EIA-0101578Dan C. MarinescuPurdue UniversityCISE NGS: Middleware for Internet Workflow ManagementMiddleware is a software layer that allows applications to use the resources provided by a grid. The middleware is expected to perform functions provided by the operating system of a computer, e.g. resources management and process management. In case of a tightly coupled system, resource and process management is under the control of a scheduler, which manages and controls the allocation of all system resources to process competing for them. The scheduler has accurate information about the System State. The situation is quite different on a grid where resources are managed by autonomous entities and the scale of the system prevents any single entity from knowing accurately the state of the entire system. This proposal is concerned with middleware for process or workflow management.

EIA-0101578Dan C. Marinescu Purdue UniversityCISE NGS：Internet工作流管理中间件中间件是一个软件层，它允许应用程序使用网格提供的资源。 中间件被期望执行由计算机的操作系统提供的功能，例如资源管理和进程管理。 在紧耦合系统的情况下，资源和进程管理在调度器的控制下，调度器管理和控制所有系统资源向竞争它们的进程的分配。 调度程序具有关于系统状态的准确信息。 在网格中，情况完全不同，资源由自治实体管理，系统的规模阻止任何单个实体准确地知道整个系统的状态。 这个建议是关于过程或工作流管理的中间件。
