Following Mathieu Westphal’s instructions I started using ParaView 5.7 in order to use NVIDIA IndeX. I used an OpenFOAM case and got the following messages:
nvindex: 1.0 INDEX main warn : Failed to open '/proc/driver/nvidia/version'. Please verify that the NVIDIA driver is installed properly. nvindex: 1.0 INDEX main error: Failed to query the number of CUDA devices (cudaGetDeviceCount): no CUDA-capable device is detected. nvindex: 1.0 INDEX main error: Could not find any valid CUDA devices, aborting. nvindex: 1.0 PVPLN main error: Start of the NVIDIA IndeX library failed. nvindex: 1.0 PVPLN main error: Failed to start the NVIDIA IndeX library: 1. nvindex: 0.1 GPU rend warn : It appears that the "nvidia" kernel module is not loaded. nvindex: 0.1 GPU rend warn : It appears that there are no "nvidia" device nodes. This configuration is unlikely to work at all. Verify that your runlevel is sufficient and "nvidia" device nodes are present, e.g., /dev/nvidia0. nvindex: 0.1 CUDA rend warn : CUDA module initialization failed. nvindex: 0.1 CUDA rend warn : cudaRuntimeGetVersion returned with error 'no CUDA-capable device is detected'
I want to know if they are major errors or I can continue working.
