📄 Exploring the Potential of Carbon-Aware Execution for Scientific Workflows

Kathleen West, Fabian Lehmann, Vasilis Bountris, Ulf Leser, Yehia Elkhatib, and Lauritz Thamsen

To appear in the Proceedings of the 25th IEEE International Symposium on Cluster, Cloud and Internet Computing (CCGrid), 2025

In this short paper, we demonstrate the potential for carbon-aware workflow execution. For this, we estimate the carbon footprint of two real-world Nextflow workflows executed on cluster infrastructure and evaluate the impact of carbon-aware temporal shifting, pausing and resuming, and resource scaling.

💻 Ichnos: A Carbon Footprint Estimator for Scientific Workflows

Kathleen West, Yehia Elkhatib, and Lauritz Thamsen

A project with scripts to methodically calculate the carbon footprint of workflow executions from Nextflow trace files, using power models and carbon intensity data.
