NVIDIA moves data between local or remote storage and GPU memory using a direct-memory access engine to bypass the CPU.
Warp is a Python framework that JIT-compiles Python functions into CUDA kernels for GPU-accelerated parallel computation, with built-in automatic differentiation and multi-framework array interoperability. At its core, it provides a GPU kernel compilation system that enables writing and executing custom GPU kernels directly from Python, while supporting automatic gradient computation through those kernels for integration with machine learning pipelines. The framework also includes tile-based cooperative computing, where thread blocks partition into tiles for shared-memory and tensor-core opera
Permits one GPU to directly read or write memory allocated in another GPU's pool for accelerated cross-device transfers.
NCCL ist eine Hochleistungs-Kommunikationsbibliothek und ein Framework für verteiltes GPU-Computing, das für die Ausführung kollektiver und Punkt-zu-Punkt-Datenaustausche über mehrere GPUs in Einzel- oder Multi-Node-Systemen entwickelt wurde. Es dient als RDMA-GPU-Transportschicht und Speicher-Orchestrator, der die hochbandbreitige Synchronisation von Daten und Modellgradienten für verteiltes GPU-Training und Inference erleichtert. Die Bibliothek zeichnet sich durch ihre Fähigkeit aus, Kommunikationsprimitive direkt aus GPU-Kernels auszuführen, wodurch die Host-CPU aus dem kritischen Pfad entfernt wird. Sie nutzt topologiebewusste Pfadauswahl zur Optimierung der Datenbewegung und verwendet RDMA-basierten Netzwerktransport, einschließlich InfiniBand und NVLink, um Zero-Copy-Speicherzugriffe zwischen Geräten über verschiedene physische Knoten hinweg zu ermöglichen. Das Projekt deckt eine breite Palette an kollektiven Kommunikationsmustern ab, darunter Reduktionen, Broadcasts, Gathers und All-to-All-Austausche, neben Punkt-zu-Punkt-Remote-Speicherzugriffen. Es bietet umfassendes Communicator-Management für die Initialisierung, Partitionierung und Größenanpassung von GPU-Gruppen sowie spezialisiertes Speichermanagement für das Registrieren von Buffern und das Koordinieren von gemeinsam genutztem Gerätespeicher. Das System enthält eine Suite von Monitoring- und Observability-Tools für Health-Tracking, diagnostisches Logging und Echtzeit-Ereignisüberwachung sowie Integrationsschnittstellen für Machine-Learning-Frameworks, CUDA-Graphs, MPI und Python.
NCCL reads or writes data directly to a remote registered memory window without requiring the target process's active participation.
