A Simulation Environment Based on the Sharing of Capacity from Privately Owned Workshops

正在开发利用私有工作站集群资源的策略，同时确保对工作站所有者很少或没有干扰。通过建立一个利用工作站所有者使用特点的模拟环境，所有用户都能享受到服务质量的提高。该系统将使用户能够向系统提交模拟模型的项目描述，他们将从该系统获得结果的图形显示。项目描述包括要执行的模拟作业的规范、项目的时间限制和作业的特征。需要开发和评估的一个重要特性是系统的截止日期驱动调度功能。模拟作业将被安排在作业时间限制的最后期限内进行。此外，调度器将允许为用户分配空闲工作站的分区，用于开发分布式应用程序。为了提供满足最后期限和分配空闲工作站分区的调度策略，正在开发工作站使用特征的工作负载模型。

Strategies for exploiting the resources of a privately owned workstation cluster while insuring little or no interference to the owners of workstations are being developed. By building a simulation environment that takes advantage of the usage characteristics of workstation owners, improvements of the quality of service is enjoyed by all users. The system will enable users to submit project descriptions of simulation models to the system from which they will receive graphical displays of the results. The project descriptions include a specification of the simulation jobs to be executed, the time constraints of the project, and characteristics of the jobs. An important feature to be developed and evaluated is the system's deadline-driven scheduling facility. Simulation jobs will be scheduled to meet the deadlines of the time constraints imposed on the jobs. In addition, the scheduler will allow users to be allocated partitions of idle workstations for developing distributed applications. In order to provide scheduling strategies for meeting deadlines and allocating partitions of idle workstations, workload models of the usage characteristics of workstations are being developed.
