Notebook/Pipeline

Your ML Pods/Containers with WoolyAI Runtime libraries

Your Shared GPU Pool (NVIDIA) with WoolyAI Server Hypervisor

Kernel-level Scheduling

Safe VRAM Overcommit

Model Weight Dedup in VRAM

A New way to share GPUs: Deterministic Kernel Scheduling, VRAM OverCommit, and Shared Model Weights

What WoolyAI Does

Increases NVIDIA GPU utilization

Pack more notebooks, experiments, and training jobs onto each GPU—without noisy neighbors.

Reduces queue times and idle GPUs

Small jobs start immediately, rather than waiting behind long-running workloads or reserving entire GPUs.

Improves GPU Cluster Utilization and Balance

Balance load across the cluster and eliminate stranded GPU capacity.

Treat GPUs as a Shared Fabric, Not Fixed Nodes

GPU scheduling is no longer tied to container placement enabling higher cluster efficiency, and shorter wait times.

How It’s Different

Kernel-Level Scheduling, Not Slicing

WoolyAI schedules GPU compute at the kernel level, allocating GPU cores with deterministic, SLA-based guarantees instead of GPU-slicing or coarse job-level time-slicing.

GPU VRAM Virtualization and Overcommit

GPU memory is treated as a managed, virtual resource—allowing safe VRAM overcommit so multiple workloads can share memory efficiently.

Model Weight Deduplication

Identical model weights are loaded once and shared across applications, eliminating redundant VRAM usage and enabling more workloads per GPU.

Decouples CPU and GPU Execution

Option to run ML containers on CPU, while all GPU operations are transparently executed on a shared GPU pool—no code changes required.

Built for MLOps & ML Platform Teams

Notebooks & Interactive Dev

Let 20–50 researchers share a small GPU pool without noisy neighbors or queueing.

  • Eliminate GPU idling when the notebook is inactive
  • Researchers get immediate GPU access for notebooks and experiments, even with a limited GPU pool

HPO, Sweeps & Ablations

Run 2-5x more experiments per GPU without new hardware

  • Execute multiple independent trials concurrently on the same GPU.
  • Control execution SLA for trials with deterministic kernel level scheduling
  • Pack more per GPU with safe VRAM overcommit and DeDup

4. Inference and Multi-Tenant Serving

Guarantee latency for critical endpoints while filling idle SMs with background jobs.

  • Priority tiers mapped to kernel scheduling SLAs
  • Share GPU for Inference and other background jobs
  • Model Weights Deduplication in VRAM for identical model serving

Fine-Tuning & Parameter-Efficient Training (LoRA / adapters)

Run many fine-tuning jobs simultaneously without scaling the GPU count.

  • Multiple fine-tuning jobs share a large frozen base model
  • Only small adapter weights differ between runs
  • Shared base model loaded once in VRAM instead of multiple copies

Co-Exists With Your Existing ML Platform

Integration Model

  • Requires no changes to your existing ML containers – WoolyAI libraries injected automatically 
  • WoolyAI Hypervisor software runs on GPU nodes, creating a shared GPU pool.
  • Kubernetes-WoolyAI plugin lets Kubernetes schedule pods on Wooly Hypervisor-managed GPU Nodes
  • No need to change your existing CI/CD tools or manage new tools.
