I am learning how to program in opencl and I made a simple program that simply takes an array and adds 1 to every element. I want to run it many times (this is just so that i can benchmark how it does against my cpu, I understand it is a dumb application).
I feel like the way I am doing it right...
Im still a noob in algorithms and data structures and this my attempt to check if two string are isomprhic.

How can I do this in a more performant way? I'm concerned that throwing the data in a queue like this is defeating the purpose of yield from the open() and also how about handling the shared reference to file handle?

The program needs to only keep directories that have at least 1 .osu (.ini like) file with certain restrictions in them.
It also needs to delete duplicate .osu files.
But since duplicate files are only in duplicate directories (never in the same directory), we can also just delete all but one dir...

(Besides trivialities i.e. inserting constants, not lazy importing). Specifically, I'd like to speed up fastMinPayout if there is a way to do it without using log.
