although from your language you want want to run multiple different tasks in parallel which happens automagically My example is running a task multiple times in parallel operating on a list of items to be operated in parallel

Rob Fowler · Answer

just a ps If you are wanting more threads you can increase them flow executor = LocalDaskExecutor workers=30 I find processes more stable for large numbers of workers but YMMV
