Abstract
Summary In this work we present performance results of multicore wavefront diamond tiling blocking (MWD-TB) RTM and its superiority to the traditional spatial blocking-based RTM. MWD-TB RTM provides 2X speedup, while the use of MWD-TB technique in forward modeling provides 4X speedup. For future work, we plan to deploy our MWD approach for the first-order acoustic wave equation into the full RTM and FWI pipelines using the latest Intel / AMD x86 architectures and GPU hardware accelerators. Please refer to the recent publication on this research [ 4 ] for the wavefield modeling problem results on different architectures

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
