Abstract
- With deep learning (DL) technology becoming an integral part of the new intelligent software, tools of DL framework testing and bug-finding are in high demand. Existing DL framework testing tools have limited coverage on bug types. For example, they lack the capability of finding performance bugs, which are critical for DL model training and inference regarding performance, economics, and the environment. This problem is challenging due to the difficulty of getting test oracles of performance bugs. Moreover, existing tools are inefficient, generating hundreds of test cases with few trigger bugs. In this paper, we propose CITADEL, a method that accelerates the finding of bugs in terms of efficiency and effectiveness. We observe that many DL framework bugs are similar due to the similarity of operators and algorithms belonging to the same family (e.g., Conv2D and Conv3D). Orthogonal to existing bug-finding tools, CITADEL aims to find new bugs that are similar to reported ones that have known test oracles. It works by first collecting existing bug reports and identifying problematic APIs. CITADEL defines context similarity to measure the similarity of DL framework API pairs and automatically generates test cases with oracles for APIs that are similar to the problematic APIs in existing bug reports. CITADEL respectively covers 1,436 PyTorch and 5,380 TensorFlow APIs and effectively detects 79 and 80 API bugs, among which 58 and 68 are new, and 36 and 58 have been confirmed, many of which, e.g., the 11 performance bugs cannot be detected by existing tools. Moreover, a remarkable 35.40% of the test cases generated by CITADEL can trigger bugs, which significantly transcends the ratios of 0.74%, 1.23%, and 3.90% exhibited by the state-of-the-art methods, DocTer, DeepREL, and TitanFuzz.<br />Comment: 12 pages, 10 figures
