GPU Optimization Patterns

To optimize PyTorch GPU memory usage, you can profile memory consumption and apply mixed-precision training using BF16 or FP16 with autocast. This Skill provides patterns to estimate memory for models and optimizers to prevent out-of-memory errors.

The best way to use torch.compile for performance gains is selecting the appropriate mode. This Skill covers applying torch.compile with default, reduce-overhead, and max-autotune modes to accelerate your deep learning workflows.

Yes, you can load large language models in 4-bit quantization using bitsandbytes. This Skill provides expert patterns for loading models in 4-bit precision to significantly reduce your GPU memory footprint.

PyTorch mixed precision training with BF16 and FP16 uses autocast for automatic casting. This Skill details implementing mixed-precision training, covering the application of GradScaler alongside autocast to optimize GPU throughput.

Your PyTorch DataLoader might cause GPU training bottlenecks due to suboptimal configuration. This Skill helps you configure the DataLoader for maximum GPU throughput and utilize torch.profiler to identify training step bottlenecks.

Yes, you need torch and transformers to implement these GPU profiling and optimization patterns. This Skill requires PyTorch, bitsandbytes, and transformers libraries to fully support memory management, profiling, and quantization tasks.
