{lib}[GCCcore/11.3.0] UCC v1.0.0

[bartoldeman]

(created using eb --new-pr)

[bartoldeman]

UCC is newly supported by Open MPI 4.1.4

Note that UCC like UCX can optionally depend on CUDA (and NCCL for UCC only), and uses dynamically loaded components for that.

But fortunately unlike for UCX no special patch is needed, since UCC_COMPONENT_PATH is sufficient and glob(3) does the rest.

@boegelbot please test @ generoso

so we'll make a UCC-CUDA much like UCX-CUDA later (once we decide on CUDA version)?

yes exactly!
