In the fast-paced world of artificial intelligence and deep learning, companies are realizing that standard High Performance Computing (HPC) solutions might not be the best solution for their AI infrastructure requirements. In this in-depth analysis we will discover why Slurm, even if it is widely adopted in the HPC community, lacks the requirements of modern Deep Learning workloads.
Exploring the Deep Learning Infrastructure Problem
Changes in Computing Requirements
Deep learning workloads are fundamentally different from traditional HPC tasks:
- GPU Utilization Patterns in High-intensity Tasks
- Dynamic resource requirements
- Extended training sessions
- Complex data dependencies
- Interactive development needs
The Old HPC versus New AI Demands
Although there is some commonality between HPC and AI workloads, they are very different:
- Resource allocation patterns
- Job scheduling requirements
- Development workflow needs
- Requirements for flexible infrastructure
- Considerations for production deployment
