Episode 18 - Why AI needs a new kind of supercomputer network
Mark Handley, a longtime networking researcher and UCL professor, and Greg Steinbrecher, a GPU-cluster engineer optimizing large-scale training, explain how AI training breaks traditional networks. They discuss why synchronous GPU workloads stall on small faults, how Multipath Reliable Connection sprays traffic and trims packets to avoid failures, and why making this open standard can lower cost and boost reliability for massive GPU fleets.
