Abstract: This thesis, suggested by Dolphin Semiconductor and the TIMA laboratory, is supervised by M. Sebastien Genevey (Dolphin Semiconductor) and M. Emmanuel Simeu (TIMA). It focuses on power management in high-performance computing processing units, especially with an integrated Adaptive Voltage Scaling (AVS) method. There are different objectives for this thesis.
First of all, it is needed to model the High Performance Computing (HPC) processor's Power Delivery Network (PDN) while taking into account physical behavior associated with high current drawn at high frequencies.
Next, it will be needed to define the inter-partition communication parameters between the different AVS systems and then, to suggest a coordination and adaptive power management algorithm.
Finally, a hardware or software prototype must be produced to corroborate the concepts.
This thesis fits in Dolphin Semiconductor's strategic plan, ahead of current work on the subject.
For TIMA, this thesis is in line with its objectives to reduce the energy consumption of systems, and more particularly for the RMS department, where the robustness and reliability of systems is one of the key objectives.
