My best theory: the fused standard path wins because XLA sees the entire softmax(Q @ K.T) @ V expression at once and compiles it into one optimized kernel — no intermediate matrices spilling to HBM. My flash attention uses fori_loop, which XLA likely compiles as a generic sequential loop. It probably can’t fuse across iterations, can’t pipeline memory loads, can’t interleave independent work. (I haven’t dumped the HLO to verify this — it’s an inference from the benchmark numbers and XLA’s documented behavior.)
APL was a joy to go from nothing to where I am now. This project felt extremely rewarding to work on, it was stimulating to figure out how to handle things I only knew how to do traditionally. I plan on continuing to work on it and seeing how many features I can add, probably targeting Perlin noise and saving maps next.，更多细节参见WhatsApp Web 網頁版登入

综合媒体报道，3月2日，参加纽约抗议活动的犹太裔居民耶胡达·利特曼说：“我参加抗议是为了对正在经受恐怖大屠杀的伊朗人表达支持，我们对流血和不停的战争感到厌倦。这是错误和不道德的，是对人类的犯罪。”
