摘要
Quantifying execution latency is an important consideration across Machine Learning. Existing latency-prediction approaches typically train ML models on traces collected from workload execution on target hardware. Collection of representative traces across many consumer GPUs is expensive both in organizing the devices and in manpower, causing existing work to mainly focus on a limited set of high-end GPUs available in cloud computing. To offset this cost, we show that a local host GPU can be configured to reproduce the execution performance of less powerful target GPUs. Through selectively modifying device parameters, we obtain locally measured latencies that closely approximate those observed on the target hardware. We reformulate the latency-prediction task: instead of fitting a prediction model to a dataset of execution traces, we identify local configurations that best reproduce target devices' performance, enabling zero-shot prediction. We evaluate our approach against real measurements from 60 computer-vision models executed on 21 consumer GPU models. Our method achieves a mean absolute percentage error (MAPE) of 14.21%, compared with more than 25% for comparable baselines, reducing relative prediction error by 43.6%. Predicted and measured latencies exhibit an average Spearman correlation of 0.961 across training tasks, demonstrating that the method also accurately preserves performance rankings across devices.
