Hi, I am trying to offload to my GPUs. I have GTX1060 6GB with compute capability of 6.1.
I followed the instructions given in https://hpc-wiki.info/hpc/Building_LLVM/Clang_with_OpenMP_Offloading_to_NVIDIA_GPUs Then I compiled my helloworld program using the following environment variables: CFLAGS="-fopenmp -fopenmp-targets=nvptx64-sm_61 -pthread -I /usr/lib/gcc/x86_64-linux-gnu/9/include -O2 --libomptarget-nvptx-path=$CLANG_HOME/lib --cuda-gpu-arch=sm_61" LD_LIBRARY_PATH=$CLANG_HOME/lib:$LD_LIBRARY_PATH CC=clang my helloworld program simply printfs omp_get_num_devices() after #including <omp.h> it compiles fine; but when i run it i get the number of devices as 0. Does someone have any idea? Thanks much, Mani
