GitHub - NVIDIA/multi-gpu-programming-models: Examples demonstrating available options to program multiple GPUs in a single node or a cluster
This project implements the well known multi GPU Jacobi solver with different multi GPU Programming Models: single_threaded_copy Single Threaded using cudaMemcpy for inter GPU communication multi_threaded_copy Multi Threaded with OpenMP using cudaMemcpy for inter GPU communication multi_threaded_copy_overlap Multi Threaded with OpenMP using cudaMemcpy for itner GPU communication with overlapping c
Horovod hangs -- include/shm.h:42 NCCL WARN Cuda failure 'invalid argument' · Issue #893 · horovod/horovod
Hi, I am trying to get Horovod trainings running on a cluster built from Nvidia RTX 2080 ti GPUs and Infiniband interconnects. Installed software: Ubuntu 16.04.5 LTS Cuda 10.0.130-1 NCCL 2.4.2-1+cuda10 Open MPI 3.1.2 Mellanox OFED 4.4-2.0.7.0 Tensorflow 1.13.1, custom built without XLA support Horovod 0.16 This is the device topology (PCI express dual root): $ nvidia-smi topo -m GPU0 GPU1 GPU2 GPU
