Metascheduling Multiple Resource Types using the MMKP
Bibliographic record
Abstract
Grid computing involves the transparent sharing of computational resources of many types by users across large geographic distances. The altruistic nature of many current grid resource contributions does not encourage efficient usage of resources. As grid projects mature, increased resource demands coupled with increased economic interests will introduce a requirement for a metascheduler that improves resource utilization, allows administrators to define allocation policies, and provides an overall quality of service to the grid users. In this work we present one such metascheduling framework, based on the multichoice multidimensional knapsack problem (MMKP). This strategy maximizes overall grid utility by selecting desirable options of each task subject to constraints of multiple resource types. We present the framework for the MMKP metascheduler and discuss a selection of allocation policies and their associated utility functions. The MMKP metascheduler and allocation policies are demonstrated using a grid of processor, storage, and network resources. In particular, a data transfer time metric is incorporated into the utility function in order to prefer task options with the lowest data transfer times. The resulting schedules are shown to be consistent with the defined policies

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
