This invention discloses a code defect analysis and repair method and system based on a large language model. The method includes: receiving crash information triggered by fuzzing or program execution, and performing crash analysis to obtain crash analysis results; obtaining key defect analysis information based on the crash analysis results, and constructing structured defect analysis information based on the key defect analysis information; inputting the structured defect analysis information into a defect analysis model, and performing reasoning analysis on the code defects according to a three-round reasoning strategy to obtain defect analysis results; searching a historical repair database based on the defect analysis results to obtain historical repair retrieval results, and inputting the defect analysis results and historical repair retrieval results into a patch generation model to generate candidate patch code; performing sandbox verification on the candidate patch code to obtain valid patch code and patch verification results, and outputting an analysis and repair report based on the defect analysis results, valid patch code, and patch verification results.

Methods and systems for detecting vehicle crash events using real-time sensor data are disclosed. In some embodiments, an application executing on a computing device disposed in a vehicle receives a stream of time-series data from one or more motion sensors during a drive. For each contiguous interval of a first predefined length, the application generates a crash prediction indicative of whether a crash occurred during that interval. Generating the crash prediction includes executing a crash detection neural network on sensor data collected over a time period that comprises the interval and has a second, greater predefined length. For each crash prediction, the application determines whether the prediction meets one or more predefined threshold criteria. In response to meeting the criteria, the application generates a crash analysis using the corresponding sensor data.

Systems and methods are disclosed for processor crash analysis using register sampling. For example, an integrated circuit may include a processor core configured to execute instructions, wherein the processor core includes a program counter register and an exception program counter register (e.g., a machine exception program counter register) that is configured to store a program counter value that was current when an exception occurred; a data store connected to the exception program counter register via an ingress port that is configured to store a copy of an exception program counter value responsive to retirement of an instruction; and an exception program counter capture register, configured to store an exception program counter value from the second data store responsive to a reset signal for the processor core.

A system is described including one or more processing resources and a non-transitory computer-readable medium, coupled to the processing resource, having stored therein instructions that when executed by the one or more processing resources cause the one or more processing resources to establish a remote direct memory access (RDMA) connection with a client computer system and remotely access a crash dump file stored at the client computer system, including providing a file offset of interest and size of data to be read from the client computer system and translating the file offset of interest and size of data into a plurality of RDMA messages.

An apparatus comprises at least one processing device configured to monitor for designated system crash event types and, responsive to detecting at least one designated system crash event type on a first information technology (IT) asset, to copy system crash log files from the first IT asset and to process the copied system crash log files to generate a first crash dump analysis data structure associated with the first IT asset. The at least one processing device is further configured to generate, based at least in part on the first crash dump analysis data structure and additional crash dump analysis data structures associated with additional IT assets, a system crash root cause analysis data structure. The at least one processing device is further configured to apply remedial actions, selected based at least in part on the system crash root cause analysis data structure, to a plurality of IT assets.

The embodiment of the invention provides an application crash alarm method and device, equipment, a storage medium and a program product. The method comprises the following steps: acquiring crash data generated by a target application in a running process in a current alarm time window; according to the crash data, determining crash information and application knowledge of the target application; wherein the crash information comprises crash stack information; generating a crash analysis result of the target application according to the crash data, the crash information and the application knowledge; wherein the crash analysis result comprises a crash repair scheme; and performing alarm pushing processing according to the collapse analysis result. The method can improve the response speed and analysis efficiency of the application crash problem.

A system is described including one or more processing resources and a non-transitory computer-readable medium, coupled to the processing resource, having stored therein instructions that when executed by the one or more processing resources cause the one or more processing resources to receive a request from a remote computer system to initiate a remote direct memory access (RDMA) connection, establish the RDMA connection with the remote computer system and provide access to a crash dump file via the RDMA connection.
