Dear developers and users,
I compiled KOKKOS-CUDA successfully for LAMMPS 3Mar20 version on a HPE SGI 8600 machine with CUDA 10.2, gcc 7.3.0 and mpt 2.20 successfully
When I tested run the executable, I had runtime errors:
……
terminate called after throwing an instance of ‘std::runtime_error’
what(): cudaGetDeviceCount( & m_cudaDevCount ) error( cudaErrorInsufficientDriver): CUDA driver version is insufficient for CUDA runtime version /app/lammps/lammps-3Mar20_kokkos/lib/kokkos/core/src/Cuda/Kokkos_Cuda_Instance.cpp:204
Traceback functionality not available
…….
By checking CUDA driver version, I have:
nvcc: NVIDIA ® Cuda compiler driver

Cuda compilation tools, release 10.2, V10.2.89
Your suggestions and advices are greatly appreciated.
