Abstract: Techniques are provided for dynamically implementing quality of service policies for a distributed storage system based upon resources saturation. A quality of service policy is defined for throttling I/O operations received by a node of the distributed storage system based upon whether resources of the node have become saturated. The quality of service policy is dynamically implemented based upon ever changing resource utilization and saturation. Dynamically implementing the quality of service policy improves the ability to efficiently utilize resources of the node compared to conventional static polices that cannot adequately react to such changing considerations and resource utilization/saturation. With conventional static policies, an administrator manually defines a minimum amount of guaranteed resources and/or a maximum resource usage cap that could be set to values that result in inefficient operation and resource starvation.

Abstract: Techniques are provided for dynamically implementing quality of service policies using a configurable quality of service provider pipeline. A quality of service policy is defined for throttling I/O operations received by a node based upon whether resources of the node have become over utilized. The quality of service policy is used to dynamically construct a quality of service provider pipeline with select quality of service providers that improve the ability to efficiently utilize resources compared to conventional static polices that cannot adequately react to changing considerations and resource utilization/saturation. With conventional static policies, an administrator manually defines a minimum amount of guaranteed resources and/or a maximum resource usage cap that could be set to values that result in inefficient operation and resource starvation. Dynamically constructing and utilizing the quality of service provider pipeline results in more efficient operation and mitigates resource starvation.

Abstract: A block of a video frame can be encoded using inter-prediction, and the motion vector of the block can be encoded based on a motion vector reference of a merge candidate. Some video codecs allow a large range of temporal and spatial neighbors to be considered as potential merge candidates. It is not practical to perform motion compensation and rate-distortion optimization for all possible merge candidates. To address this concern, a hardware-efficient process can be implemented to rank and select merge candidates. A reference frame priority list is applied to select a subset of potential reference frame combinations. An efficient top-K sorting algorithm is applied to identify merge candidates for each reference frame combination and keep top merge candidates with highest weights. Motion compensation and rate-distortion optimization are performed on the top merge candidates only.
