Cannot generate the half2 codes

[xinyi-li7]

I just followed the README but generated the following error when trying the vectorAdd.cu test

$user:~/cuda-half2$ ./detect_vars.sh test/vectorAdd.cu
warning: Unknown CUDA version. cuda.h: CUDA_VERSION=11070. Assuming the latest supported version 10.1 [-Wunknown-cuda-version]
error: cannot find libdevice for sm_20. Provide path to different CUDA installation via --cuda-path, or pass -nocudalib to build without linking with libdevice.
error: GPU arch sm_20 is supported by CUDA versions between 7.0 and 8.0 (inclusive), but installation at /usr/local/cuda-11.7 is 11.0. Use --cuda-path to specify a different CUDA install, pass a different GPU arch with --cuda-gpu-arch, or pass --no-cuda-version-check.

I cannot find a way to change the architecture of GPU. Is there any way to solve this issue?

Hi, thanks for trying out. This repo is not maintained for a long time and hence cannot run with newer compilers or architectures.
