GPUlayer: Train PyTorch on every GPU you can reach-faster than PyTorch Lightning (www.gpulayer.dev)

GPUlayer has launched a new training framework that empowers users to efficiently train PyTorch models across multiple GPUs and machines, outperforming PyTorch Lightning in performance benchmarks. This robust tool enables seamless scaling from individual laptops to large clusters by automatically selecting optimal machines and GPUs, managing processes, and compiling logs, checkpoints, and metrics. In tests, GPUlayer exhibited faster training times in 13 out of 17 GPU scenarios and every CPU case, highlighting its potential for enhancing productivity in AI/ML workflows. Significantly, GPUlayer's versatility lies in its ability to operate across various environments, from local setups to cloud platforms like AWS and Google Cloud, and supports diverse hardware architectures, including CUDA and Apple Metal. The framework includes a complete training API, allowing users to implement distributed data parallelism (DDP), fully sharded data parallelism (FSDP), and tensor parallelism—all managed under one simplified interface. This advanced capability not only streamlines the setup process but also optimizes resource usage, making GPUlayer a compelling choice for AI practitioners seeking to maximize training efficiency.
