HI, this is probably something simple. I did install the Nvidia driver.
NVRM version: NVIDIA UNIX x86_64 Kernel Module 390.77 Tue Jul 10 18:28:52 PDT 2018
GCC version: gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)
The toolkit is installed and I did a make to compile all of the examples.
nvcc: NVIDIA ® Cuda compiler driver
Copyright © 2005-2018 NVIDIA Corporation
Built on Tue_Jun_12_23:07:04_CDT_2018
Cuda compilation tools, release 9.2, V9.2.148
However, when I go to /usr/local/cuda-9.2/samples/bin/x86_64/linux/release
and attempt to run any of the samples, I get, for example with “clock”
CUDA Clock sample
CUDA error at …/…/common/inc/helper_cuda.h:1147 code=30(cudaErrorUnknown) “cudaGetDeviceCount(&device_count)”
I feel that this is something simple like a path variable or something.
