Whenever you find yourself thinking “I want to start a bunch of processes like this one with different parameters,” xargs probably has your back. When it involves files, find -print0 | xargs -0 is the standard tool.

Or else you put parallelism into your main script itself – the feasibility of that varies. (In your case it would have to be adapted to create output logfiles per some sort of filename template.)
