Abstract
In this paper we address the problem of distributing rendering computations for real-time display of very large 3D models using a graphics cluster. With a programmable graphics processing unit (GPU) in each node, rendering computations are increasingly carried out in two phases using two separate GPU programs: a vertex shader program for vertex (geometry) processing and a fragment shader program for pixel (color) processing. With fragment shader programs becoming more and more time consuming for increased realism and special visual effects, distributing load solely based on geometry as is done in most contemporary systems can cause significant load imbalance. There is often only a weak correlation between geometry and pixel data distribution, due to multiple factors such as occlusion of objects behind, by objects in front. Clearly, load balancing for geometry processing or pixel processing alone is not optimal. In this paper, we present a novel in-frame two-phase load-balancing technique that distributes data first for geometry and then for pixel processing. The technique is implemented on a graphics cluster and experimental results demonstrate considerable improvements in rendering performance.

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
