Hi dear developer,
I noticed in ucx_init_context, there is a veriable named NCCL_UCX_CUDA_DISABLE, which will filter the UCX_TLS=cuda
Cannot catch the point, why here filter the UCX_TLS=cuda?
Is it mean the UCX_TLS=cuda only work intra node? but if uses set UCX_TLS=cuda mannually, NCCL run the UCX plugin will cause an error.
Could you please give me somg hints?
Thanks a lot!
