Coordinated Panic Flow for Hybrid OS Error Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hybrid computing environments face challenges in presenting a unified computing device image and effectively coordinating error recovery across multiple processing systems, as existing systems struggle to manage complex I/O operations and maintain cohesive error reporting in the presence of fatal errors.
Innovation Solution
Implementing a coordinated panic flow mechanism where multiple independent processors within a computing device interconnect via a transport-agnostic communication link to detect and handle errors independently, generating a combined error log and enabling unified error reporting and recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple independent processors operate independently in a hybrid computing environment, then system functionality and processing capability are improved, but error coordination and unified error reporting become more difficult
Solution Approach 1:
The patent introduces a coordination mechanism that acts as an intermediary between multiple independent processors. When a fatal error occurs on one processor, the coordination mechanism enables other processors to detect the error state and participate in error handling, allowing unified error reporting without requiring complex direct communication between all processor pairs.
2Speed
If each processor handles errors independently, then error handling speed is improved, but system-wide error recovery coherence deteriorates
Solution Approach 1:
The patent merges independent error handling operations into a coordinated system-wide error recovery process. When a fatal error is detected, the coordination mechanism combines error handling activities across multiple processors, ensuring that all processors contribute to and receive consistent error status information, thereby maintaining recovery coherence while preserving the speed benefits of parallel processing.
3Loss of information
If a unified error reporting system is implemented across multiple processors, then error reporting completeness is improved, but system complexity increases
Solution Approach 1:
The patent extracts the coordination logic from individual processor error handling routines and implements it as a separate coordination mechanism. This allows each processor to maintain simple, fast independent error detection while the extracted coordination function handles the complexity of unified error reporting, achieving complete error information collection without proportionally increasing overall system complexity.
Data Source
AI summary
One embodiment provides for a data processing system comprising multiple independent processors to execute multiple operating system environments of the data processing system, the multiple operating system environments to enable operation of multiple regions of a computing device associated with the data processing system. The multiple operating system environments are interconnected via a transport agnostic communication link. In response to detection of a fatal error in one or more of the multiple operating system environments, the multiple operating system environments coordinate performance of multiple separate error handling operations within the multiple operating system environments to generate a combined error log. The combined error log includes operational states of the multiple operating system environments.
