oh my carelessness!
from nccl.
The message you get ("invalid device function") means that one of the GPU cannot execute the compiled code.
Indeed, the GTX760 has a compute capability of 3.0 (https://developer.nvidia.com/cuda-gpus), and the default NVCC_GENCODE in the Makefile only compiles for 3.5 and later.
In the Makefile recompile with :
NVCC_GENCODE="-gencode=arch=compute_30,code=sm_30 -gencode=arch=compute_52,code=sm_52"
then copy build lib to /usr/lib
It work!
from nccl.
You can also set your LD_LIBRARY_PATH instead of installing in /usr/lib :
export LD_LIBRARY_PATH=$PWD/build/lib:$LD_LIBRARY_PATH
./build/test/single/all_reduce_test <size>
