Pangeo (pangeo.io) represents a global, open-source community of researchers and developers collaborating to tackle big data challenges in geoscience. By leveraging a range of tools—from laptops to HPC and cloud infrastructure—the Pangeo ecosystem empowers researchers with an array of core packages, including Xarray, Dask, Jupyter, Zarr, Kerchunk, and Intake.
This session focuses on use cases involving both Cloud and HPC computing and showcasing applications of Pangeo’s core packages. The goal is to assess the current landscape and outline the steps needed to facilitate the broader adoption of cloud computing in Earth Observation and Earth Modeling data processing. We invite contributions that explore various cloud computing initiatives within these domains, including but not limited to:
This session aims to:
• Assess the current landscape and outline the steps needed to facilitate the broader adoption of cloud computing in Earth Observation and Earth Modeling data processing.
• Inspire researchers using or contributing to the Pangeo ecosystem to share their insights with the broader geoscience community and showcasenew applications of Pangeo tools addressing computational and data-intensive challenges.
We warmly welcome contributions that explore:
• Cloud Computing Initiatives: Federations, scalability, interoperability, multi-provenance data, security, privacy, and sustainable computing.
• Cloud Applications and Platforms: Development and deployment of IaaS, PaaS, SaaS, and XaaS solutions.
• Cloud-Native AI/ML Frameworks: Tools designed for AI/ML applications in EO and ESM.
• Operational Systems and Workflows: Cloud-based operational systems, data lakes, and storage solutions.
• HPC and Cloud Integration: Converging workloads to leverage the strengths of both computational paradigms.
In addition, we invite presentations showcasing applications of Pangeo’s core packages in:
• Atmosphere, Ocean, and Land Modeling
• Satellite Observations
• Machine Learning
• Cross-Domain Geoscience Challenges
This session emphasizes real-world use cases at the intersection of cloud and HPC computing. By sharing interactive workflows, reproducible research practices, and live executable notebooks, contributors can help map the current landscape and outline actionable pathways toward broader adoption of these transformative technologies in geoscience.
Orals: Fri, 2 May | Room -2.32
The oral presentations are given in a hybrid format supported by a Zoom meeting featuring on-site and virtual presentations. The button to access the Zoom meeting appears just before the time block starts.
