DeepSpeed is a distributed deep learning optimization library and framework designed for the training and inference of massive AI models. It serves as a model parallelism orchestrator and a toolkit for scaling large language models across multiple GPUs and compute nodes. The project distinguishes itself through 3D parallelism orchestration, which combines data, pipeline, and tensor parallelism. It utilizes ZeRO-based memory partitioning to eliminate redundant storage and employs CPU-offload memory management to move weights and optimizer states to system RAM. Additionally, it provides special
Optimizes distributed training communication using low-precision techniques to reduce data traffic and overhead.
Horovod is a distributed deep learning framework designed to scale machine learning training across multiple GPUs and nodes. It functions as an orchestrator for multi-GPU scaling and a tool for distributed gradient averaging, allowing users to increase compute capacity without rewriting core model logic. The project provides a consistent communication interface that supports multi-framework model distribution across TensorFlow, PyTorch, Keras, and MXNet. It leverages an MPI distributed training library to synchronize gradients across processes using collective communication operations. The s
Implements communication batching and computation-communication overlapping to reduce overhead and improve scaling efficiency.
Horovod is a distributed deep learning framework and gradient synchronizer designed to scale model training across multiple GPUs and compute nodes. It functions as a distributed training orchestrator and an elastic training engine, utilizing an MPI collective communication library to synchronize weights and gradients across TensorFlow, PyTorch, Keras, and MXNet models. The system distinguishes itself through dynamic elastic scaling, which allows it to adjust the number of active workers at runtime and recover from node failures. It optimizes communication efficiency using tensor fusion batchi
Optimizes collective communication using all-reduce and all-gather operations to synchronize gradients efficiently.
NCCL est une bibliothèque de communication haute performance et un framework de calcul GPU distribué conçu pour exécuter des échanges de données collectifs et point à point sur plusieurs GPU dans des systèmes à un ou plusieurs nœuds. Il sert de couche de transport GPU RDMA et d'orchestrateur de mémoire, facilitant la synchronisation à large bande passante des données et des gradients de modèle pour l'entraînement et l'inférence GPU distribués. La bibliothèque se distingue par sa capacité à exécuter des primitives de communication directement depuis les noyaux (kernels) GPU, supprimant le CPU hôte du chemin critique. Elle utilise une sélection de chemin consciente de la topologie pour optimiser le mouvement des données et emploie un transport réseau basé sur RDMA, incluant InfiniBand et NVLink, pour permettre un accès mémoire zéro-copie entre les appareils sur différents nœuds physiques. Le projet couvre un large éventail de modèles de communication collective, notamment les réductions, les diffusions (broadcasts), les rassemblements (gathers) et les échanges tous-à-tous, ainsi que l'accès mémoire distant point à point. Il fournit une gestion complète des communicateurs pour initialiser, partitionner et redimensionner les groupes GPU, ainsi qu'une gestion spécialisée de la mémoire pour enregistrer les tampons (buffers) et coordonner la mémoire partagée des appareils. Le système inclut une suite d'outils de surveillance et d'observabilité pour le suivi de la santé, la journalisation diagnostique et la surveillance des événements en temps réel, ainsi que des interfaces d'intégration pour les frameworks de machine learning, les graphes CUDA, MPI et Python.
Allows suspending communicator operations to temporarily release dynamic memory and resume them later.
RLinf is a distributed reinforcement learning orchestrator and embodied AI training framework. It provides the infrastructure to train vision-language-action models and robotic policies using a combination of reinforcement learning and supervised fine-tuning. The system is designed for scaling workloads across GPU clusters, managing the placement of actors, rollout workers, and environment components. It features a specialized robotics data collection pipeline for gathering teleoperated demonstrations and simulation trajectories into standardized replay buffers, alongside a hardware interface
