Setting Up Ollama for High-Throughput Computing

Why Choose Ollama?

System Requirements

• Operating System: Ubuntu Linux or macOS (Windows support is still being finalized).
• RAM: A minimum of 8GB for smaller models like the 7B variants & up to 32GB for larger models.
• Disk Space: Allocating about 12GB for the Ollama installation, plus additional space for model data.
• GPU: Not strictly required, but if you want to leverage the full power of Ollama, a compatible NVIDIA GPU enhances speed significantly.

Steps to Install Ollama

1. Open a terminal: If you’re using macOS, you can use the built-in Terminal app. On Linux, access your command line interface.
2. Install Ollama: You can easily install Ollama using a simple curl command in your terminal, like so:
   1 2 bash curl -fsSL https://ollama.ai/install.sh | sh
   This script automates the installation process.
3. Verify Installation: Once the installation is complete, you can verify if Ollama is running smoothly by executing:
   1 2 bash ollama --version
   If you see the version number, congratulations! You’ve successfully set up Ollama.

Understanding Throughput

Optimizing Ollama’s Performance

1. Adjust Parallelism Settings: Turn on parallel processing with environment variables. You can optimize the number of parallel requests Ollama can handle simultaneously. For example:

   1 2 bash export OLLAMA_NUM_PARALLEL=4 # Sets the parallel request limit

   Remember, too much parallelism might lead to diminishing returns in performance, so it's wise to tune this setting after initial testing.
2. Use GPU Acceleration:
   If you have a GPU, use it! It can easily boost inference speeds significantly. Set up your system to utilize the GPU by ensuring you’re running on an appropriate NVIDIA model (ideally something with compute capability of at least 5.0).
3. Batch Processing:
   Micro-batch processing can greatly increase throughput for requests. This means processing multiple requests in a single batch rather than one at a time, allowing for better resource usage. ```python import ollama import concurrent.futures
   def process_prompt(prompt): return ollama.generate(model='mistral', prompt=prompt)
   prompts = [ "Summarize benefits of exercise.", "Explain concept of machine learning." ]
   with concurrent.futures.ThreadPoolExecutor(max_workers=3) as executor: results = list(executor.map(process_prompt, prompts)) print(results) ```

System Resource Management

• Monitor Server Resource: Keep an eye on CPU, memory, and GPU utilization. Tools like
  1 htop
  or
  1 nvidia-smi
  can help here.
• Limit Background Processes: Reduce resource hogs by shutting down unnecessary processes running in the background. This allows Ollama’s processes to take priority and operate smoothly.

Building an Ollama Cluster

Why Set up a Cluster?

• Higher Availability: Distributing the load means better uptime and accessibility.
• Load Balancing: A clustered setup can manage the load more evenly across different nodes, preventing bottlenecks.
• Scalability: As demand increases, it’s easier to scale out your setup by adding more nodes.

Setting Up a Cluster

1. Choose Your Nodes: Select machines you want to incorporate into your cluster. Ensure their hardware meets or exceeds Ollama's basic requirements.
2. Networking: Make sure your network is configured to support inter-node communication.
3. Shared Storage: Implement a shared storage solution like NFS (Network File System) so all nodes have access to the same resources.
4. Using Docker Containers: Docker can simplify clustering by allowing you to run multiple isolated instances of Ollama easily.
   1 2 3 bash docker run -d --gpus=all --name ollama-instance-1 ollama/ollama docker run -d --gpus=all --name ollama-instance-2 ollama/ollama
5. Customize Configuration: Use environment variables to adjust the parameters for optimal performance based on your workload.
