CMAKE_CUDA_ARCHITECTURES

Open adayton1 opened this issue 2 years ago • 1 comments

It looks like RAJA is using custom variables for setting the CUDA architecture (CUDA_ARCH and CUDA_CODE, see https://github.com/LLNL/RAJA/blob/develop/CMakeLists.txt#L114). In CMake 3.18, a new variable called CMAKE_CUDA_ARCHITECTURES is provided so that CMAKE_CUDA_FLAGS does not have to be modified directly.

It looks like this is going to be important with newer cmake versions, I tried using 3.21.1 with our scripts on rzansel and got a warning for every target that CUDA_ARCHITECTURES is empty.

This was done in the latest release.
