Purpose:
Multiply the low unsigned 32-bit integers from each packed 64-bit element in "a" and "b", and store the unsigned 64-bit results in "dst".
Result:
__m512i
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512i a = _mm512_set_epi32(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16);
__m512i b = _mm512_set_epi32(2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17);
__m512i r = _mm512_mul_epu32(a, b);
unsigned long long* res = (unsigned long long*)&r;
for (int i = 0; i < 8; ++i)
printf("%llu ", res[i]);
return 0;
