I knew there is a collectives library named UCC. But when I saw UCX doc I found it said "Collectives: This subset of interfaces defines group communication and synchronization operations." in design.md.

Hi @MoFHeka,
UCX has UCG as a sub-repo that has some collective APIs, and it looks like it hasn't been maintained in the past 4 years,
Using UCC / OpenMPI for collective operations would probably yield better results, depending on what you need.

Sadly, UCG has been unable to be compiled for latest UCX.
