Real-World Benchmark Results: Gaussian Elimination
In real-world benchmarks, the proposed method demonstrates significant efficiency gains. For instance, in Gaussian Elimination tasks on an NVIDIA RTX 3060 (M=30) with C_avg=20, our approach reduced the measured execution time to an average of 40.74ms, compared to 44.82ms with existing methods. This represents a substantial improvement in actual operational speed, particularly for tasks composed of numerous lightweight kernels. The method consistently yields lower standard deviation, indicating more stable and predictable performance.
