) Extension proposal to introduce extensions new non-uniform sub-group types which represent subsets of a sub-group (ballot_group, cluster_group, tangle_group, opportunistic_group) and new free functions for creating these. The proposal also introduces new group-related traits and extensions to the SYCL 2020 execution model, specifically the nd-range topology and definitions of control flow and concurrent execution to support these new group types. This extension is related to the root-group proposal #6163.
