How It Works

Calculate theoretical speedup from SIMD (Single Instruction Multiple Data) vectorization. Speedup = SIMD_width / scalar_width. AVX-512 processes 16 floats simultaneously vs 1 in scalar code

Each component has a specific meaning:

  • SIMD vectorization — The simd vectorization recorded for the scenario being assessed.

Note: Interpret the simd speedup result against the thresholds and context described above.

How to Use

Enter the SIMD vectorization for the scenario you are assessing. Calculate theoretical speedup from SIMD (Single Instruction Multiple Data) vectorization. Speedup = SIMD_width / scalar_width. AVX-512 processes 16 floats simultaneously vs 1 in scalar code. Use the simd speedup result to inform your calculation.
