Thank you !
I’m using 3090Ti
first :
” mpicxx –showme:link ” results : -pthread -Wl,-rpath -Wl,/usr/local/lib -Wl,–enable-new-dtags -L/usr/local/lib -lmpi

second :
” nvcc -V ” results : Cuda compilation tools, release 10.1, V10.1.243

third :
” nvidia-smi ” results : CUDA Version: 12.0

fourth :
” #include <thrust/execution_policy.h> ” add

fifth :
” gpu_only.mk ” result : same error “value c++17 is not defined for std..”

sixth :
The file name in the config folder was changed to config.mk and used.
code
“””
