Building on this foundation, we optimize the software and orchestration stack to maximize mean-time between interruptions (MTBI) and minimize mean-time to recovery (MTTR) through two primary areas:
-
Observability: Reliability at scale requires high-fidelity visibility. We use sub-millisecond telemetry to monitor network systems. This deep visibility allows us to detect transient congestion, optimize buffer management, and pinpoint the root causes of slowdowns across the hardware and software stack.
-
Identifying stragglers and hangs: Proactive monitoring is critical for identifying nodes that are experiencing performance degradation (stragglers) or that have stopped responding completely (hangs). By rapidly localizing these bottlenecks, with automated straggler and newly added hang detection, we accelerate the training job and protect it from localized slowdowns.
The foundation of the AI Hypercomputer
Virgo Network is a reimagined scale-out data center network custom-built for the stringent demands of modern AI workloads. This flat, multi-planar architecture unifies accelerators across pods into a single compute domain, addressing the bandwidth and scale limitations of traditional networks. By providing robust fault isolation directly at the hardware level, Virgo Network serves as the foundation for system-wide resilience, protecting synchronized workloads from localized hardware faults.
Ultimately, Virgo Network delivers the scale, predictable latency, and reliability necessary to accelerate the agentic AI era.
