迭代器是编译期做的数组越界检查，循环是运行期做的检查有额外性能损失没觉得有可能效率比 loop ｛ .....

// Currently, LLVM is unable to unroll the loop below. match exp { 0 => return 1, 1 => return base, 2 => return base.wrapping_mul(base), 3 => { let squared = base.wrapping_mul(base); return squared.wrapping_mul(base); } 4 => { let squared = base.wrapping_mul(base); ret...
合作的知识星球打开引擎盖。 春节假期在做crabml的 CPU 推理优化,在做了一些优化后,推理一个 3B 的 Q8_0 模型的性能从 7 tok/s 优化到了 12 tok/s,仍比跑到 14 tok/s 的 ggml 慢一些,不过先记录一下做优化的过程,感觉追平性能还是有戏的。
where it is in the sequence. In other words, this codeconsumes, or uses up, the iterator. Each call tonexteats up an item from the iterator. We didn’t need to makev1_itermutable when we used aforloop because the loop took ownership ofv1_iterand made it mutable behind the scenes....

This adds bpfel-unknown-none and bpfeb-unknown-none, two new no_std targets that generate little and big endian BPF. The approach taken is very similar to the cuda target, where TargetOptions::obj_...
