The HPC PowerStack: A Community-Driven Collaboration Toward a Software Stack for Power and Energy Efficiency

Birds of a Feather

While there exist several standalone efforts that attempt to tackle exascale power and energy challenges, the majority of the implemented techniques have been designed to meet site-specific needs. There is no consensus among the stakeholders in academia, research and industry on which software components of modern HPC stack should be deployed and how they should interoperate. Coordination among these components is critical towards maximizing a target metric (such as FLOPS per watt) while meeting operating constraints (such as energy).

This realization led to the formation of the (PowerStack Community)[] in 2016. Its charter is to identify what power optimization software actors are needed, how they interoperate to streamline the optimization goals, and how to glue together existing open source production software for a cost-effective yet cohesive, cross-platform implementation of the software stack.

This interactive vendor-neutral BoF will provide a platform to bring together the stakeholders from academia, research and industry to participate in this consortium and work towards fine-tuning the stack. The vision of this BoF is to share lessons learned through prototyping efforts, provide progress updates, invite audience feedback on current directions, brainstorm solutions to open questions, and issue a call-for-collaboration.
