When you are compiling CUDA code for Nvidia GPUs it’s important to know which is the Compute Capability of the GPU that you are going to use. How many times you got the error
nvcc fatal : Unsupported gpu architecture ‘compute_XX’
and you do not know how to correctly solve it.
The solution is relatively simple, you must add the correct FLAG to “nvcc” call:
-gencode arch=compute_XX,code=[sm_XX,compute_XX]
where “XX” is the Compute Capability of the Nvidia GPU board that you are going to use.
Now you need to know the correct value to replace “XX“, Nvidia helps us with the useful “CUDA GPUs” webpage.
For example, if your GPU is an Nvidia Titan Xp, you know that it is a “GeForce product“, you search for it in the right table and you find that its Compute Capability is 6.1, so the correct FLAG to use in the compiler is
-gencode arch=compute_61,code=[sm_61,compute_61]
if you are instead an embedded developer and you are a lucky owner of an Nvidia Jetson TX2, you must search in “TEGRA/Jetson products” and you will find that the Compute Capability of the TX2 is 6.2, so you need to use this configuration:
-gencode arch=compute_62,code=[sm_62,compute_62]
straightforward!
If you are compiling software that will run on different machines and you do not know exactly which GPU is installed on them, you can generate an application that supports more than one Nvidia GPU technology:
ARCH= -gencode arch=compute_30,code=[sm_30,compute_30] \
-gencode arch=compute_35,code=[sm_35,compute_35] \
-gencode arch=compute_50,code=[sm_50,compute_50] \
-gencode arch=compute_52,code=[sm_52,compute_52] \
-gencode arch=compute_61,code=[sm_61,compute_61]
