Abstract

fetched live from OpenAlex

Small-scale multiprocessors are becoming increasingly economical and common, whereas larger multiprocessors continue to have higher per-node costs. The NUMAchine multiprocessor project seeks to make large-scale multiprocessors more economical while maintaining high performance by exploring architectural and hardware features for low-cost, modular multiprocessors. To demonstrate our approach, we have implemented a prototype system that is scalable to 128 processors. An efficient directory-based cache coherence protocol exploits our hierarchical ring-based interconnect and supports sequential consistency. This paper documents the design choices and the resulting performance of the system using both simulation results and measurements on the prototype hardware.

Full frame distilled prediction

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.
