Hello. I have a project that is meant to be compiled using NVCC. Could you tell me what are the flag parameters for the DRIVE AGX Xavier platform? (i mean something like for example. -gencode arch=sm_70,code=sm_70).
Thanks in advance!

Dear @david.nevezi-strango,
You can check the compute capability using CUDA deviceQuery sample on target. For iGPU, use -gencode arch=compute_72,code=sm_72
Similarly for dGPU, if it is volta. use sm_70, if it is turing, use sm_75

I ll post the output of deviceQuery. Since I am new to Cuda, could you help me understand this output. If i understood right, i have an iGPU. in that case, how could have i find out if i would have had a volta or turing GPU?

Result = PASS

Dear @david.nevezi-strango,
deviceQuery sample shows the available GPUs on machine. Your board seems to be DRIVE AGX Xavier. So it does not have dGPU. The CUDA capability parameter denotes the GPU architecture. For volta iGPU it is 7.2, For turing dGPU it would be 7.5

Okay, thank you very much!
