Amazing dissertation by Aaron Wen-yao Hsu, demonstrating a novel memory layout for ASTs and advocating for bottom-up traversal patterns. The fact that the compiler is just 17 lines of APL (which I can’t read in the slightest) is even cooler.

Interesting study of vectorizing the tokenization of a complex language.

I’ve thought about vectorized sorting for a while, but I didn’t know that bitonic sorts can be implemented efficiently on SIMD registers. This is an interesting approach.
