    In recent years deep neural networks (DNNs) have emerged as an important application domain driving the requirements for future systems. As DNNs get more sophisticated, their compute requirements and the datasets they are trained on continue to grow at a fast rate. For example, Gholami showed that compute in Transformer networks grew 750X over 2 years, while other work projects DNN compute and memory requirements to grow by 1.5X per year. Given their growing requirements and importance, heterogeneous systems often add machine learning (ML) specific features (e.g., TensorCores) to improve their efficiency. However, given ML’s voracious rate of growth and size, there is a growing challenge in performing early-system exploration based on sound simulation methodology. In this work we discuss our efforts to enhance gem5’s support to make these workloads practical to run while retaining accuracy.
