> We now also have explicit SIMD vectorisation.. So say on an AVX512 enabled architecture you can compute the dot product of two vectors I wonder will it be good? Computing dot product efficiently is harder than it seems, example: https://stackoverflow.com/a/59495197/126995 https://stackoverflow.com/a/59495197/126995 Eigen usually does stuff like that rather well.
