Abstract: We describe a first successful application of the LEXIS platform for advanced orchestration of complex simulation and data-analysis workflows in mixed cloud/HPC environments. A workflow for forest fire risk assessment based on the models WRF and RISICO was executed, using IaaS cloud resources at LRZ (DE) and national HPC resources at IT4I (CZ). Besides concept and results of the workflow, our contribution focuses on core systems of LEXIS: a distributed data infrastructure using iRODS and EUDAT, and an orchestration system with the novel ability to address HPC schedulers besides IaaS clouds. The approach and open platform, currently federating IT4I, LRZ and ECMWF (UK), are aimed at broad application within the current project (“Large-scale EXecution for Industry and Society”, H2020 GA 825532) and beyond.
