Currently, Chaldene is not optimised for computationally intensive AI workflows. This limitation hinders its application for cutting-edge, AI-driven research within the NFDI community. To address this gap, we are working on connecting Chaldene to High-Performance Computing (HPC) infrastructures using containerised workflow execution. This approach requires a robust trust and identity framework, making the integration with the NFDI Authentication and Authorisation Infrastructure (AAI) essential for two primary functions: Secure HPC Access: The NFDI AAI is required to provide researchers with seamless and secure authenticated access to remote HPC resources. It will allow Chaldene to act on a user’s behalf, submitting containerised jobs to clusters by leveraging the user’s trusted home institution identity, thus eliminating the need for separate credentials. FAIR Workflow Sharing: To make Chaldene workflows truly shareable and reproducible according to FAIR principles, the NFDI AAI is necessary. It ensures that when a workflow is shared, a collaborator can execute it using their own verified identity, accessing the required data and compute resources they are authorized for, regardless of their institution.
Chaldene: Accessible High-Performance Computing for Image Processing is an incubator project within the Identity and Access Management (IAM) basic service of Base4NFDI.
