parallelize

parallelize[func: fn(Int, /) capturing -> None]()

Executes func(0) ... func(N-1) as sub-tasks in parallel, and returns when all are complete. N is chosen to be the number of processors on the system.

Parameters:

  • ​func (fn(Int, /) capturing -> None): The function to invoke.

parallelize[func: fn(Int, /) capturing -> None](num_work_items: Int)

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

CAUTION: Creates and destroys a local runtime! Do not use from kernels!

Parameters:

  • ​func (fn(Int, /) capturing -> None): The function to invoke.

Args:

  • ​num_work_items (Int): Number of parallel tasks.

parallelize[func: fn(Int, /) capturing -> None](num_work_items: Int, num_workers: Int)

Parameters:

  • ​func (fn(Int, /) capturing -> None): The function to invoke.

Args:

  • ​num_work_items (Int): Number of parallel tasks.
  • ​num_workers (Int): The number of workers to use for execution.
