
1.Analyzing the deployment and allocation conditons in current background ,Stating the concept , kinds , application and core tech which emphasized the distributing process framework technologies.
2. Grasp the technology of the existing instance , build and improve the existing instance defects.
3.A problem in this instance, a series of optimization, including the entire adjustment services are provided on the upper interface, to optimize the communication between the various modules, redundant information, the use of high frequency data to be cached and encrypted decryption processing. and so on
Keywords: Cloud computing , Resource allocation , Optimization ,
