sync_parallelize

sync_parallelize[origins: OriginSet, //, func: def(Int) raises capturing -> None](num_work_items: Int, ctx: Optional[DeviceContext] = None)

Executes func(0) ... func(num_work_items-1) as parallel sub-tasks, and returns when all are complete.

TODO: Currently exceptions raised by func will cause a trap rather than be propagated back to the caller.

Parameters:

  • ​origins (OriginSet): The capture origins.
  • ​func (def(Int) raises capturing -> None): The function to invoke.

Args:

  • ​num_work_items (Int): Number of parallel tasks.
  • ​ctx (Optional): Optional CPU DeviceContext to execute the tasks on.

sync_parallelize[FuncType: def(Int) register_passable -> None](func: FuncType, num_work_items: Int, ctx: Optional[DeviceContext] = None)

Executes func(0) ... func(num_work_items-1) as parallel sub-tasks, and returns when all are complete.

Parameters:

  • ​FuncType (def(Int) register_passable -> None): The body function type.

Args:

  • ​func (FuncType): The closure carrying the captured state of the body function.
  • ​num_work_items (Int): Number of parallel tasks.
  • ​ctx (Optional): The CPU DeviceContext to enqueue the work on.
