OpenAI unveils MRC networking protocol to boost AI training resilience and speed

OpenAI has developed a new networking protocol called MRC (Multipath Reliable Connection) to address performance bottlenecks in large-scale AI training. This protocol, released through the Open Compute Project, spreads data transfers across hundreds of paths simultaneously to prevent congestion and recovers from failures within microseconds. MRC aims to significantly reduce GPU idle time and improve the efficiency of training massive AI models, potentially increasing training speeds by up to 40%. AI
