Grape: Practical and Efficient Graphed Execution for Dynamic Deep Neural Networks on GPUs
Bibliographic record
Abstract
Achieving high performance in machine learning workloads is a crucial yet difficult task. To achieve high runtime performance on hardware platforms such as GPUs, graph-based executions such as CUDA graphs are often used to eliminate CPU runtime overheads by submitting jobs in the granularity of multiple kernels. However, many machine learning workloads, especially dynamic deep neural networks (DNNs) with varying-sized inputs or data-dependent control flows, face challenges when directly using CUDA graphs to achieve optimal performance. We observe that the use of graph-based executions poses three key challenges in terms of efficiency and even practicability: (1) Extra data movements when copying input values to graphs’ placeholders. (2) High GPU memory consumption due to the numerous CUDA graphs created to efficiently support dynamic-shape workloads. (3) Inability to handle data-dependent control flows.

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.
