About Sunflower
A full-system simulator that models multiprocessors or networks of processors, their power consumption, electrochemical batteries and voltage regulators, failures in computation and networks and analog signals in their environments.

The Sunflower simulator is part of a larger suite of free / open source hardware and software tools intended for the design and exploration of networks of resource-constrained and failure-prone systems. The suite includes hardware platforms ranging from an energy-scavenging embedded system platform, to a 24-processor embedded multiprocessor, and a handheld portable computing device. These hardware platforms may be modeled within the simulation framework, and measurements taken on the platforms may similarly be used to calibrate properties of the simulation.
