Workflow Simulation Using Provenance Data Similarity and Sequence Alignment

摘要

Techniques are provided for workflow simulation using provenance data similarity and sequence alignment. An exemplary method comprises: obtaining a state of workflow executions of concurrent workflows with multiple resource allocation configurations, wherein the state comprises provenance data of the concurrent workflows; obtaining execution traces of the concurrent workflows representing different resource allocation configurations; identifying a set of states in a first execution trace and a set of states in a second execution trace as corresponding anchor states; mapping a first intermediate state to a second intermediate state between a pair of anchor states using the provenance data; generating a simulation model of the workflow executions representing the different configurations of the resource allocation; and generating new simulation traces of the workflow executions with resource allocation configurations that are not represented in the provenance data.
