I'm trying to write code by VNNI
There is a data type - __m512i
which I think is mapping to registers on CPU.
I'd like to locate an array of registers
Here is the code
#include <immintrin.h>
int main()
{
const int size = 5;
__m512i zero[size];
for(int i=0; i<size; i++)
{
zero = _mm512_setzero_si512();
}
return 0;
}
It works.
But when I try dynamic allocate memory
It doesn't work
#include <immintrin.h>
int main()
{
const int size = 5;
__m512i *zero = new __m512i[size];
for(int i=0; i<size; i++)
{
zero = _mm512_setzero_si512();
}
delete [] zero;
return 0;
}
Is there any way to create registers dynamically?
Lot of thanks
