Engineering Contradiction Analysis
1Speed
If hardware optimizations are applied to speed up code execution, then execution speed improves, but execution anomalies and unpredictability increase
Solution Approach 1:
The system performs preliminary profiling of program code to identify performance issues and execution anomalies before actual execution. By collecting hardware-dependent metrics and analyzing execution characteristics in advance, the system prepares optimization strategies that account for potential anomalies, thereby maintaining both speed improvements and execution predictability.
Solution Approach 2:
The system implements a feedback mechanism where execution characteristics are measured during runtime, and this information is used to dynamically adjust execution strategies. The profiler collects metrics about actual execution behavior and feeds this back to modify code generation or execution parameters, ensuring that optimizations maintain predictable performance while achieving speed improvements.
2Productivity
If code is optimized for one hardware system, then performance on that system improves, but performance on new hardware systems becomes unpredictable
Solution Approach 1:
The system changes the parameters used for optimization from hardware-specific characteristics to hardware-independent execution characteristics. By profiling the actual runtime behavior of code and using these behavioral parameters for optimization instead of static hardware parameters, the optimized code maintains high performance across different hardware platforms while adapting to their specific characteristics.
Solution Approach 2:
The profiling and optimization system creates a universal approach that works across multiple hardware platforms. The system generates optimized code that is not tied to specific hardware features but rather to the execution characteristics observed during profiling, making the optimized code adaptable and efficient on various hardware systems including new architectures.
3Speed
If hardware-dependent optimization techniques are used, then execution speed improves, but portability and adaptability to new hardware decrease
Solution Approach 1:
The system replaces mechanical hardware-dependent optimization techniques with a software-based profiling and analysis approach. Instead of relying on hardware-specific instructions or architecture-dependent optimizations, the system uses software profilers to measure execution characteristics and generates optimized code based on these measurements, achieving speed improvements without sacrificing hardware independence.
