Abstract

fetched live from OpenAlex

@ita.brAbstract. We present a collection of Fortran 90 routines for the setting of unstructuredgrids on distributed systems. The routines implement methods to construct, distribute(using a third-party mesh partitioner) and set unstructured meshes of hexahedral, tetra-hedral and triangles. Among other tasks, the routines can distribute a grid, create theconnectivity table of elements and nodes, add overlapping to each sub-grid, perform basicoperations such as getting the neighbours of a given element or node, set boundary facetsand calculate element proprieties such as volume. The routines have been implemented inFortran 90 using MPI and a object-based paradigm. METIS has been used as the meshpartitioner.

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.
