Vessim

Vessim is a versatile co-simulation testbed for carbon-aware applications and systems which connects domain-specific simulators for renewable power generation and energy storage with real software and hardware. It simulates energy systems that interact with real or simulated computing systems for:

• Carbon-aware applications: Microgrids simulated by Vessim offer real-time visibility and control via APIs, enabling the development and testing of novel applications that interact with their energy system.
• Energy system composition: Examine how the integration of solar panels, wind energy, or batteries would affect the energy mix of your datacenters.
• Digital Twins: Predict future system states in carbon-aware datacenters, aid decision-making, and assess risks during extreme events like power outages.
• Quality Assurance: Apply Vessim in continuous integrating testing or use it to validate software roll-outs in a controlled environment.

LEAF

LEAF is a simulator for Large Energy-Aware Fog computing environments. It enables then modeling of complex application graphs in distributed, heterogeneous, and resource-constrained infrastructures. A special emphasis was put on the modeling of energy consumption (and soon carbon emissions).

Besides allowing research on scheduling and placement algorithms on resource-constrained environments, LEAF puts a special focus on:

• Dynamic networks: Simulate mobile nodes which can join or leave the network during the simulation.
• Power consumption modeling: Model the power usage of individual compute nodes, network traffic and applications.
• Energy-aware algorithms: Implement dynamically adapting task placement strategies, routing policies, and other energy-saving mechanisms.
• Scalability: Model the execution of thousands of compute nodes and applications in magnitudes faster than real time.
