Eric my last experiments were with it on version 6.so.. check if you have
the original driver installed correctly not the RPM version of it.

Hey all,

I’m relatively new to Linux generally and SL in particular. I’m running
SL7, and have run aground trying to follow the setup instructions at
http://developer.download.nvidia.com/compute/cuda/8.0/
secure/Prod2/docs/sidebar/CUDA_Installation_Guide_Linux.
pdf?autho=1492553753_fc0d9c1b985f0ba78200964ccf8f1d

I’ve been following the RHEL/CentOS instructions, as my understanding is
that SL7 should just be a drop in for those. Things seem to go well until
the “Verify the Installation” step at 6.2.2 in the document.

Verifying the Driver Version with $cat /proc/driver/nvidia/version returns
‘No such file or directory’

The examples compile fine in 6.2.2.3, but when you run the deviceQuery
binary, rather than finding the Quadro K620 sitting in the machine at the
moment, it returns:

./deviceQuery Starting…

CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 30
-> unknown error
Result = FAIL

That’s where I stopped, as it appears the GPU isn’t talking nicely with
CUDA. lspci can see the GPU - is this just a driver issue? If so, is sudo
yum install cuda-drivers likely the easiest fix?

Thanks in advance for the help,

Eric
