Comprehensive and Detailed Explanation From Exact Extract:
In NVIDIA AI infrastructure, theNVIDIA Fabric Managerservice is responsible for managing GPU fabric features such as NVLink partitioning on HGX systems. This service periodically polls the GPUs to monitor and manage NVLink states. By default, the GPU polling subsystem is set toevery 30 secondsto balance timely updates with system resource usage.
This polling interval allows the Fabric Manager to efficiently detect and respond to changes or issues in the NVLink fabric without excessive overhead or latency. It is a standard default setting unless specifically configured otherwise by system administrators.
This default behavior aligns with NVIDIA’s system management guidelines for HGX platforms and is referenced in NVIDIA AI Operations materials concerning fabric management and troubleshooting of NVLink partitions.
