About Vessim

Most research on energy-aware and carbon-aware computing relies on simulations, as globally distributed hardware testbeds are rare and costly. Vessim addresses this gap by simplifying and unifying simulation-based evaluations and enabling continuous testing of emerging applications.

Vessim is developed by Philipp Wiesner at the Distributed and Operating Systems (DOS) group at TU Berlin. Active development for Vessim began in March 2023 with initial funding from the German Federal Ministry of Education and Research (BMBF) as part of the Software Campus project SYNERGY. We thank everyone who has contributed to Vessim over the past years, especially Marvin Steinke, Paul Kilian, and Amanda Malkowski.

Roadmap

We are currently working on the following aspects and features:

• Datasets: We are working on better integrating exiting data sources like electricity prices, carbon intensity data, or weather forecasts into Vessim.
• System Advisor Model (SAM): We are working on integrating NREL's SAM as a subsystem in Vessim, allowing for better simulation of solar arrays, wind farms, and other types of renewable energy generators.
• Battery degradation: We are working on integrating NREL's BLAST-Lite for modeling battery lifetime and degradation
• Improved modeling: We are working on more sophisticated modeling of e.g. demand response signals, time-varying PUE, ...
• Calibration: We are working on a methodology for calibrating Vessim simulations on real hardware testbeds.
