https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/sum-elements-of-an-array/m-p/766365#M275 I don't think so (at least I didn't find one either), but a simple loop should get auto-vectorized by the compiler. Try option vec-report when compiling to check this.

However, I don't see a simple way to sum the elements of a signed array. Is there a simple way of doing this using an MKL function?
