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

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

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

NCCL es una biblioteca de comunicación de alto rendimiento y un framework de computación distribuida en GPU diseñado para ejecutar intercambios de datos colectivos y punto a punto a través de múltiples GPUs en sistemas de uno o varios nodos. Sirve como capa de transporte RDMA para GPU y orquestador de memoria, facilitando la sincronización de gran ancho de banda de datos y gradientes de modelos para el entrenamiento e inferencia distribuida en GPU. La biblioteca se distingue por su capacidad para ejecutar primitivas de comunicación directamente desde kernels de GPU, eliminando la CPU anfitriona del camino crítico. Utiliza la selección de rutas consciente de la topología para optimizar el movimiento de datos y emplea transporte de red basado en RDMA, incluyendo InfiniBand y NVLink, para permitir el acceso a memoria de copia cero entre dispositivos a través de diferentes nodos físicos. El proyecto cubre una amplia gama de patrones de comunicación colectiva, incluyendo reducciones, broadcasts, gathers e intercambios all-to-all, junto con acceso remoto a memoria punto a punto. Proporciona una gestión integral de comunicadores para inicializar, particionar y redimensionar grupos de GPU, así como una gestión de memoria especializada para registrar buffers y coordinar memoria compartida de dispositivo. El sistema incluye un conjunto de herramientas de monitoreo y observabilidad para el seguimiento de la salud, registro de diagnósticos y monitoreo de eventos en tiempo real, así como interfaces de integración para frameworks de aprendizaje automático, CUDA graphs, MPI y Python.
