Abstract
In this paper, we have examined the performance of the elliptic solvers in the context of atmospheric modelling with a limited area grid. By using only the MPI paradigm (see Table.3) we can see that by increasing the grid size relative to the increase of the number of processors (in order that each processor keeps same amount of work), the number of iterations needed for the iterative solver to converge remains constant. We can say that the block-Jacobi preconditioner used in GEM-LAM is robust even though it involves no interprocessor communications and it is based on a single level additive Schwarz. We can also

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
