Exploiting Processor Heterogeneity to Improve Throughput and Reduce Latency for Deep Neural Network Inference
Bibliographic record
Abstract
The growing popularity of Deep Neural Networks (DNNs) in a variety of domains, including computer vision, natural language processing, and predictive analytics, has led to an increase in the demand for computing resources. Graphics Processing Units (GPUs) are widely used for training and inference of DNNs. However, this exclusive use can quickly lead to saturation of GPU resources while CPU resources remain underutilized. This paper proposes a performance evaluation of a solution that exploits processor heterogeneity by combining the computational power of GPUs and CPUs. A solution is proposed for distributing the computational load across the different processors to optimize their utilization and achieve better performance. A solution for partitioning a DNN model with different computational resources is proposed. This solution transfers part of the load from the GPUs to the CPUs when necessary to reduce latency and increase throughput. The partitioning of DNN models is performed using METIS to balance the computational load to be distributed among the different resources while minimizing communication. The experimental results show that latency and throughput are improved for a number of DNN models. Potential applications include real-time processing systems such as autonomous vehicles, drones, and video surveillance systems where minimizing latency and maximizing throughput are critical.

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.
