Micro-level Modularity of Computaion-intensive Programs in Big Data Platforms: A Case Study with Image Data
Bibliographic record
Abstract
With the rapid advancement of Big Data platforms such as Hadoop, Spark, and Dataflow, many tools are being developed that are intended to provide end users with an interactive environment for large-scale data analysis (e.g., IQmulus). However, there are challenges using these platforms. For example, developers find it difficult to use these platforms when developing interactive and reusable data analytic tools. One approach to better support interactivity and reusability is the use of microlevel modularisation for computation-intensive tasks, which splits data operations into independent, composable modules. However, modularizing data and computation-intensive tasks into independent components differs from traditional programming, e.g., when accessing large scale data, controlling data-flow among components, and structuring computation logic. In this paper, we present a case study on modularizing real world computationintensive tasks that investigates the impact of modularization on processing large scale image data. To that end, we synthesize image data-processing patterns and propose a unified modular model for the effective implementation of computation-intensive tasks on data-parallel frameworks considering reproducibility, reusability, and customization. We present various insights of using the modularity model based on our experimental results from running image processing tasks on Spark and Hadoop clusters.

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; both teacher heads agree on what is shown here.
