How do I optimize TensorFlow or PyTorch for multi-GPU training?
Optimizing TensorFlow or PyTorch for multi-GPU training takes a mix of hardware choices, software setup, and training strategy. Here’s what works. 1. Hardware Setup Connect GPUs with high-bandwidth links — NVLink on NVIDIA cards — to cut communication overhead. Use PCIe Gen4 or NVLink for faster GPU-to-GPU data transfer. Keep thermals in check. Thermal throttling […]
