GPU Virtualization with MIG: Multi-Tenant Isolation for AI Inference Workloads

2026-01-31T18:00:00+01:00 for 00:30

Serving large video diffusion models to multiple concurrent users sounds challenging till you partition a GPU correctly.

This talk is a deep technical exploration of running large-scale video generation inference on modern GPUs across Hopper and Blackwell with Multi-Instance GPU (MIG) isolation.

We'll explore:

  1. GPU MIG topology: Memory hierarchy, interconnect partitioning, and leveraging high-bandwidth memory effectively.
  2. Memory profiling for inference: Tracking GPU memory allocation across the generation pipeline
  3. MIG profile selection: Choosing partition sizes—when isolation beats raw throughput
  4. Request scheduling: Fair queuing for heterogeneous workloads and batch sizes
  5. Failure modes: OOM recovery, MIG instance health checks, and graceful degradation strategies
  6. Monitoring at scale: Per-instance GPU metrics and detecting performance bottlenecks

Whether you're building a multi-tenant inference platform, optimizing GPU utilization for your team, or exploring how to serve video diffusion models cost-effectively, this talk provides practical configurations for your AI workloads.
