PRoof: A Comprehensive Hierarchical Profiling Framework for Deep Neural Networks with Roofline Analysis

This is the authors' abstract. We don't add key points for this paper.

The increasing diversity of deep neural network (DNN) models and hardware platforms necessitates effective model profiling for high-performance inference deployment. Current DNN profiling tools suffer from either limited optimization insights due to the missing correlation between high-level DNN layer design and low-level hardware performance metrics, or prohibitive profiling overhead due to the large amount of performance measurement through hardware performance counters. Meanwhile, the roofline model has been widely used in the high-performance computing (HPC) domain for identifying performance bottlenecks and guiding optimizations. However, it lacks hierarchical (e.g., kernel/operator/layer), fine-grained, multi-platform support for profiling DNN models.
