Overview

Framework SCARF calculates Adjusted Water Impact by incorporating water stress in computing, highlighting optimization opportunities.

Key Points

  • Adjusted Water Impact metric reveals important opportunities for reducing water consumption in computing.
  • SCARF accounts for spatial and temporal variations in water stress, improving sustainability measures in AI workloads.
  • Case studies on datacenters and semiconductor plants demonstrate the framework's practical applications for optimizing water usage.
  • The approach supports efforts towards sustainable computing, indicating future pathways for minimizing water impact.
