Ferveret, an MIT spinout, has adapted nuclear reactor heat transfer techniques to create a liquid cooling system for data centers that improves computational power efficiency by 15% and allows 35% more tokens per watt, using zero water.
Jane Street revealed inside views of its AI training center in Texas, housing 4,032 GPUs, 8,000 kilometers of fiber optics, and a full liquid cooling system, while recounting the 20-year evolution from a humble start with six Dell hosts to today's extreme trading system.
Jane Street's tech lead Ron Minsky and physical engineering team lead Daniela Corvo gave a tour of a Texas data center retrofitted for high-density liquid-cooled GPU training, detailing liquid cooling systems, power distribution challenges, leak detection, and the opportunity cost of compute resources.
