How does the task structure look like here? It looks like the tasks
execute concurrently and increment a counter on start/finish -
atomically, as you say. What I mean with structure are for example
hierarchical (e.g., tree-like) groupings of tasks.

I haven't looked at it in detail, but Oliver Kowalke's task and fiber
implementation in the Boost vault look like a good starting point. From
the documentation, it seems there is some support for structuring tasks
via sub-tasks. The libraries support atomic operations via
Boost.Atomic.
