cudaGetDeviceCount returned 35

Unfortunately for any machine installed by now the setup is now as
described,
and works.
There is one machine were this setup was not updated and YES I have the
same result as you :
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
On this machine the driver is rather old:
dpkg -l |grep nvidia
ii nvidia-331 340.96-0ubuntu0.14.04.1 amd64
Transitional package for nvidia-331
ii nvidia-340 340.96-0ubuntu0.14.04.1 amd64
NVIDIA binary driver - version 340.96
ii nvidia-340-uvm 340.96-0ubuntu0.14.04.1
amd64 Transitional package for nvidia-340
ii nvidia-libopencl1-340
340.96-0ubuntu0.14.04.1 amd64 NVIDIA OpenCL
Driver and ICD Loader library
ii nvidia-opencl-icd-340
340.96-0ubuntu0.14.04.1 amd64 NVIDIA OpenCL ICD
ii nvidia-prime 0.6.2
amd64 Tools to enable NVIDIA's Prime
ii nvidia-settings 331.20-0ubuntu8
amd64 Tool for configuring the NVIDIA graphics driver
But I wrote my "tutorial" since the latest package available in Ubuntu
is "nvidia-352 - NVIDIA binary driver - version 352.63",
and apparently cuda expects 352.79, the minor revision in the driver is
sufficient to have CUDA + GROMACS failing,
and apparently this is from CUDA :-)
You have the answer: use the exact driver of the CUDA runtime and
nothing else ...
Best,
Stéphane
