Abstract: A backpropagation enabled model is trained for estimating time-lapse property changes of a subsurface volume. Synthetic models of the subsurface volume are generated, with pre-determined property changes before and after a time lapse. These models are used to compute baseline-monitor pairs of synthetic seismic traces before and after the time lapse, wherein the baseline synthetic traces are computed from the synthetic model before the time lapse and the monitor synthetic traces are computed from the synthetic model after the time lapse. A ground truth 4D attribute characterizing the time-lapse property changes in the synthetic models is defined, and a backpropagation enabled model is trained by feeding the baseline-monitor pairs of synthetic seismic traces and the corresponding ground truth 4D attribute. The thus obtained trained backpropagation enabled model can be used to estimate time-lapse property changes of the actual subsurface Earth volume from actual baseline-monitor pairs of seismic traces.

Abstract: Systems, apparatuses, and methods for generating a measurement of write memory bandwidth are disclosed. A control unit monitors writes to a cache hierarchy. If a write to a cache line is a first time that the cache line is being modified since entering the cache hierarchy, then the control unit increments a write memory bandwidth counter. Otherwise, if the write is to a cache line that has already been modified since entering the cache hierarchy, then the write memory bandwidth counter is not incremented. The first write to a cache line is a proxy for write memory bandwidth since this will eventually cause a write to memory. The control unit uses the value of the write memory bandwidth counter to generate a measurement of the write memory bandwidth. Also, the control unit can maintain multiple counters for different thread classes to calculate the write memory bandwidth per thread class.

Abstract: A segmentation server generates vulnerability exposure scores associated with workloads operating in a segmented computing environment. The segmentation server may automatically aggregate the vulnerability exposure scores in various ways to generate vulnerability exposure information representative of workloads in an administrative domain controlled by the segmentation server. The aggregated vulnerability exposure information may be presented in a manner that enables an administrator to easily evaluate different segmentation strategies and assess the risks associated with each of them. Moreover, the segmentation server can automatically generate a segmentation policy that modifies a configured segmentation strategy based on the vulnerability exposure scores to reduce exposure to certain vulnerabilities without impeding operation of the workloads.

Abstract: A secure private network connectivity system (SNCS) within a cloud service provider infrastructure (CSPI) is described that provides secure private network connectivity between external resources residing in a customer's on-premise environment and the customer's resources residing in the cloud. Secure access to an external resource is enabled by the SNCS by creating an external resource representation (i.e., a computing instance) for the external resource in the customer's virtual cloud network (VCN) in the cloud and creating a virtual network interface card for the external resource representation. Using the SNCS, the customer can securely access the external resource residing in their on-premise network from within their VCN by connecting to the virtual IP address assigned to the VNIC without requiring to set up elaborate site-to-site networking, without making changes to their on-premise routing configuration or without making any changes to the configuration of the external resource.

Abstract: A secure private network connectivity system (SNCS) within a cloud service provider infrastructure (CSPI) is described that provides secure private network connectivity between external resources residing in a customer's on-premise environment and the customer's resources residing in the cloud. The SNCS provides secure private bi-directional network connectivity between external resources residing in a customer's external site representation and resources and services residing in the customer's VCN in the cloud without a user (e.g., an administrator) of the enterprise having to explicitly configure the external resources, advertise routes or set up site-to-site network connectivity.

Abstract: Techniques are described for generating a composite display of multiple user interface elements, each of which presents datasets corresponding to the operational parameters of computing resources even though the computer resources may operate in different computing environments. In some cases, the composite display includes a feature that enables a comparison of operational performance data between a target measurement period relative to a selectable reference period. The reference period may be manually selectable from a menu of candidate time periods or identified and/or selected by the system based on a similarity between data characteristics in the target measurement period and a baseline measurement period.

Abstract: A downhole shunt tube isolation system includes an isolation sleeve housing defining an isolation sleeve chamber and an isolation sleeve moveable within the isolation sleeve chamber between an open position and a closed position. The isolation sleeve has a slurry pathway that fluidically couples a first slurry tube segment to a second slurry tube segment with the isolation sleeve in the open position and fluidically decouples the first slurry tube segment from the second slurry tube segment in the closed position. The downhole shunt tube isolation system further includes a fluid channel in communication with the isolation sleeve chamber. The channel is initially closed to hydraulically lock the isolation sleeve in the open position. Additionally, the downhole shunt tube isolation system includes an actuation mechanism configured to open the fluid channel to hydraulically unlock the isolation sleeve and a biasing member to bias the isolation sleeve to the closed position.

Abstract: A gas-lift valve in a wellbore may include a valve housing and a flow restrictor. The valve housing may at least in part define a chamber for receiving an actuation fluid. The flow restrictor may have a position that is controllable by adjusting a downhole pressure to change a density of the actuation fluid in the chamber. The gas-lift valve may be positioned on production tubing in an annulus of a wellbore. Controlling the position of the flow restrictor may restrict an opening in the production tubing through which gas may flow.
