Abstract

fetched live from OpenAlex

This paper concerns the parallelization of an in-house three-dimensional unstructured finite volume computational fluid dynamics (CFD) code (FJ3SOLV). This is part of the code development project for store release trajectory prediction at the Institute for Aerospace Research of the National Research Council Canada. The parallelization was based on the Data Decomposition method. The additive Schwarz Domain Decomposition method was used to obtain solutions in the subdomains. The domain of interest (unstructured grid) was partitioned into a number of balanced subdomains using the ParMETIS library. The message passing interface (MPI) system was used to perform parallel computation and communication between the processors. A parallel high performance aerodynamics code (HiPAC) was developed. Parallel computations of inviscid flows around a Delta wing and the CF-18 aircraft were carried out using different numbers of processors. Excellent scalability and very good quality solutions were obtained.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
