Description

My workstation has Quadro RTX 5000 GPU with 16 GB memory, running NVIDIA Driver 470.103.01, and supporting CUDA 11.4.
The output of nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2020 NVIDIA Corporation
Built on Mon_Nov_30_19:08:53_PST_2020
Cuda compilation tools, release 11.2, V11.2.67
Build cuda_11.2.r11.2/compiler.29373293_0

I am able to successfully build and install AMGX following the instructions provided here. Howeve I am unable to run the examples. When I try running the fist example I obtain the following. I am not sure whats the issue since the installation went error free.

visitor@user:~/amgx/build$ examples/amgx_capi -m ../examples/matrix.mtx -c ../src/configs/FGMRES_AGGREGATION.json
AMGX version 2.5.0
Built on Jan 23 2025, 11:28:13
AMGX ERROR: file /home/visitor/amgx/examples/amgx_capi.c line 222
AMGX ERROR: Error initializing amgx core.
Failed while initializing CUDA runtime in cudaRuntimeGetVersion

Please let me know how I can proceed with solving this issue.

Research direction

The failure is reported at examples/amgx_capi.c line 222; start by reviewing the build and installation instructions alongside the reported driver, nvcc, and CUDA versions. Done means identifying a reproducible cause for the CUDA runtime initialization failure and validating a way to run the example.
