Select compute device with CUDA backend

[mmoeller]

Dear all,

selecting the device with the OpenCL backend can be done via

viennacl::ocl::set_context_device_type(n, viennacl::ocl::gpu_tag());

Is there a similar thing for the CUDA backend?

Thanks and best regards,
Matthias

Hi Matthias,
no, CUDA only works for GPUs. If you want to select a particular CUDA device, use cudaSetDevice() directly (at the very beginning of your application).
Best regards,
