Researchers at the Georgia Institute of Technology are focusing on improving datacenter cooling
Joshi and his students have assembled a small high-power-density datacenter on the Georgia Tech campus that includes different types of cooling systems, partitions to change room volumes and both real and simulated server racks. They use fog generators and lasers to visualize air flow patterns, infrared sensors to quantify heat, airflow sensors to measure the output of fans and other systems, and sophisticated thermometers to measure temperatures on server motherboards.
Beyond studying the effects of alternate airflow patterns, they are also verifying that cooling systems are doing what they’re supposed to do. Because tasks are dynamically assigned to specific machines, heat generation varies in a datacenter. Joshi’s group is also exploring algorithms that could help even out the computing load by assigning new computationally-intensive tasks to cooler machines, avoiding hot spots.
