Solution Overview
Problem
Current methods for switching between single-threading and hyper-threading modes in computer systems require system restarts, making them cumbersome and time-consuming.
Innovation Solution
A method to dynamically switch between single-threading and hyper-threading modes under direct operating system control without the need for restarts, allowing each computing core to process either one or multiple threads based on the operating system's configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BIOS configuration is modified to switch between single-threading and hyper-threading modes, then the system can execute programs optimized for different modes, but system restart is required which causes time loss and operational inconvenience
Solution Approach 1:
The patent implements dynamic switching between single-threading and hyper-threading modes through operating system-level control mechanisms. The kernel can dynamically adjust the number of threads per CPU core based on program requirements without requiring system restart, making the threading mode flexible and adaptable during runtime
Solution Approach 2:
The invention changes the threading mode parameter dynamically by modifying kernel data structures that control thread-to-core mapping. By altering parameters such as the number of threads per core and updating scheduler configurations, the system transitions between threading modes without reboot, avoiding time loss
2Adaptability or versatility
If BIOS configuration is modified to switch between single-threading andhyper-threading modes, then the system can execute programs optimized for different modes, but the configuration process becomes cumbersome and complex
Solution Approach 1:
The patent introduces an operating system-level intermediary layer that mediates between user programs and hardware threading capabilities. This intermediary provides simplified interfaces and automatic detection mechanisms, eliminating the need for users to manually configure complex BIOS settings while maintaining adaptability to different program requirements
Solution Approach 2:
The system implements self-service capabilities through automatic detection of program threading requirements and autonomous configuration of threading modes. The kernel monitors program characteristics and automatically adjusts threading parameters without user intervention, making the system both adaptable and easy to operate
3Productivity
If hyper-threading mode is enabled to improve program execution efficiency, then programs optimized for hyper-threading can run faster, but programs optimized for single-threading experience degraded performance
Solution Approach 1:
The patent implements dynamic adaptation where the system continuously monitors program execution characteristics and adjusts threading mode in real-time. Programs optimized forhyper-threading receive multi-threaded core configurations for improved productivity, while programs optimized for single-threading automatically receive single-threaded configurations to maintain their performance, achieving both efficiency and compatibility
