A Simple Model for Portable and Fast Prediction of Execution Time and Power Consumption of GPU Kernels
share
Characterizing compute kernel execution behavior on GPUs for efficient task scheduling is a non-trivial task. We address this with a simple model enabling portable and fast predictions among different GPUs using only hardware-independent features. This model is built based on random forests using 189 individual compute kernels from benchmarks such as Parboil, Rodinia, Polybench-GPU and SHOC. Evaluation of the model performance using cross-validation yields a median Mean Average Percentage Error (MAPE) of 8.86-52.00 different GPUs, while latency for a single prediction varies between 15 and 108 milliseconds.
