| <p>ZHANG, Zhen</p> <p>(Remote)</p> | Experiences and lessons learned from EP scientific workflow | <p>15'</p> <p>9:15-9:30</p> | An automated and efficient workflow is crucial for scientific output in astronomy, particularly in time-domain astronomy. The National Astronomical Data Centre (NADC) has undertaken the development of the workflow for the Einstein Probe(EP), a high-energy X-ray satellite focused on time-domain astronomy. During the development process, we encountered challenges including workflow orchestration, workflow scalability, and the traceability of data product generation processes. To address these issues, we developed a workflow framework based on cloud technologies, including containers, message queues, and workflow orchestrators, etc. This framework offers excellent scalability and portability and significantly enhances the efficiency of complex algorithm integration and deployment in multi-team collaborations. Finally, we proposed our recommendation for provenance and workflow data model. This framework can be further applied to future time-domain astronomy projects, and we hope that our experiences can provide insights for the IVOA workflow standards. | |
| Baptiste Cecconi | Workflow orchestration for radio interferometric imaging using EXTRACT | <p>15'</p> <p>9:30-9:45</p> | We present the result of the EXTRACT project, which is proposing a compute continuum framework (with edge, cloud and HPC compute resources) on a distributed data environment. In our presentation, we will show how we deploy multiple cloud-ready and HPC-ready technologies to furnish radio astronomers with a simple interface to describe data processing workflows which dramatically lowers the difficulty threshold of using complex tools from the radio interferometric community. In the case of NenuFAR, we propose workflows to dynamically process the imaging data of the dynamic Sun, which enables the astrometric localisation of the solar bursts (Type II, Type III bursts), and planets (e.g. Jupiter, exoplanets), complementary to beamformed observations. This workflow integrates classical LOFAR tools and methods as well as recent direction-dependent tools (e.g. DDFacet, killMS, DynSpecMS) to perform complex operations on interferometric data, such as the processing of the NLFSS sky survey and the search for exoplanetary signatures using rebuilt dynamic spectra derived from imaging data. <p>We will discuss how this will be interfaced with IVOA standards for data provenance and data discoverability.</p> | |
