Abstract

fetched live from OpenAlex

We describe the design of a lightweight library using MPI to support stream-processing on acyclic process structures. The design can be used to connect together arbitrary modules where each module can be its own parallel MPI program. We make extensive use of MPI groups and communicators to increase the flexibility of the library, and to make the library easier and safer to use. The notion of a communication context in MPI ensures that libraries do not conflict where a message from one library is mistakenly received by another. The library is not required to be part of any larger workflow environment and is compatible with existing MPI execution environments. The library is part of MarketMiner, a system for executing financial workflows.

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.

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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.
