OpenAI has introduced a new supercomputer networking protocol called Multipath Reliable Connection (MRC). This protocol is designed to improve the resilience and performance of large-scale AI training clusters. MRC is released through the Open Compute Project (OCP) to enable more efficient and reliable communication between nodes in these clusters. By using multiple paths for data transmission, MRC aims to reduce latency and increase overall system reliability. --- Why it matters: This matters because it can help improve the efficiency of large-scale AI training networks, which are critical for developing and deploying advanced AI models. Engineers working on such projects will be interested in how MRC can enhance their systems' performance and resilience. Source: https://openai.com/index/mrc-supercomputer-networking
