Abstract

fetched live from OpenAlex

Many factors affect the performance of parallel programs including idle time, wait time, and communication costs. The latter often constitute a significant source of overhead. We consider in this paper the impact of such costs on the performance of parallel implementations of three domain decompositions of a three-dimensional model for tissue growth on a cluster. These are regular domain decompositions that comprise a slab decomposition, a rod decomposition, and a block decomposition. Using a set of measures that qualify each decomposition, we explore their capability to predict the parallel performance of each implementation. The results of our experiments confirm the applicability of using these measures as predictors of performance for our application, and potentially for other similar ones.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
