Abstract

fetched live from OpenAlex

To more effectively use HPC clusters, co-allocating jobs across multiple clusters becomes an attractive possibility with the primary benefit being reduced turnaround time. This, ultimately, depends on the inter- cluster communication cost. In our previous research, we introduced a co-allocation strategy, MBAS, that made use of two threshold values to control allocation: one for control link saturation and another to control job splitting. In this paper, we examine the performance of MBAS. A simulation study concludes that assigning jobs with different priorities according to their communication patterns, and adjusting the threshold values for link saturation level control and chunk size control in splitting jobs, the MBAS co- allocation strategy can significantly improve both user' satisfaction (in terms of turn around time) and system resource utilization consistently, even for jobs having large communication requirements.

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.
