Is it possible to write code for the GPU?

Is there a way to write code For and implement the GPU and its calculation power in ue4++? If so: How and where can I find further information. I know only the bare basics about GPUs (That they can calculate far more at once as long as said calculations are independent), but I have ideas in mind where I would need exactly that.

I know that I am probably pretty oblivious in that regard, but I would be very happy to learn more about the topic. Thanks in advance for any answers

The easiest way is to use the Custom Expressions node:

Otherwise, you can see:
