Current exascale computers use non-Infiniband networks, such as HPE Slingshot and (soon) Ultra Ethernet. Both provide application code interfaces using libfabric, and cannot use UCX. On these machines, the only way to use Dask is to transport data over TCP, which is slow.

It would be great if Dask would support libfabric as a transport layer!
