Patent number: 11599432Abstract: Distributed application orchestration management is provided. A first passive member of a set of passive members sends a notification message to other members indicating that the first passive member is initiating start of a distributed application in response to the first passive member validating that a self-restart by a leader member failed. The first passive member compares timestamps associated with an attempt to start the distributed application by other passive members in the set of passive members. The first passive member stops a particular attempt to start the distributed application in response to the first passive member determining that a timestamp associated with the particular attempt to start the distributed application by the first passive member is newer than another timestamp of another passive member. The first passive member designates the other passive member having an older timestamp as a new leader member to continue starting the distributed application.Type: GrantFiled: August 12, 2021Date of Patent: March 7, 2023Assignee: Kyndryl, Inc.Inventors: Cesar Augusto Rodriguez Bravo, David Alonso Campos Batista, Ruben Luengas De La Fuente, Mauro Marzorati

Patent number: 11599429Abstract: A quantum failsafe service (QFS) is disclosed herein. In one example, a first quantum computing device executes a QFS that receives a system stress indicator from a system monitor that tracks a status of the first quantum computing device and/or a status of qubits maintained by the first quantum computing device. The QFS determines, based on the system stress indicator, that a quantum service backup is to be performed for a quantum service running on the first quantum computing device, and obtains a profile snapshot representing a current state of the quantum service. The QFS service then performs superdense encoding of the profile snapshot using a first set of qubits entangled with a second set of qubits of a second quantum computing device, and the first set of qubits are sent to the second quantum computing device (e.g., for storage in a classical data repository, according to some examples).Type: GrantFiled: March 29, 2021Date of Patent: March 7, 2023Assignee: Red Hat, Inc.Inventors: Stephen Coady, Leigh Griffin

Patent number: 11544133Abstract: A system and method for dynamic log management of stream processing in a distributed computing environment, such as, for example, a streaming application or stream analytics system. A streaming application can be deployed or published to a cluster, to execute as a client application. A cluster manager coordinates with worker nodes, to commit tasks associated with the streaming application. If a need arises to generate lower-level log data associated with the streaming application, for example to diagnose an underlying cause of a warning/error message, a configuration job can be committed to the cluster to execute as a separate log-configuration application. The log-configuration application operates with the cluster manager to determine the set of working nodes currently associated with the streaming application, and modify the logger configuration at those nodes, to record or otherwise provide log data according to a modified logging level, for example to provide lower-level log messages.Type: GrantFiled: May 10, 2019Date of Patent: January 3, 2023Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Santosh Kumar, Yathish Gatty, Devendra Jain

Patent number: 11520648Abstract: Implementing a firmware watchdog timer. A system presents a data structure over a bus which exposes, to software executing at a central processing unit (CPU), a hardware resource that is associated with a watchdog timer, attribute(s) of the watchdog timer, and (iii) commands available to the software executing at the CPU for managing the watchdog timer via one or more native CPU instructions that target the hardware resource. The system listens on the bus for a data value written to the hardware resource (i.e., by a native CPU operation issued by the software executing at the CPU), and identifies a particular command for managing the watchdog timer based on the data value written. Based on identifying the particular command, the system performs at least one of: initializing the watchdog timer, starting the watchdog timer, resetting the watchdog timer, or stopping the watchdog timer.Type: GrantFiled: September 25, 2020Date of Patent: December 6, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Bruce John Sherwin, Jr., Neeraj Ladkani, Jason Stewart Wohlgemuth, James Anthony Schwartz, Jr.
