摘要： An infrastructure including a cluster-global dispenser that evaluates resource consume requests against cluster-global resource management policies facilitates flexible and extensible monitoring and/or control of resource consumption for multiple and/or multi-component applications on a cluster of interconnected computers. Such an infrastructure facilitates application of comprehensive resource management to cluster computing, and compatibility with the level of abstraction offered by modern object-oriented languages. Such an infrastructure also maintains backwards-compatibility. Building on the foundation of a well-defined isolated component, the resulting resource management framework is capable of supporting a rich collection of resources and of defining policies. The notion of a cluster-global resource naturally captures the aggregation of node-local resource. This applies the familiar “single system image” attribute of cluster systems to the area of resource management. The ability to associate the multiple components (isolates) of a distributed application with a single resource domain (policy), dramatically simplifies resource accounting for cluster applications.
摘要翻译：包括集群全局分配器的基础设施，用于评估针对集群全局资源管理策略的资源消耗请求，有助于在互连计算机集群上的多个和/或多组件应用程序的资源消耗的灵活和可扩展的监控和/或控制。这样的基础设施有助于集成计算的全面资源管理应用，以及与现代面向对象语言提供的抽象级别的兼容性。这样的基础架构也保持向后兼容性。基于明确界定的隔离组件的基础，由此产生的资源管理框架能够支持丰富的资源集合和定义策略。集群全局资源的概念自然地捕获了节点本地资源的聚合。这将集群系统中熟悉的单一系统映像属性应用于资源管理领域。将分布式应用程序的多个组件（隔离）与单个资源域（策略）相关联的功能大大简化了集群应用程序的资源计费。

摘要： A dynamic delegation chain of executor objects can, at runtime, adapt code units to be executed as isolated computations prior to their execution to comport with current state of an environment. A dynamic delegation chain performs the dynamic runtime adaptation of the code unit in accordance with isolated computations that host the executor objects of the delegation chain. Adapting a code unit prior to execution of the code unit allows adaptation of the code unit to a current state, as well as at least reducing concerns of program integrity.

摘要： System and method for supporting per-program classpath and class sharing in a multi-tasking virtual machine. A virtual machine may allow each program to specify its classpath independently of other programs classpaths. Tasks that specify identical classpaths for their respective class loaders may share the runtime representation of classes. A multi-tasking virtual machine may generate and compare canonical forms of classpaths to determine which programs may share classes with each other. The runtime representation of a class may be split between shared and private portions of the runtime representation. A shared runtime representation may be associated with multiple private runtime representations. In one embodiment, unique class loader keys and a system dictionary may be used to associate tasks, class loaders and the shared representations of classes.

摘要： Providing a resource domain structure allows flexible management of resources. With flexible management, computations, such as threads and processes, do not have to be related to be bound to the same resource domain. Since resource domains do not require the parent-child relationship, unrelated computations can bind each other to their resource domains. A data structure identifies a resource domain, the resource of the domain, and implementation of a resource management policy. The implementation of the resource management policy includes policy action, which when executed invoke policy imposing isolates. The resource domain data structure also indicates availability of usage of the resource.
摘要翻译：提供资源域结构可以灵活地管理资源。通过灵活的管理，计算（如线程和进程）不必与相同资源域绑定相关。由于资源域不需要父子关系，因此不相关的计算可以将其彼此绑定到其资源域。数据结构标识资源域，域的资源以及资源管理策略的实现。资源管理政策的实施包括政策行动，执行时采取政策强制隔离。资源域数据结构还指示资源的使用可用性。

摘要： Providing an intermediate isolate, referred to as a dispenser, to handle resource requests allows for monitoring and controlling of resource consumption separate from an operating system. Resources are characterized with a set of common attributes, separate from their specific implementation. The dispenser invokes computations that provide policy decisions corresponding to a resource request. The dispenser provides the requesting isolate a response based at least in part on the policy decisions. Separating management of resources from the operating system facilitates implementation of a dispenser in a safe language and management of a broad range of resources by the dispenser.

摘要： Controlling rate of resource consumptions improves manageability of resources in relation to the entities consuming the resource. A consumer's resource consumption behavior can be controlled with a mechanism that throttles its resource requests to conform to a threshold rate, such as a resource consumption rate. A set of one or more computations tracks a consumption measurement variable over a given time interval, such as number of resource requests for a given resource within the last 5 seconds. When a resource request is received, the set of computations determine whether servicing the resource request would exceed the threshold rate. If the threshold rate would be exceeded, then the computations sleep until servicing the resource request would not exceed the threshold rate.
摘要翻译：资源消耗的控制率提高了与消耗资源的实体相关的资源的可管理性。消费者的资源消耗行为可以通过限制其资源请求以符合阈值速率（例如资源消耗速率）的机制来控制。一组一个或多个计算在给定的时间间隔内跟踪消耗测量变量，例如在最近5秒内给定资源的资源请求数。当接收到资源请求时，该组计算确定服务资源请求是否超过阈值速率。如果超过阈值速率，则计算休眠直到服务资源请求不会超过阈值速率。

摘要： A system and method for isolating the execution of a plurality of applications. The applications may utilize or share one or more “original” classes. Only one copy of each original class is maintained, regardless of how many applications utilize it. Static fields are extracted from the original classes. A separate copy of the static fields is created for each of the utilizing applications. A static field class which includes instance fields corresponding to the static fields may be created, wherein each instance of the static field class corresponds to one of the utilizing applications. Access methods for the one or more static fields may be created, wherein the access methods are operable to access the corresponding separate copy of the static fields based upon the identity of the utilizing application. A single access methods class may be created for each original class, wherein the single access methods class includes the access methods for accessing the extracted fields from the original class. The method and system may be optimized by exempting from extraction static fields that are classified as secure for utilization by the plurality of applications without inter-application interference. The secure set of static fields may include final static fields of primitive types, final static strings, immutable arrays of primitive types, and/or other appropriate fields.

摘要： A system and method are provided for thread-safe initialization of static variables in a multitasking system. In one embodiment, the static fields of a class may be “virtualized” such that each application that utilizes the class has its own copy of static fields. Each separate copy of the static fields is initialized only once. Instructions for performing the initialization may be embedded in a class constructor. The class constructor may be executed only once for each separate copy of the static fields. A template class may be loaded for each separate copy of the static fields when a copy of the static fields is sought to be initialized. The template class may include a static initializer for one of the separate copies of the static fields. The static initializer may be executed once for each separate copy of the static fields.
