Use GPUs that support NVIDIA Multi-Instance GPU (MIG) to improve utilization and reduce hardware requirements. MIG partitions a single physical GPU into multiple isolated instances, enabling multiple models or workloads to run concurrently on the same GPU.

An iQ Studio agent that uses a RAG pipeline runs these models in parallel:

  • Embedding model
  • Reranker model
  • Inference (LLM) model

With MIG-enabled GPUs, assign each model to a separate MIG instance to consolidate workloads on fewer physical GPUs.

GPUs that don’t support MIG require one dedicated GPU per model, even when a model does not fully use available GPU memory. In this configuration, the RAG pipeline requires at least three GPUs. NVIDIA L40s GPUs do not support MIG.
