For a sequential ordering, i.e.

1:1 mapping of steps per species onto traversals, it makes no real difference how we order the progress through the individual steps. So I just concatenate the steps per species.

Actual translation of one step per particle species onto a task graph construction.

We basically forward to exaparty.api.graphcompiler.TaskGraph.translate_one_step_of_species_into_mesh_traversal() but we set the flag synchronise_task_graph_after_each_mesh_sweep() to false. This does not mean that the arising task graph is bare of all synchronisation. It just means that we don't immediately synchronise after each step.

All the wrappers have implicitly built in some synchronisation: A vertex issues a task with a number. If this number is already tied to an existing task, this creates an in-out dependency. However, we have three types of task numbers per species:

• touch vertex first task numbers
• touch cell first task numbers
• touch vertex last task numbers

Each observer will create vertex first-vertex first-cell-vertex last chains of tasks with an arbitrary number of first and last instances. The important thing to keep things correct therefore is that we establish vertex last-vertex first relations here which ensure that one chain does not mangle into the chain of the predecessor.

This is the added thing here. Global syncs will automatically be added where they are necessary (cmp. translate_one_step_of_species_into_mesh_traversal() and the variable synchronise_after_each_mesh_traversal therein).

• wrapper alles first
• nix in touch cell last
