Getting Started with DGX Spark

Congratulations on your new NVIDIA DGX Spark! This guide will walk you through the initial setup process and help you run your first AI models.

Initial Setup

1. Hardware Setup

  1. Unpack the System: Carefully remove the DGX Spark from its packaging
  2. Connect Power: Attach the power supply
  3. Network Connection: Connect to your network via Ethernet (recommended) or WiFi
  4. Peripherals: Connect keyboard, mouse, and display

2. First Boot

The DGX Spark comes with the NVIDIA AI software stack pre-installed. On first boot:

  1. Follow the on-screen setup wizard
  2. Create your user account
  3. Configure network settings
  4. Update system components if prompted

3. System Updates

Keep your system up to date:

sudo apt update
sudo apt upgrade

Pre-installed Software

Your DGX Spark includes:

  • NVIDIA Drivers: Latest GPU drivers
  • CUDA Toolkit: Complete CUDA development environment
  • NVIDIA NIM: Optimized model deployment platform
  • Docker: Container platform for AI workloads
  • Python: Python 3.x with pip
  • AI Frameworks: PyTorch, TensorFlow (can be installed via containers)

Running Your First Model

Using NVIDIA NIM

NVIDIA NIM provides optimized inference for popular models:

# Pull a model container
docker pull nvcr.io/nvidia/nim/meta/llama-3-8b-instruct:latest

# Run the model
docker run --gpus all -p 8000:8000 \
  nvcr.io/nvidia/nim/meta/llama-3-8b-instruct:latest

Using Ollama

Ollama is pre-configured for easy model management:

# Install Ollama (if not already installed)
curl -fsSL https://ollama.com/install.sh | sh

# Run a model
ollama run llama3

# Or try DeepSeek
ollama run deepseek-r1

Using Python

Create a simple Python script to test the system:

import torch

# Check CUDA availability
print(f"CUDA Available: {torch.cuda.is_available()}")
print(f"CUDA Device: {torch.cuda.get_device_name(0)}")

# Simple tensor operation
x = torch.randn(1000, 1000, device='cuda')
y = torch.randn(1000, 1000, device='cuda')
z = torch.matmul(x, y)

print("Matrix multiplication completed successfully!")

Recommended Workflows

1. Model Fine-Tuning

Use NVIDIA AI Workbench for streamlined fine-tuning:

  1. Install AI Workbench from nvidia.com/ai-workbench
  2. Create a new project
  3. Select your base model
  4. Configure fine-tuning parameters
  5. Start training

2. Local Inference Server

Set up a local inference server:

# Using FastAPI and transformers
pip install fastapi uvicorn transformers torch

# Create your inference endpoint
# See our detailed tutorial at /blog/dgx-spark-inference-server

3. Development Environment

Configure your preferred IDE:

  • VS Code: Install Remote-SSH extension for remote development
  • Jupyter: Access via browser at http://localhost:8888
  • PyCharm: Configure remote interpreter

Performance Optimization Tips

Memory Management

  • Monitor memory usage: nvidia-smi
  • Use mixed precision training (FP16/BF16)
  • Leverage NVIDIA's optimized libraries

Model Selection

  • Start with smaller models for testing
  • Scale up based on your requirements
  • Use quantized models for inference (FP4/INT8)

Container Usage

  • Use NVIDIA NGC containers for optimized performance
  • Cache containers locally to save download time
  • Organize projects with Docker Compose

Networking Two DGX Spark Systems

For models up to 405B parameters, connect two systems:

  1. Connect systems via NVIDIA ConnectX networking
  2. Configure multi-node training
  3. Use NVIDIA's distributed training libraries

Troubleshooting

Common Issues

System doesn't boot:

  • Check power connection
  • Verify display connection
  • Try recovery mode (see documentation)

CUDA not detected:

# Check NVIDIA driver
nvidia-smi

# Reinstall if needed
sudo apt install --reinstall nvidia-driver-XXX

Model fails to load:

  • Check available memory
  • Verify model compatibility
  • Try a smaller model size

Resources

Next Steps

Now that you're set up, explore:

  1. Fine-tune a model on your own data
  2. Build a local RAG system
  3. Experiment with multimodal models
  4. Develop edge AI applications

Happy developing with your DGX Spark!
