Coordinated Panic Flow for Hybrid Computing 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 individual processors may operate independently and lack cohesive error handling mechanisms.
Innovation Solution
Implementing a coordinated panic flow system where multiple processors within a hybrid computing device communicate via a transport-agnostic link to detect and report fatal errors, enabling each processor to perform error handling operations and generate a combined error log, allowing the system to recover and report unified error status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent processors operate independently in a hybrid computing environment, then each processor can function autonomously with its own operating system, but the system lacks cohesive error handling and cannot present a unified computing device image
Solution Approach 1:
The patent introduces a panic message intermediary that travels between processors through a communication link. When one processor detects a fatal error, it sends a panic message to other processors, which then coordinate their error handling operations. This intermediary mechanism enables cohesive error handling across independent processors while maintaining their operational autonomy.
2Productivity
If each processor performs separate error handling operations independently, then error recovery can be processed by individual systems, but the error reporting remains fragmented without unified coordination
Solution Approach 1:
The patent merges separate error handling operations into a coordinated system. When a panic message is received, multiple processors simultaneously perform error handling operations and log errors to a shared memory location. This combining approach preserves productive parallel error recovery while consolidating error information into a unified report that prevents information loss.
3Speed
If processors communicate via protocol-specific links, then communication can be optimized for specific transports, but the system lacks transport agnosticism and flexibility
Solution Approach 1:
The patent implements a universal communication approach where the panic message format and communication mechanism are designed to work across multiple transport protocols. The system can send panic messages through various links (PCIe, USB, serial, etc.) without protocol-specific modifications, achieving transport agnosticism while maintaining communication efficiency through standardized message structures.
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.
