Abstract
The increasing complexity of Distributed Computing (DC) systems necessitates advanced failure prediction techniques to ensure reliability and efficiency. However, the hierarchical architecture of DC systems presents a significant challenge in developing generic failure prediction models owing to the trade-off between prediction accuracy and cost. This study addresses this challenge by proposing a comprehensive methodology for developing and evaluating hierarchical failure prediction models in DC systems. We used the Grid5000 failure dataset to conduct an in-depth exploratory data analysis and statistical examination of the system failure characteristics, providing insights into complex failure patterns. Our approach involves developing, evaluating, and comparing ML-based models across different hierarchical levels (systems, sites, and clusters) using logistic regression, random forest, and XGBoost. These models can predict key metrics, such as time between failures (TBF), time to return/repair (TTR), and failing node identification (NFI). After intensive experiments, XGBoost demonstrated robust predictive capabilities, achieving 66-100% accuracy for TBF, TTR, and NFI across different levels in the DC system hierarchy. In addition, we introduce a hierarchical DC failure prediction architecture to enhance system reliability and cost efficiency. We also demonstrate how service providers can optimise resource utilisation and costs by tailoring service reliability through hierarchical failure prediction, leading to superior cost-effective system level predictions or highly reliable cluster level predictions.

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
