Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Two-phase thermal hydraulics code, CUPID for multi-dimensional, multi-physics and multi-scale analysis in PWR was parallelized to fulfil the demand for long transient or high-resolved thermal hydraulics calculation. the CUPID code was parallelized based on the domain decomposition method with MPI (Message Passing Interface). For domain decomposition, the CUPID code provides both manual and automatic method with METIS library. For the effective memory management, the CSR (Compressed Sparse Row) format is adopted, which is one of the methods to represent the sparse asymmetric matrix. By performing the verification for the fundamental problem set, the parallelization of the CUPID has been successfully confirmed. In this paper, the characteristics of the parallelized CUPID code were investigated. Since the scalability of a parallel simulation is generally known to be better for fine mesh system, three types of mesh system are considered: 40,000 meshes for coarse system, 320,000 meshes for fine system. In the given geometry, both single- and two-phase calculations are conducted. In addition, two types of preconditioning for matrix solver were compared: diagonal and incomplete LU preconditioning.

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.
