Example of a Multi-GPU Setup
For a high-end multi-GPU setup, consider the following:
- Motherboard: A motherboard with multiple PCIe slots, preferably supporting PCIe 4.0 for higher bandwidth.
- Power Supply Unit (PSU): A robust PSU with enough power and connectors for multiple GPUs.
- Cooling Solutions: Adequate cooling (both air and liquid cooling options) to manage the heat output of multiple GPUs.
Configuration Tips
- BIOS Settings: Ensure the BIOS is configured to support multi-GPU setups.
- Driver Installation: Install the latest NVIDIA drivers that support multi-GPU configurations.
- Framework Configuration: In your deep learning framework, configure the settings to utilize multiple GPUs (e.g., using torch.nn.DataParallel or torch.distributed in PyTorch).
Summary
By focusing on high VRAM, CUDA/Tensor cores, NVLink support, and efficient cooling, you can build a powerful multi-GPU setup capable of running large language models locally. Using high-end GPUs like the NVIDIA RTX 3090 or the A100 will provide the performance needed for demanding AI tasks.
Budget Build: Objective: Maximize performance while minimizing costs.
Components:
- Two NVIDIA GeForce RTX 3060 12GB GPUs
Reason: The RTX 3060 provides a good balance of performance and cost. With 12GB of VRAM, it can handle moderate LLM inference tasks effectively.
- Two NVIDIA Tesla K80 GPUs (24GB, dual-GPU card)
Reason: The Tesla K80 is an older model but still provides considerable compute power for a very low price. Each card effectively has two GPUs, giving you access to four GPUs within the two slots, maximizing the use of available PCIe slots.
Configuration
- Slot 1: NVIDIA GeForce RTX 3060
- Slot 2: NVIDIA GeForce RTX 3060
- Slot 3: NVIDIA Tesla K80
- Slot 4: NVIDIA Tesla K80
Approximate Cost: $1,500 - $2,000
