    摘要: A method, system, and computer program product for managing system resources within a data processing system. A resource management moderator (RMM) utility assigns a priority to each application within a group of management applications, facilitated by a RMM protocol. When a request for control of a particular resource is received, the RMM utility compares the priority of the requesting application with the priority of the controlling application. Control of the resource is ultimately given to the management application with the greater priority. If the resource is not under control of an application, control of the resource may be automatically granted to the requester. Additionally, the RMM utility provides support for legacy applications via a “manager of managers” application. The RMM utility registers the “manager of managers” application with the protocol and enables interactions (to reconfigure and enable legacy applications) between the “manager of managers” application and legacy applications.

    摘要: Embodiments of the invention relate to efficiently processing read transactions in a shared file system having multiple virtual machines. Each virtual machine in the file system has access to disk storage and local disk cache. At the same time, each virtual machine in the file system has access to remote disk cache of a remote virtual machine. For each read transaction, the local and/or remote disk cache employed for data blocks to support the transaction. Disk storage is employed to support the transaction in the event that the data blocks are not available in the local and/or remote disk cache.

    摘要: Each time a currently scheduled virtual machine (VM) accesses a hardware resource over a bus for the hardware resource via the currently scheduled VM running on a processor, a hardware component adjusts a bandwidth counter associated with usage of the bus for the hardware resource, without involvement of the currently scheduled VM or a hypervisor managing the currently scheduled VM. Responsive to the bandwidth counter reaching a threshold value, the hardware component issues an interrupt for handling by the hypervisor to maintain bandwidth quality-of-service (QoS) of bus bandwidth related to the hardware resource. Upon expiration of a regular time interval prior to the bandwidth counter reaching the threshold value, the hardware component resets the bandwidth counter to a predetermined value associated with the currently scheduled VM, without involvement of the currently scheduled VM or the hypervisor; the hardware component does not issue an interrupt. The hardware resource can be memory.

    摘要: A computer implemented method for control access to a contested resource. When a lock acquisition request is received from a virtual machine, the partition management firmware determines whether the lock acquisition request is received within a preemption period of a time slice allocated to the virtual machine. If the lock acquisition request is received within the preemption period, the partition management firmware ends the time slice early, and performs a context switch.
