  • Publication number: 20200343434
    Abstract: On a first superconducting layer deposited on a first surface of a substrate, a first component of a resonator is pattered. On a second superconducting layer deposited on a second surface of the substrate, a second component of the resonator is patterned. The first surface and the second surface are disposed relative to each other in a non-co-planar disposition. In the substrate, a recess is created, the recess extending from the first superconducting layer to the second superconducting layer. On an inner surface of the recess, a third superconducting layer is deposited, the third superconducting layer forming a superconducting path between the first superconducting layer and the second superconducting layer. Excess material of the third superconducting layer is removed from the first surface and the second surface, forming a completed through-silicon via (TSV).

  • Patent number: 10818052
    Abstract: Techniques for selecting an anomaly based on a context are disclosed. A set of metrics corresponding to communications with nodes of a computer system are identified. A set of insights are generated based on the set of metrics. A context for determining a primary anomaly is determined. A subset of metrics associated with the context are identified. A subset of insights that are generated based on the subset of metrics are identified. An insight is selected from the subset of insights as the primary anomaly. A visualization associated with the primary anomaly is presented at a user interface. One or more secondary anomalies may be concurrently presented with the visualization. Additionally, the primary anomaly, the selected visualization, and/or the secondary anomaly is used to determine a new context for selecting another primary anomaly. Hence, a series of primary anomalies may be selected, each primary anomaly being related to each other.

  • Publication number: 20200322138
    Abstract: Generally described, one or more aspects of the present application correspond to techniques for creating encrypted block store volumes of data from unencrypted object storage snapshots of the volumes. These encryption techniques use a special pool of servers for performing the encryption. These encryption servers are not accessible to users, and they perform encryption and pass encrypted volumes to other block store servers for user access. The encryption context for the volumes can be persisted on the encryption severs for as long as needed for encryption and not shared with the user-facing servers in order to prevent user access to encryption context.

  • Patent number: 10790668
    Abstract: A method for operating a wind turbine system, and associated system, provides real and reactive power to a grid. The wind turbine system includes a generator with a power converter and an integrated reactive power compensation device. A total reactive power demand (Qcmd) is made on the wind turbine system at a first grid state, and is allocated to generator reactive power (Qg) and compensation device reactive power (Qmvb). A first reactive power droop scheme is determined that includes a reactive power droop value applied to one or both of the control loops for (Qg) and (Qmvb) at the first grid state. Upon detection of a grid fault, the first reactive power droop scheme is changed to a second reactive power droop scheme by changing the reactive power droop values applied to one or both of the (Qg) and (Qmvb) control loops during recovery from the grid fault.

  • Publication number: 20200295953
    Abstract: Crossbar arrays (e.g., Resistive Processing Unit (RPU) accelerators) are leveraged to create a Physically Unclonable Function (PUF) that exploits variations, such as statistical process variation in manufacture or operation, to generate key material to secure information in a computing environment. One environment is a cloud compute infrastructure whose shared resources are used to process workloads. During RPU accelerator use, the state of the RPU's bits are changed by reproducible inputs, e.g., stochastic pulses applied to change resistive values in the array, and the corresponding changes in the RPU array state captured. These responses, which cannot be reproduced from another device due to random device variations across chips that embody the RPUs, are then used to generate (or facilitate generation of) the cryptographic material. In one embodiment, inputs applied to the RPU accelerator array are generated from a pseudo-random number generator that is otherwise associated with the RPU accelerator.
