Linus Tech Tips (LTT): They let me take apart a SUPER COMPUTER

They snagged exclusive access to Canada’s newest $82 million academic supercomputer at Simon Fraser University, tearing down liquid-cooled nodes that pack 640 Nvidia GPUs, EPYC Genoa CPUs, 1.152 TB of DDR5 and blazing-fast HBM3 memory (3.36 TB/s!). You’ll see direct-die cooling loops, Aquatherm tubing, 600 kW cooling distribution units and mammoth evaporative towers—capturing up to 95% of the heat.

Beyond raw compute, they dive into 800 Gbit NDR networking, 49 PB of spinning-rust storage plus 2 PB NVMe, 192- and 400-core CPU configurations, tight security measures and who footed the bill. It’s a whirlwind tour of high-performance plumbing, power delivery and the future of scientific discovery.
