Cucumber: Renewable-Aware Admission Control for Delay-Tolerant Cloud and Edge Workloads
Sustainable Federated Learning
Federated Learning is expected to further increase the power consumption of machine learning, which is already recognized as one of the most energy-intensive computational applications today. However, due to its distributed nature, Federated Learning also offers new opportunities to align this demand with the availability of green energy.

Flexible adjustment of computing workloads could improve carbon footprint of data centers
To reduce their carbon footprint, more and more computing systems are connected to microgrids to gain direct access to renewable energy sources. However, the local availability of solar and wind energy is highly variable and requires consumers to timely adapt their consumption to the current supply. Researchers from the Berlin Institute for the Foundation of Learning and Data (BIFOLD) have developed a new admission control approach that accepts flexible workloads such as machine learning training jobs only if they can be computed relying solely on renewable excess energy.
Scheduling computing tasks can reduce emission
To reduce the carbon footprint of cloud computing, researchers from the Berlin Institute for the Foundation of Learning and Data (BIFOLD) investigated the potential of shifting delay-tolerant compute workloads, such as batch processing and machine learning jobs, to times where energy can be expected to be green. Their publication “Let’s Wait Awhile: How Temporal Workload Shifting Can Reduce Carbon Emissions in the Cloud,” was now accepted at Middleware’21.
TUB distributed and operating systems researchers will offer multiple presentations at IEEE Big Data 2020
Three papers by researchers of the Distributed and Operating Systems group at TU Berlin, led by BIFOLD Principal Investigator Prof. Dr. Odej Kao, have been accepted for presentation at the 2020 IEEE International Conference on Big Data (Big Data 2020) and related workshops. The Conference will take place from December 10 – 13, 2020.
