Applications
- Training and fine-tuning neural networks.
- LLM and other neural-network inference.
- Scientific simulations and GPU-accelerated data analysis.
Compatibility
- This is an SXM module, not a PCIe expansion card. It needs a matching GPU baseboard, firmware, power delivery and cooling validated by the server manufacturer. SXM generations are not interchangeable.
- Memory belongs to individual GPUs. NVLink does not automatically turn it into one GPU's local memory; using multiple GPUs requires software that distributes the model or workload.
- Check driver, CUDA/framework and operating-system support for the intended workload. Virtualization and enterprise software may require separate licenses and a supported host configuration.
