    • A mechanism is provided for implementing multi-level resource control in operating system partitions. In one implementation, one or more non-global partitions may be established within a global operating system environment provided by an operating system. Each non-global partition may have one or more projects executing therein, and each project may comprise one or more processes. Each non-global partition may have associated therewith a first resource limit. This resource limit indicates how much of a particular resource has been allocated to the non-global partition as a whole. Each project executing within a non-global partition may have associated therewith a second resource limit. This limit indicates what amount of the particular resource allocated to the non-global partition has been allocated to that project. By setting multiple limits in this manner, it is possible to control resource allocation at multiple levels.
    • 提供了一种用于在操作系统分区中实现多级资源控制的机制。 在一个实现中,可以在由操作系统提供的全局操作系统环境内建立一个或多个非全局分区。 每个非全局分区可以具有在其中执行的一个或多个项目,并且每个项目可以包括一个或多个进程。 每个非全局分区可以与其相关联地具有第一资源限制。 该资源限制指示特定资源作为整体分配给非全局分区的数量。 在非全局分区内执行的每个项目可以与其相关联地具有第二资源限制。 此限制指示分配给非全局分区的特定资源的数量已分配给该项目。 通过以这种方式设置多个限制,可以在多个级别控制资源分配。

    • Methods, apparatus, and computer program products are disclosed for a process of dynamically adding new software having resource controls to an operating system and having the resource controls added to various resource control files in the operating system. The process also allows for a resource control to have an arbitrary number of limit values before a highest limit value is reached. A method of dynamically checking a resource control associated with newly added software to an operating system is described. A process or other type of entity in the operating system encounters newly added software and its associated resource control. The operating system then determines whether the resource associated with the resource control is active. If so, the operating system then determines whether usage of the resource by the entity exceeds a limiting value stored in the resource control. If so, one or more actions related to the resource are triggered by the operating system. If the limiting value has not been exceeded, granting the resource to the process or entity. At this time, the operating system can reset the limiting value of the resource control to another threshold value. In this manner, the process can have an arbitrary number of limiting values associated with the resource control.

    • Systems and methods of user-space resource management. Resource usage of a workload is monitored outside of an operating system space. Alternatively, resource usage of a workload can be monitored from within the workload. A resource monitor scans a plurality of workloads to determine if a workload exceeds a resource capacity limit. The resource monitor can also determine if a workload exceeds a threshold limit that is less than the resource capacity limit. The resource monitor can initiate a process in user space to reduce the workload's resource usage. Monitoring resource usage from outside of an operating system space enables optimization of computing resources dedicated to resource usage monitoring. In a virtual memory operating system, a user-space resource monitor can perform selection of pages for paging.
    • 用户空间资源管理的系统和方法。 在操作系统空间之外监视工作负载的资源使用情况。 或者,可以从工作负载中监视工作负载的资源使用情况。 资源监视器扫描多个工作负载以确定工作负载是否超过资源容量限制。 资源监视器还可以确定工作负载是否超过小于资源容量限制的阈值限制。 资源监视器可以启动用户空间中的进程,以减少工作负载的资源使用。 从操作系统空间外部监控资源使用可以优化专用于资源使用监控的计算资源。 在虚拟内存操作系统中,用户空间资源监视器可以执行寻呼页面的选择。
