    摘要: Computerized methods, systems, and computer-storage media for throttling requests from virtual machines (VMs) to a hard-disk drive (HDD) are provided. When a request for disk I/O is received from a VM, a disk-drive model that simulates performance characteristics of the HDD is accessed. During access, the disk-drive model's estimation of HDD parameters and the disk-drive model's estimation of a current state of a disk head of the HDD are gathered. A projected execution time to carry out the request is computed as a function of the estimated HDD parameters and the estimated current state of the disk head. Also, an actual execution time to carry out the request is measured upon allowing the request to pass to the HDD. Using a comparison of the projected execution time and the actual execution time, the traffic of the requests from the VMs is throttled.

    摘要: Disclosed herein are representative embodiments of processing digital image data. In one exemplary embodiment disclosed herein, for a current block of a first frame of digital image data, a list of motion vector prediction information for the current block is populated with candidate motion vector prediction data that includes default motion vector prediction data. In another exemplary embodiment disclosed herein, at least a portion of a coded video bitstream is received and a merge flag for a current block in a current frame is decoded. After the merge flag is decoded, at least one merge candidate for the current block is determined.
