The MIT researchers instead offloaded all of the manual coding to machines. In a paper being presented at SIGCOMM, they describe a system that leverages “reinforcement learning” (RL), a trial-and-error machine-learning technique, to tailor scheduling decisions to specific workloads in specific server clusters.

To do so, they built novel RL techniques that could train on complex workloads. In training, the system tries many possible ways to allocate incoming workloads across the servers, eventually finding an optimal tradeoff in utilizing computation resources and quick processing speeds. No human intervention is required beyond a simple instruction, such as, “minimize job-completion times.”

Compared to the best handwritten scheduling algorithms, the researchers’ system completes jobs about 20 to 30 percent faster, and twice as fast during high-traffic times. Mostly, however, the system learns how to compact workloads efficiently to leave little waste. Results indicate the system could enable data centers to handle the same workload at higher speeds, using fewer resources.
