Abstract

fetched live from OpenAlex

The main challenge in the field of Very Large Instruction Word (VLIW) and superscalar architectures is ezploiting as much instruction-level parallelism as possible. In this paper an ezecution model which uses multiple instruction sequences and eztracts instruction-level parallelism at runtime from a set of enabled threads has been presented. A new multi-ring architecture has been proposed to support the ezeculion model. The multithreaded architecture features (i) large resident activations to improve program and data locality, (ii) a novel high-speed buger organization which ensures zero load/store stalls for the local variables of an activation, and (iii) a dynamic instruction scheduler that groups operations from multiple threads for ezecution. Initial performance evaluation studies predict that the proposed architecture is capable of ezecuting 7 concurrent operations per cycle with 8 ezecution pipes and 6 rings.

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.
