Engineering Contradiction Analysis
1Productivity
If generic operating system parameters are used, then system stability is maintained, but application performance is suboptimal
Solution Approach 1:
The patent implements dynamic operating system parameter adjustment by continuously monitoring application workload characteristics and automatically modifying parameters in real-time. The system transitions from static generic parameters to dynamic workload-specific parameters, allowing the OS to adapt its behavior based on current application demands without requiring manual configuration intervention.
Solution Approach 2:
The patent systematically changes operating system parameters based on identified workload types. Different parameter sets are applied for different workload categories (e.g., CPU-intensive, memory-intensive, I/O-intensive), allowing optimization of application performance while maintaining system stability through controlled parameter transitions.
2Reliability
If workload-specific policies are generated, then service smoothness is improved, but system complexity increases
Solution Approach 1:
The patent segments the monolithic parameter adjustment process into distinct workload-type-specific policies. By dividing the parameter space into separate policies for different workload categories, the system manages complexity through modular organization while maintaining service smoothness through targeted optimizations for each segment.
Solution Approach 2:
The system implements self-service by automatically generating and applying workload-specific policies without external intervention. The OS monitors its own state, identifies workload types, selects appropriate policies, and adjusts parameters autonomously, reducing the need for complex external configuration management.
3Productivity
If manual parameter tuning is performed, then performance optimization is achieved, but time consumption increases
Solution Approach 1:
The patent enables the operating system to automatically tune its own parameters by monitoring application workloads and applying appropriate policies without human intervention. This self-service capability eliminates the time-consuming manual tuning process while maintaining performance optimization through automated workload-based parameter adjustment.
Solution Approach 2:
The system performs preliminary action by pre-defining multiple workload-type-specific policies in advance. When a workload type is identified, the corresponding pre-prepared policy is immediately applied, avoiding the need for real-time manual tuning and enabling rapid performance optimization.
