Dear all,
I am not sure if I landed in the right forum category, please redirect me somewhere else if needed. I would like to use Nvidia Fortran compiler with OpenACC for development and profiling of my programs. I have downloaded Nvidia HPC-SDK and installed it on Ubuntu 18.04 workstation.
Command:
nvidia-smi
gives me this output:
+-----------------------------------------------------------------------------+

However, if I run the command:
nvaccelinfo -v
I get the following output:
CUDA Driver Version: 10000
NVRM version: NVIDIA UNIX x86_64 Kernel Module 410.66 Wed Oct 10 12:01:53 CDT 2018
could not initialize CUDA runtime, error code=999
No accelerators found.
Check the permissions on your CUDA device
I am doing all of this as a root, and I do have the /dev/nvidia* files with proper permissions:
crw-rw-rw- 1 root root 195, 0 Jul 13 16:18 /dev/nvidia0
crw-rw-rw- 1 root root 195, 255 Jul 13 16:18 /dev/nvidiactl
crw-rw-rw- 1 root root 195, 254 Jul 13 16:18 /dev/nvidia-modeset
crw-rw-rw- 1 root root 511, 0 Jul 13 16:57 /dev/nvidia-uvm
crw-rw-rw- 1 root root 511, 1 Jul 13 16:57 /dev/nvidia-uvm-tools
I do not, however, have the file:
/usr/lib64/libcuda.so
which, although worrisome, is probably a separate issue.
The card I have on my system Ge-Force RTX 2070. According to this page: https://developer.nvidia.com/cuda-gpus#compute it should be possible to use it for CUDA computing.
I am pretty new to the whole thing, and am baffled. I spent some time googling for potential solution but it was to no avail. Any advice would be appreciated.
Thanks
