Fit to programme

This was a proposed solution answering Task 023: Power management, behind WP 1.1.

Summary

This proposal explores simple methods for HPC system dynamic power capping in response to external factors such as grid supply pricing and spot carbon intensity. We will study the control achievable from a system perspective, and will also explore the feasibility of dynamically controlling power based on external inputs, and seek to demonstrate a prototype implementation using the COSMA HPC facility.

We will investigate multiple power control techniques, and study the impact that these have on the scientific output of codes, drawing pragmatic conclusions based around total cost of ownership and total carbon produced.

We will showcase our findings at national and/or international conferences, and will deliver a white paper to be hosted on the SHAREing website.

Outputs

A white paper for the SHAREing website, and presentations at conferences, events or workshops.

We will also seek to deliver a working prototype system capable of reducing power demand in response to carbon intensity or grid pricing, and seek to place this into production should reliability be proved.
