FONDA – Foundations of Workflows for Large-Scale Scientific Data Analysis
DFG Collaborative Research Center 1404 at Humboldt-Universität zu Berlin
From September 10-12, FONDA’s doctoral researchers met at Coconat space for a self-organized retreat. The group shared tools they use to keep their research organized and worked on abstracts for potential collaborations between subprojects, ideas for potential master’s thesis topics, and other ideas for FONDA
We have successfully ported and contributed our Rangeland workflow [1], [2] to the nf-core workflow repository. This milestone marks the release of the first non-bioinformatics workflow on nf-core, which now serves as a blueprint for workflows in remote sensing and other domains. Being a part of the nf-core community confirms that our workflow uses best practices and ensures accessibility to researchers worldwide.
The Rangeland workflow analyzes trends in grassland changes, providing valuable insights for environmental research.
This achievement was made possible by subproject B5: Felix Kummer, Katarzyna Ewa Lewińska, Fabian Lehmann, and David Frantz.

Masoud Jami, né Gholami, of ZIB successfully defended his PhD thesis at the Institute of Computer Science, Humboldt-Universität zu Berlin on October 10, 2024. He enhanced C/R techniques by reducing overhead by more than 10% compared to state-of-the-art, and outperforms Reed-Solomon codes by combining XOR and partner checkpointing in terms of resiliency and computational overhead. His IOSIG plugin for GCC adds pragma annotations to specify I/O characteristics of certain streams, enabling injected code to choose optimal devices during runtime. His accurate I/O models of the Linux kernel that consider page caching behavior estimate I/O costs with over 80-90% accuracy.
Congratulations!
We’re excited to share that the second phase of our project has been accepted! We’re looking forward to four more years of working together with this fantastic group.
We are delighted that Humboldt-Universität decided to fund a new
Interdisciplinary Center on Greencompute – saving
energy in large-scale data analysis, led by Ulf Leser (Computer
Science) and Claudia Draxl (Physics).
The next FONDA RTG will take place the 6th of March. The PhD students will gather to improve their thesis story by presenting each others project.
Since FONDA’s research is focussed on the area of Data Analysis Workflows, we are interested in working with researchers from the community. Therefore, we are especially grateful to spotlight our ongoing collaboration with the Workflows Community Initiative. The Workflows Community Initiative (WCI) is a community-centered effort for gathering and promoting long-standing and recent community-focused efforts. Learn More about WCI here.
We congratulate our Partners of the Earth Observation Lab HU for winning the Open Access Award of HU Berlin. We are thankful that their good research is also helping FONDA to move forward!
FONDA got together for the last retreat in 2023. We met in Wandlitz from November 9 to November 10.
We are happy to share that FONDA is a partner of METIS. METIS is a freely available website project providing advice on how to promote gender equality, family friendliness, diversity, and anti-discrimination in research alliances at Humboldt-Universität zu Berlin and at Charité.
