Abstract: Disclosed are a method and device for controlling the state switching of a fluid torque converter, a vehicle and a storage medium, the method including: obtaining a target instruction when the torque converter of the vehicle is in a locked state, the target instruction triggering a change in the torque transmission direction of a transmission system of the vehicle; obtaining a state parameter, and determining whether the current vehicle is in a target operating condition according to the state parameter; and if the current vehicle is in the target operating condition, switching the fluid torque converter to an open state, and switching the torque converter back to the locked state after maintaining the open state for a preset period of time.

Abstract: A method and system for verifying state monitor reliability in hyper-converged infrastructure (HCI) appliances. Specifically, the method and system disclosed herein entail using a supervised machine learning model—i.e., a classification decision tree—to accurately distinguish whether conflicting event notifications, logged across multiple state monitors tracking state on an HCI appliance, are directed to a real event or a non-real event. The classification decision tree, generated based at least on information gains calculated for the multiple state monitors, may reflect which state monitor(s) is/are more reliable in accurately classifying the conflicting event notifications.

Abstract: Embodiments of the present disclosure relate to a method, a device and a computer program product for service access. The method comprises receiving, from a requester, a request for accessing a first functional interface of a first service of a plurality of services. The method also comprises, in response to the request, determining a first combined permission of the requester to access a plurality of functional interfaces of the plurality of services. The method further comprises determining a second combined permission of the first service to access the plurality of functional interfaces of the plurality of services. In addition, the method comprises controlling, based on the first and the second combined permissions, access of the requester to the first functional interface. The method can accomplish rapid, safe service calling and improve service accessing efficiency.

Abstract: A Hyper-Converged Infrastructure (HCI) monitoring system includes server devices that each provide a respective HCI system that is part of an HCI cluster. A communication queue and a manager subsystem are provided on at least one of the server devices. The manager subsystem provides, in the communication queue, first workload code that is configured to run on a first server device and that is associated with a first HCI system identifier for a first HCI system provided by the first server device. The first HCI system accesses the communication queue, retrieves the first workload code in response to the first workload code being associated with the first HCI system identifier, executes the first workload code, and provides associated results to the communication queue. The manager subsystem retrieves, from the communication queue, the first results, and reports at least one of the first results to an administrator device.

Abstract: A message system includes a first node that may send a message to a second node, provide metadata associated with the message, and send the metadata to a database. The database may determine that the message was not received by the second node based upon the metadata and a current time, and direct the first node to resend the message to the second node in response to determining that the message was not received. The first node further may resend the message.
