Anomaly Detection in Scientific Workflows using End-to-End Execution Gantt Charts and Convolutional Neural Networks

ABSTRACT Fundamental progress towards reliable modern science depends on accurate anomaly detection during application execution. In this paper, we suggest a novel approach to tackle this problem by applying Convolutional Neural Network (CNN) classification methods to high-resolution visualizations that capture the end-to-end workflow execution timeline. Subtle differences in the timeline reveal information about the performance of the application and infrastructure’s components. We collect 1000 traces of a scientific workflow’s executions. We explore and evaluate the performance of CNNs trained from scratch and pre-trained on ImageNet [7]. Our initial results are promising with over 90% accuracy.
