DescriptionAutomating the workload characterization process is increasingly important in hardware design. Although compiler tools can automatically collect profiling data and predict performance behaviors, the process has to be repeated for each potential design. Such challenge is exacerbated by the fast growing body of applications and input problems.

We propose an alternative approach based on code similarity learning. The application is decomposed into small kernels that can be mapped to known patterns. The behaviors of a pattern on a hardware setup can be reused. To enable this technology, we propose a new code representation and similarity metric. We automate the detection process using compiler and ML methods. Specifically, we reformulate application's dataflow graphs so that they can be compared based on both compute and data movement. We show this representation can distinguish kernels in the HPCG benchmark and help suggest optimal configurations for SpMV and GEMM hardware accelerators.
