ISC20 Featured Demo: Running Multiple Workloads on a Single A100 GPU

AI-Generated Summary

  • The NVIDIA A100 Tensor Core GPU introduces Multi-Instance GPU (MIG) technology that partitions a single GPU into up to seven instances with dedicated compute, memory, and bandwidth.
  • MIG enables multiple users to run workloads simultaneously on the same GPU, maximizing per-GPU utilization and user productivity.
  • A single A100 GPU can run an HPC simulation, AI inference, and debugging session concurrently, replacing what previously required three separate GPUs.

The NVIDIA A100 Tensor Core GPU includes a groundbreaking feature called Multi-Instance GPU (MIG), which partitions the GPU into as many as seven instances, each with dedicated compute, memory, and bandwidth. 

This allows multiple users to run their workloads on the same GPU, maximizing per-GPU utilization and user productivity. 

This demo runs an HPC simulation, an AI inference, and a debugging session simultaneously on a single A100 GPU. In the past, this would have required 3 GPUs and can now be addressed with a single A100 with one more slice to spare.

The NVIDIA Tensor Core A100 GPU’s MIG feature allows system admins to maximize GPU utilization by running more workloads on the same GPU and gives users faster access to run their simulations.
