What is NCCL?
NVIDIA Collective Communications Library (NCCL) is a library for multi-GPU and multi-node collective communication primitives. It provides optimized routines for data transfer and synchronization across multiple GPUs, enabling faster training of deep learning models and other parallel applications. It is commonly used in distributed deep learning frameworks like TensorFlow, PyTorch, and MXNet to accelerate model training.
What other technologies are related to NCCL?
NCCL Competitor Technologies
OneCCL
No summary available
OneCCL is a communication library from Intel designed for collective communication, serving a similar purpose as NCCL but for different hardware.
NVSHMEM
No summary available
NVSHMEM provides a shared memory programming model across multiple GPUs, presenting an alternative to NCCL for certain inter-GPU communication patterns.
MPI
MPI (Message Passing Interface) is a standard for inter-process communication, offering collective communication operations that compete with NCCL, although NCCL focuses specifically on GPU collectives.
ROCm
ROCm is AMD's platform for GPU computing, and while not directly a communication library, it represents a competing ecosystem to CUDA where NCCL operates. Alternatives to NCCL may exist within ROCm.
NCCL Complementary Technologies
UCX
