What are some practical problems that parallel computing, f#, and GPU-parallel processing might solve

Question

Recently WiFi encryption was brute forced by using the parellel processing power of the modern GPU. What other real-life problems do you think will benefit from similar techniques?

Answer 1

Image processing which is just fancier signal processing which is massively parallel math.

given that, perhaps face recognition, voice recognition, video decode/encode, audio decode/encode, encryption/decryption
