Hi Richard, Thank you so much for the reply!
You're absolutely right about using CPU threads. I’m just really curious about whether GPU acceleration could somehow be explored for compilation, even if it’s not traditionally well-suited. I know it might not be practical, but I wanted to understand *why* it’s considered inefficient and learn through experimentation. I’m still a student and just starting to explore compilers more seriously, so any resources you could recommend to help me learn — especially from the basics — would be incredibly helpful. Thanks again for taking the time to respond!
