List-Based Task Scheduling for Cloud Computing
Bibliographic record
Abstract
Cloud computing model provides global and on-demand access to resources in a seamless manner with minimal interaction with the service provider. A typical cloud data center consists of several computational resources interconnected with each other through high-speed networks. In cloud the program execution can be visualized as a collection of multiple tasks represented by Directed Acyclic Graph (DAG) that execute in their logical sequence. Prioritization of these tasks plays an important role to achieve high performance and improved efficiency in a cloud environment. In this paper, we propose a novel task scheduling algorithm named Median Deviation based Task Scheduling (MDTS), which uses Median Absolute Deviation (MAD) of the Expected Time to Compute (ETC) of a task as a major attribute to calculate ranks of the given tasks. We use coefficient-of-variation (COV) based technique that considers task and machine heterogeneity to estimate the ETC of a particular DAG. The proposed algorithm is evaluated under various conditions using synthetic DAGs and real world applications. Our evaluation shows that the proposed MDTS algorithm produces high quality schedules and significantly reduces the makespan of an application by up to 25.01%.

Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
