Algorithm cuts data center emissions by 83% through smart task scheduling
Researchers have developed an optimization technique that dramatically reduces carbon emissions from edge computing systems by intelligently routing computational tasks and managing battery charging. The breakthrough matters for companies operating distributed data centers: as regulatory pressure on emissions intensifies, this approach offers a concrete way to slash environmental impact without major infrastructure overhauls.
Originaltitel: Less Carbon Footprint in Edge Computing by Joint Task Offloading and Energy Sharing
<p>We address reducing carbon footprint (CF) in the context of edge computing. The carbon intensity of electricity supply largely varies spatially as well as temporally. We consider optimal task scheduling and offloading, as well as battery charging to minimize the total CF. We formulate this optimization problem as a mixed integer linear programming model. However, we demonstrate that, via a graph-based reformulation, the problem can be cast as a minimum-cost flow problem, and global optimum can be admitted in polynomial time. Numerical results using real-world data show that optimization can reduce up to 83.3% of the total CF.</p>
