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 este o bibliotecă de comunicare de înaltă performanță și un framework de calcul distribuit pe GPU, conceput pentru executarea schimburilor de date colective și punct-la-punct pe mai multe GPU-uri în sisteme cu un singur nod sau multi-nod. Servește ca strat de transport RDMA pentru GPU și orchestrator de memorie, facilitând sincronizarea cu lățime de bandă mare a datelor și a gradienților de model pentru antrenarea și inferența distribuită pe GPU. Biblioteca se distinge prin capacitatea sa de a executa primitive de comunicare direct din kernel-urile GPU, eliminând CPU-ul gazdă din calea critică. Utilizează selecția de căi conștientă de topologie pentru a optimiza mișcarea datelor și folosește transportul de rețea bazat pe RDMA, inclusiv InfiniBand și NVLink, pentru a permite accesul la memorie zero-copy între dispozitive pe diferite noduri fizice. Proiectul acoperă o gamă largă de tipare de comunicare colectivă, inclusiv reduceri, broadcast-uri, gather-uri și schimburi all-to-all, alături de accesul la memorie la distanță punct-la-punct. Oferă gestionare cuprinzătoare a comunicatorului pentru inițializarea, partiționarea și redimensionarea grupurilor GPU, precum și gestionarea specializată a memoriei pentru înregistrarea bufferelor și coordonarea memoriei partajate a dispozitivului. Sistemul include o suită de instrumente de monitorizare și observabilitate pentru urmărirea stării, logarea diagnostică și monitorizarea evenimentelor în timp real, precum și interfețe de integrare pentru framework-uri de machine learning, CUDA graphs, MPI și Python.
NCCL reads or writes data directly to a remote registered memory window without requiring the target process's active participation.
