英语翻译
Line 2 gives the computation time which is estimated as the Typical Execution Time stored in VEMR.Line 3 computes the time needed to transfer the input/output data,where inLatency/outLatency is the network latency of the input/output channel,inData/outData is the amount of the input/output data measured by bit and inBandwidth/outBandwidth is the bandwidth of the input/output channel.Line 4 and 5 gives the value of ExecTime where we give more power to CommuTime because communication time is prone to gain by reason of congestion.Finally rank is the reciprocal of ExecTime,which is the basis for selection.
Data Management Services (DMS)
The DMS is responsible for the search,collection,extraction,transformation and delivery of the data required or produced by the VI,analysis & visualization tools,and constraints computing tools.Data produced by a remote service may be either stored at the same host of the service executed or collected at a central database,or transferred to next service directly.This information is managed by DMS.DMS service is based on the Globus GridFTP,RFT and RLS services.The goal of DMS is to realize individual warehouse,a single,large,virtual warehouse of a VE data.It deploys a data grid for a VE.
High-Level VE Services Layer
This layer includes services used to search,select and access resources of the VE grid.Moreover,this layer offers services of result visualization.It is the programming interfaces for VE work bench and VEAES developers.Main services are as follows.
VI Access Services (VIAS)
This service is responsible for the search,selection,and deployment of distributed VIs,employing the services provided by VEDS and RAS.The VIs may be simulation software,or remote control physical instruments.The VIs may be implemented as java applet which could be downloaded to the client side,or a web service which will be run at server side or a grid service which will be executed in a Virtual Organization [1].No matter which kind it is,VI should have standard soft front panel.We don’t recommend java applet VIs,because they are difficult to communicate.
Tool Access Services (TAS)
This service is responsible for the search,selection,and deployment of distributed VE tools,employing the services provided by VEDS and RAS.The tools may provide services for data analysis and management,VE constraint computing,and data visualization.
Result Presentation Services (RPS)
Result visualization is a significant step in the VE process that can help students in the VE result interpretation.This service specifies how to generate,present and visualize the data produced by VI and analysis tools.The result could be recorded and stored either as XML format or visualization format.

线2给估计作为在VEMR存放的典型的执行时间的计算时间.线3计算时间需要转移输入-输出数据,inLatency/outLatency是输入输出通道的网络传输时间,inData/outData是位测量的相当数量输入-输出数据,并且inBandwidth/outBandwidth是输入输出通道的带宽.线4和5给ExecTime的价值,我们给更多力量CommuTime,因为通信时间是易受的获取根据壅塞的原因.最后等级是相互的ExecTime,是为选择的依据.
数据管理服务(DMS)
DMS负责对计算工具的VI需要或导致的数据的查寻、汇集、提取、变革和交付,分析&形象化工具和限制.一项远程服务导致的数据也许被存放在服务的同一个主人直接地被执行或收集在一个中央数据库或者转移到下项服务.这信息由DMS处理.DMS服务根据Globus GridFTP,RFT和RLS服务.DMS的目标是体会单独仓库,VE数据的一个唯一,大,真正仓库.它部署数据栅格为VE.
高级VE为层数服务
这层数包括用于的服务VE栅格的搜寻,精选和通入资源.而且,这层数提供结果形象化服务.它是编程接口为VE工作台和VEAES开发商.主要服务如下是.
VI通入服务(VIAS)
这项服务负责对分布的力的查寻、选择和部署,使用VEDS和RAS提供的服务.力也许是模仿软件或者遥控物理仪器.力也许被实施当可能被下载到客户端的java附属程序,或者将跑在服务器端或栅格的网服务服务在一个真正组织[1]将被执行.种类它是,VI应该有标准软的面板的不论.因为他们是难沟通,我们不推荐java附属程序力.
工具通入服务(TAS)
这项服务负责对分布的VE工具的查寻、选择和部署,使用VEDS和RAS提供的服务.工具也许为数据分析和管理提供服务,VE限制计算和数据形象化.
结果表示服务(RPS)
结果形象化是重大步在VE结果解释可能帮助学生的VE过程中.这项服务指定如何引起,提出和形象化VI和分析工具导致的数据.结果能被记录并且存放了当XML格式或形象化格式.
