Data Pipes: Declarative Control over Data Movement
Bibliographic record
Abstract
Today’s storage landscape offers a deep and heterogeneous stack of technologies that promises to meet even the most demanding data-intensive workload needs. The diversity of technologies, however, presents a challenge. Parts of it are not controlled directly by the application, e.g., the cache layers, and the parts that are controlled, often require the programmer to deal with very different transfer mechanisms, such as disk and network APIs. Combining these<br/>different abstractions properly require great skill, and even so, expert-written programs can lead to sub-optimal utilization of the storage stack and present performance unpredictability.<br/>In this paper, we propose to combat these issues with a new programming abstraction called Data Pipes. Data pipes offer a new API that can express data transfers uniformly, irrespective of the source and destination data placements. By doing so, they can orchestrate how data moves over the different layers of the storage stack explicitly and fluidly. We suggest a preliminary implementation of Data Pipes that relies mainly on existing hardware primitives to implement data movements. We evaluate this implementation experimentally and comment on how a full version of Data Pipes could be brought to fruition.

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.
