KOKKOS-CUDA runtime error

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
Copyright © 2005-2019 NVIDIA Corporation
Built on Wed_Oct_23_19:24:38_PDT_2019
Cuda compilation tools, release 10.2, V10.2.89

Your suggestions and advices are greatly appreciated.

Frank

you need to contact your system administrators about this.

the driver that this error is referring to refers to the kernel level driver and the corresponding library.

please have a look at: https://docs.nvidia.com/deploy/cuda-compatibility/index.html
there is some way to include forward compatibility, but that depends on how cuda is deployed on your system.

this is not a LAMMPS issue.

Axel.
