Users can either install with Conda or build from source.
To run ucx-py's tests, just use pytest:
pytest -vIn order to use TCP add tcp to UCX_TLS and set UCXPY_IFNAME to the network interface you want to use. Some setup examples:
# TCP using "eth0" and CUDA support
export UCX_TLS=tcp,sockcm,cuda_copy,cuda_ipc
export UCX_SOCKADDR_TLS_PRIORITY=sockcm
export UCXPY_IFNAME="eth0"
# InfiniBand using "ib0" and CUDA support
export UCX_TLS=sockcm,cuda_copy,cuda_ipc
export UCX_SOCKADDR_TLS_PRIORITY=sockcm
export UCXPY_IFNAME="ib0"
# TCP using "eno0" and no CUDA support
export UCX_TLS=tcp,sockcm
export UCX_SOCKADDR_TLS_PRIORITY=sockcm
export UCXPY_IFNAME="eno0"
