Workflows with Autosubmit in EDITO

Abstract

The European Digital Twin of the Ocean, EDITO, is an initiative of the European Commission that aims to create a virtual representation of marine and coastal environments around the globe to assess future impacts of climate change and human activities, improving the accessibility of ocean knowledge. EDITO Infra is the backbone of EDITO. It provides the infrastructure where components of the EDITO digital twin are combined and integrated. In this work, we describe how Autosubmit is integrated and used in EDITO Infra, as the back-end component of the Virtual Ocean Model Lab (VOML, a virtual co-working environment). Users of the digital twin can connect to the VOML to customize and build ocean models, run using cloud and HPC resources, and access applications deployed in the EDITO Infra that consume the output of the models. Besides usually being a local software that helps users to leverage remote resources, in this case we demonstrate Autosubmit's versatility with this scenario in which it is deployed using Docker and Kubernetes, tools used traditionally in cloud environments. In this context, Autosubmit acts as a middleware between the applications, and HPC and Cloud resources. It manages experiments and workflows, connecting EuroHPC’s like MareNostrum 5 and Leonardo. It provides integration with different GUI’s (with a REST API), GIS systems, and other services.
