  • REDUCING PAGE INVALIDATION BROADCASTS IN VIRTUAL STORAGE MANAGEMENT
    Publication number: 20170123725
    Abstract: Technical solutions for reducing page invalidation broadcasts in virtual storage management are described. One general aspect includes a method including allocating, by a storage manager, a virtual memory page to a memory buffer that is used by an application being executed by a multiprocessor system, the virtual memory page being allocated from an address space of the application. The method also includes recording, by a memory management unit, a mapping between the virtual memory page and a physical location in a memory. The method also includes in response to a request, from the application, to deallocate the memory buffer, delaying invalidation of the mapping between the virtual memory page and the physical location in a memory, based on a count of free frames in the address space of the application.
    Type: Application

  • Storage management in a data processing system
    Patent number: 8458719
    Abstract: The invention relates to a method for storage management in a data processing system having a plurality of storage devices with different performance attributes and a workload. The workload is being associated with respective sets of data blocks to be stored in said plurality of storage devices. The method comprises the steps of dynamically determining performance requirements of the workload and dynamically determining performance attributes of the storage devices. The method further comprises the step of allocating data blocks to the storage devices depending on the performance requirements of the associated workload and the performance attributes of the storage devices.
