Abstract
Multithreaded architectures provide an opportunity for efficiently executing programs with irregular parallelism and/or irregular locality. This paper presents a strategy that makes use of the multithreaded execution model without exposing multithreading to the programmer. Our approach is to design simple extensions to C, and to provide compiler support that automatically translates high-level C programs into lower-level threaded programs. In this paper we introduce EARTH-C, our extended C language which contains simple constructs for specifying control parallelism and data locality. Based on EARTH-C, we describe compiler techniques that are used for translating to lower-level Threaded-C programs for the EARTH multithreaded architecture. We demonstrate our approach with six benchmark programs. We show that even naive EARTH-C programs can lead to reasonable performance, and that more advanced EARTH-C programs can give performance very close to hand-coded threaded-C programs.

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
