WebFeb 12, 2024 · It is not technically legal to use SIMD on most floating-point loops, including the inner product in matrix multiplication, because rounding errors are not commutative. C compilers don't vectorize such loops either unless you pass the -ffast-math flag. I'm sure the JIT compiler of JVM has a similar option.

This is the first time I'm answering my own question but it seems appropriate. Based on hirschhornsalz answer for prefix sum on 16 bytes simd-prefix-sum-on-intel-cpu I have come up with a solution for using SIMD on the first pass for 4, 8, and 16 32-bit words. The general theory goes as follows.
