FMplex: Model Virtualization for Serving Extensible Foundation Models
TL;DR
Existing model-serving systems deploy each customized task as a separate model instance, leading to inefficient use of resources. FMplex is a serving system that virtualizes foundation model (FM) backbones, allowing multiple tasks to share a single model instance.
✦ Why It Matters
Engineers can implement FMplex to optimize resource usage and improve the efficiency of AI model deployment.
Key Takeaways
- Adopt FMplex for efficient model serving in your applications.
- Utilize virtual foundation models to share resources across tasks.
- Implement batch-aware scheduling to improve task performance.
- Explore the potential of hosting more tasks with reduced latency.
How It Works
FMplex creates virtual foundation models (vFMs) that act as private instances for each task while sharing a common physical foundation model. This allows for efficient resource utilization and task-specific customizations.
The batch-aware fair-queueing scheduler further enhances performance by optimizing how tasks are processed together, balancing load and minimizing latency.
