  • Patent number: 10489086
    Abstract: A data storage system includes a non-volatile memory array controlled by a controller that records a number of a plurality of like operations targeting a first block among a plurality of blocks in the non-volatile memory array. In response to the number of the plurality of like operations satisfying a threshold, the controller initiates a mitigation read request by recording an identifier of a second block in a high priority request in a mitigation data structure. The controller initiates other mitigation read requests by recording identifiers of other blocks of the non-volatile memory in low priority requests in the mitigation data structure. The controller preferentially services the high priority request from the mitigation data structure over the low priority requests, where servicing the high priority request includes performing a mitigation read to the second block.

  • Patent number: 9026422
    Abstract: Mechanisms are provided for controlling a fidelity of a simulation of a computer system. A model of the system is received that has a plurality of components. A representation of the plurality of individual components of the system is generated. A component is assigned to be a fidelity center having a highest possible associated fidelity value. Fidelity values are assigned to each other component in the plurality of individual components based on an affinity of the other component to the fidelity center. The system is simulated based on assigned fidelity values to the components in the plurality of individual components.

  • Patent number: 8437993
    Abstract: Mechanisms are provided for controlling a fidelity of a simulation of a system. A model of the system is received, the model of the system having a plurality of individual components of the system. Fidelity values are assigned to models of the individual components of the system. A simulation of the system is executed using the model of the system and the models of the individual components of the system. For each component in the plurality of individual components of the system, an activity level of the component during execution of the simulation is determined. The fidelity values of one or more of the models of the individual components of the system are dynamically adjusted during the execution of the simulation based on changes in individual activity levels of the individual components.

    Abstract: Mechanisms are provided for controlling a fidelity of a simulation of a system. A model of the system is received, the model of the system having a plurality of individual components of the system. Fidelity values are assigned to models of the individual components of the system. A simulation of the system is executed using the model of the system and the models of the individual components of the system. The fidelity values of one or more of the models of the individual components of the system are dynamically adjusted during the execution of the simulation by creating a checkpoint of a state of the simulation and modifying one or more fidelity values of one or more of the models of the individual components after generating the checkpoint, thereby generating a modified fidelity value state.

  • Patent number: 8407035
    Abstract: Mechanisms are provided for controlling a fidelity of a simulation of a system. A model of the system is received, the model of the system having a plurality of individual components of the system. Fidelity values are assigned to models of the individual components of the system. A required fidelity value is assigned to transactions between components in the plurality of individual components of the system. A simulation of the system is executed using the model of the system and the models of the individual components of the system. The fidelity values of one or more of the models of the individual components of the system are dynamically adjusted during the execution of the simulation based on the required fidelity values assigned to the transactions.

  • Patent number: 8290758
    Abstract: Mechanisms are provided for controlling a fidelity of a simulation of a system. A model of the system is received, where the model has a plurality of individual components of the system. Fidelity values are assigned to models of the individual components of the system and a simulation of the system is executed using the model of the system and the models of the individual components of the system. The simulation comprises a plurality of transactions targeting a receiver component. A history of mismatches between a fidelity value associated with the receiver component and required fidelity values of the plurality of transactions targeting the receiver component is maintained. A prediction of a fidelity value to be assigned to the receiver component based on the history of mismatches is performed. A fidelity value of the receiver component is adjusted based on results of predicting the fidelity value to be assigned to the receiver component.
