Abstract: A computer data processing system includes an instruction pipeline having a front end and a back end, a decoding and dispatch unit to dispatch a current instruction; and a pipeline by-pass unit to invoke an out-of-order pipeline by-pass operation. The pipeline by-pass unit by-passes a section of the instruction pipeline such that the current instruction architecturally completes before initiating instruction execution. The computer data processing system further includes a post-completion execution unit that executes the current instruction after the current instruction architecturally completes.

Abstract: A display system can be configured to receive, via a user interface, a first identifier associated with a first space object and determine a first maneuver of the first space object. The first maneuver can include a perturbation of the path of the first space object. Based on the first identifier and the first maneuver, the display system can identify one or more path parameters associated with a path of the first space object and generate a display interface. The display interface can include a longitude-time graph having a longitude axis spanning from a lower-longitude limit to an upper-longitude limit and a time axis spanning from the lower-time limit to the upper-time limit and an indication of the one or more path parameters.

Abstract: A method includes allocating a first entry in a global completion table (GCT) on a processor, responsive to a first instruction group being dispatched, where the first entry corresponds to the first instruction group. A data value applicable to the first instruction group is identified. An offset value applicable to the first instruction group is calculated by subtracting, from the data value, a base value previously written to a second entry of the GCT for a second instruction group. The offset value is written in the first entry of the GCT in lieu of the data value.

Abstract: Implementing processor instrumentation in a processor pipeline includes determining a pipeline depth of each micro-operator for an instruction group used in an execution phase of the processor pipeline. The pipeline depth corresponds with a duration of execution, each micro-operator performs a type of functional operation in the execution phase, and the instruction group includes all the micro-operators required for the execution phase. A targeted micro-operator is identified for which the processor instrumentation is being performed, and the pipeline depth corresponding with the targeted micro-operator is used to determine and report a performance of the targeted micro-operator as part of the processor instrumentation. Problems indicated by the processor instrumentation are diagnosed and addressed based on the performance of the targeted micro-operator.

Abstract: A computer-implemented method for detecting vulnerabilities in microarchitectures. A non-limiting example of the computer-implemented method includes creating a simulation for execution on a model of a microarchitecture, the simulation including a set of instructions and a placeholder for holding a piece of secret data. The computer-implemented method executes the simulation a first time on the model of the microarchitecture with a first piece of secret data stored in the placeholder and stores a first output of the first executed simulation. The computer-implemented method executes the simulation a second time on the model of the microarchitecture with a second piece of secret data stored in the placeholder and stores a second output of the second executed simulation. The computer-implemented method compares the first output with the second output and provides an indication of a microarchitecture vulnerability when there is a difference between the first output and the second output.

Abstract: Systems and methods are disclosed herein for enforcing digital signature on a token useable by a network-addressable device to invoke service calls on services of a service provider. A device platform service of the service provider may receive service calls from the network-addressable device and cause one or more operations to be performed by other services of the service provider in response to receiving a notification that the request is authentic. An authentication service analyses a fingerprint associated with a request submitted by the device and determines whether it is a match to a fingerprint generated from cryptographic authentication information provided by the user in connection with registering the network-addressable device.

Abstract: An automated method for processing security events in association with a cybersecurity knowledge graph. The method begins upon receipt of information from a security system representing an offense. An initial offense context graph is built based in part on context data about the offense. The graph also activity nodes connected to a root node; at least one activity node includes an observable. The root node and its one or more activity nodes represent a context for the offense. The knowledge graph, and potentially other data sources, are then explored to further refine the initial graph to generate a refined graph that is then provided to an analyst for further review and analysis. Knowledge graph exploration involves locating the observables and their connections in the knowledge graph, determining that they are associated with known malicious entities, and then building subgraphs that are then merged into the initial graph.

Abstract: The present invention provides a pipe coupling comprising a tubular body having an open end, sealing means within the tubular body and pipe engaging means operable between a pipe clamping configuration in which an inserted pipe is clamped and a pipe release configuration in which an inserted pipe is not clamped and is releasable. A seal protector means is operable between a seal covered configuration in which the sealing means is at least partially covered and shielded from contact with an end of an inserted pipe, and a seal uncovered configuration in which the sealing means is uncovered and in contact with the inserted pipe. Moving means arranged within the tubular body is activated when a pipe is inserted a predetermined distance into the tubular body to move the seal protector means from the seal covered configuration to the seal uncovered configuration and the pipe engaging means from the pipe release configuration to the pipe clamping configuration.

Abstract: A system that implements a data storage service may store data for a database table in multiple replicated partitions on respective storage nodes. In response to a request to back up a table, the service may back up individual partitions of the table to a remote storage system independently and (in some cases) in parallel, and may update (or create) and store metadata about the table and its partitions on storage nodes of the data storage service and/or in the remote storage system. Backing up each partition may include exporting it from the database in which the table is stored, packaging and compressing the exported partition for upload, and uploading the exported, packaged, and compressed partition to the remote storage system. The remote storage system may be a key-value durable storage system in which each backed-up partition is accessible using its partition identifier as the key.
