Hi,

I've a strange problem on my server. I've installed a GPU (Geforce 950) and want to run some CUDA tests.

My server is running the hardened/linux/amd64/no-multilib profile and has the linux-4.1.7-hardened-r1 kernel. The monitor is connected direcly to the onboard graphics card.

I've installed the following packages:

Quote:
dev-util/nvidia-cuda-sdk-7.5.18
dev-util/nvidia-cuda-toolkit-7.5.18-r2
x11-drivers/nvidia-drivers-361.28


(been compiled without X support (USE="-X"))

The module is loaded:

Code:
Module                  Size  Used by
nvidia_uvm            587555  0
nvidia               9958777  1 nvidia_uvm
x86_pkg_temp_thermal     4088  0


and when I try to run deviceQuery:

Quote:
./deviceQuery
./deviceQuery Starting...

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

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL


Is there anything more I have to do to make CUDA works ? I've the exact same versions on my PC and I haven't had any issues whatsoever.

Thanks

I tried with the standard kernel:

Code:
uname -a
Linux hel.asgard 4.1.15-gentoo-r1 #1 SMP Tue May 3 21:32:34 CEST 2016 x86_64 Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz GenuineIntel GNU/Linux


With the same result :(

Could this be an hardware issue ?

Thanks

I've been able to solve my problem by getting rid of the hardened profile:


  1. Uninstalled all nvidia packages
  2. switched to a default profile (instead of hardened)
  3. reemerged everything (empty tree)
  4. installed the nvidia packages
  5. rebooted
  6. everything works fine
