  • Patent number: 9984044
    Abstract: An approach is provided for predicting system performance. The approach predicts system performance by identifying a Queuing Network Model (QNM) corresponding to a clustered system that handles a plurality of service demands using a plurality of parallel server nodes that process a workload for a quantity of users. A workload description is received that includes server demand data. Performance of the clustered system is predicted by transforming the QNM to a linear model by serializing the parallel services as sequential services, identifying transaction groups corresponding to each of the server nodes, and distributing the workload among the transaction groups across the plurality of nodes. The approach further solves analytically the linear model with the result being a predicted resource utilization (RU) and a predicted response time (RT).

  • Patent number: 9986574
    Abstract: Techniques for channel selection and related operations in a shared spectrum environment are disclosed. In one example, a channel selector or the like may be used to select one of a number of available channels as an operating channel based on a comparison of cost functions for each of the available channels, with the cost functions being based on separate utility and penalty metrics. In another example, a channel scanner or the like may be used to trigger a channel scan in response to a channel quality metric indicating poor service for a threshold number or proportion of access terminals. In another example, an operating mode controller may be used to trigger a Time Division Multiplexing (TDM) mode on an operating channel in response to a utilization metric being above a threshold. The TDM mode may cycle operation between activated and deactivated periods in accordance with a TDM communication pattern.

  • Patent number: 9984009
    Abstract: A processor, such as a low-cost microcontroller unit, uses a DMA controller to facilitate direct memory transactions between hardware subsystems independently of the CPU. To enable those transactions to be carried out security, gateways are provided to the DMA controller and peripheral bridge. The gateways, which have access to multiple access policies, switch between those policies depending on a hardware context and/or subcontext, such as the bus master originating the transaction and/or the DMA channel associated with the transaction. The gateways are operable to administer those policies independently of the CPU. In various implementations, gateways are provided for the DMA controller, the peripheral bridge, and/or individual peripherals. The processor is able to support secure, fully containerized operations involving its peripherals without constant CPU intervention.

  • Patent number: 9984180
    Abstract: Described herein is an empirical model to estimate inflow performance relationship (IPR) of fishbone wells. A reservoir simulation model is formulated and initial values for a plurality of reservoir and fishbone well parameters are assigned. IPR curves are generated by simulating the formulated reservoir model for a predetermined number of iterations. Each simulation iteration has a unique value of bottom-hole flowing pressure. Sensitivity analysis is performed based on the generated IPR curves by sequentially changing the values of the plurality of fishbone well parameters. Further, regression analysis is performed based on the sensitivity analysis in order to determine an empirical model that estimates the IPR of the fishbone well. The empirical model is determined as a function of a number of multilateral branches of the fishbone well.
