I have CUDA application which I want to use multi GPUs. Firstly I’m testing it on single GPU with setting device always to zero (cudaSetDevice(0)). I use thrust library and create a lot of device_vectors. During creation of them:
thrust::device_vector<std::int64_t> tmp; // class private vector tmp = thrust::device_vector<std::int64_t>(100); // inside constructor of the class
I got an error:
terminate called after throwing an instance of 'thrust::system::system_error' what(): function_attributes(): after cudaFuncGetAttributes: invalid device function
Why it happens? I’ve set device to zero, and all other device_vectors which were created before (in other part of my application) had been created properly. I’ve tried with changing tmp to device_vector pointer and create with ‘new’ keyword but it doesn’t help.
I use GTX950 and build with Compute Capability set to 52 (as should be).
