Building Prometheus: How Backend Aggregation Enables Gigawatt-Scale AI Clusters
Backend aggregation (BAG) is crucial for Meta's gigawatt-scale AI clusters, like Prometheus, by connecting thousands of GPUs across various data centers using Disaggregated Schedule Fabric (DSF) and Non-Scheduled Fabric (NSF).
MAIN POINTS
- BAG connects thousands of GPUs across multiple data centers and regions.
- It integrates two network fabrics: Disaggregated Schedule Fabric (DSF) and Non-Scheduled Fabric (NSF).
- This integration is essential for building gigawatt-scale AI clusters.
- Prometheus is an example of such a cluster enabled by BAG.
TAKEAWAYS
- BAG plays a pivotal role in scaling AI infrastructure at Meta.
- Seamless GPU connectivity is achieved through BAG's network fabric integration.
- The combination of DSF and NSF is innovative in AI cluster development.
- Meta's approach exemplifies advanced data center engineering for AI scalability.
