3.4.4. Derefine event sequence

• Call list_t%remove_remove_and_reset() to

  • set bits%remove, which hides the task in check_ready() (task and nbor)

  • remove the task from the task list (it will remain in garbage bin while needed)

  • use the existing nbor list to set bits%init_nbors on nbors

  • now that the task is removed, call check_nbors() to see if nbors have become ready

  • move the task to the garbage bin

  • when the task is no longer needed (no longer is a member of an nbor list) the task is deallocated and deleted by list_t%garbage_remove()

• In task_mesg_t%unpack()

  • detect bits%remove and call list_t%remove_remove_and_reset()

This is identical to what is done on the owner rank, and is taken care of by the list_t%remove_and_reset() procedure.
