Improvement

How would you describe the priority of this feature request

Medium

Please provide a clear description of problem this feature solves

Cugraph dask algorithms like wcc are used in downstream libraries like NeMo-Curator and require intializing comms with something like cugraph.dask.comms.comms.initialize(p2p=True).

Setting p2p=False is currently unsupported and p2p=True creates UCX endpoints to establish connections to workers even when working with a TCP based dask cluster.

Many systems & clusters have varying network topologies and require different UCX specific configurations to be set up correctly for the setup to work as expected & therefor p2p=True fails in many cluster unless the right UCX configurations are set.

It would improve usability if there was an option to run mnmg algorithms on a TCP cluster without any UCX config or endpoint creation.

Describe your ideal solution

cugraph.dask.comms.comms.initialize(p2p=False) # False works, no ucx created

# Proceed with mnmg algorithms.

Describe any alternatives you have considered
