It's machine code. CPUs/GPUs don't run C, C++, python, java, etc. They only obey their own instruction set. High-level languages get compiled down to assembly code, then assembled to object files, then linked to executables for that particular processor.

Oh, and Java and python don't get compiled. They get interpreted and run using an engine.
