Compute Clusters Break Out Of National Labs To Scale AI

Key Takeaways: A cluster comprises a group of interconnected servers (aka nodes) across multiple racks, connected via Ethernet and increasingly via optical links, and is ideal for workloads that are so large and require so much compute that a single rack of servers cannot do the job. Design challenges include network congestion, latency and stragglers, power delivery, thermal limits, software scheduling, performance and scalability, and power and energy. Clusters are already deployed in national
