Abstract

fetched live from OpenAlex

The Hierarchical Computations on Manycore Architectures library (HiCMA) aims to tackle the challenge that is facing the linear algebra community due to an unprecedented level of on-chip concurrency, introduced by the manycore era. HiCMA is a high performance numerical library, which implements hierarchical numerical algorithms (e.g., matrix computations, eigenvalue decomposition, H-matrix, FMM, etc.) on emerging architectures. The hierarchy expression of the algorithms allows to enhance data locality (communication-reducing), while still ensuring embarrassingly parallel workloads (synchronization-reducing). The core idea is to redesign the numerical algorithms and to formulate them as successive calls to hierarchical computational tasks, which are then scheduled on the underlying system using a dynamic runtime system to ensure load balancing. The algorithm is then represented as a Directed Acyclic Graph (DAG), where nodes represent hierarchical tasks and edges show the data dependencies between them.

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.

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.
