Scale your GPU workloads with Karpenter and Argo Workflows

Amine Saboni
Pruna AI
Abstract

Running ML workloads on Kubernetes can be a burden to manage, especially when the usages tend to diversify. Batch inference will involve different constraints as experimentation, evaluation or serving ML models for user-facing applications.

  • How to assign the correct GPUs for each usage ?
  • How to scale differently workloads with flexibility ?
  • How to efficiently scale down to 0, when no GPUs are needed ?

To answer those questions, we will see in this talk how combine the standard orchestration approach of Argo Workflows with the autoscaling super powers of Karpenter, a tool developed by AWS and given back to the community. We'll dig into the difficulties of scaling GPUs and how Karpenter solves them, with a return of experience of Pruna's computing platform.
