Using c ++ amp to speed up the program in which the MPIR library (GMP) is used. Is this possible?

I want to understand if I can speed up the execution of a loop that works with the MPIR library using the GPU processor and c ++ amp for this?

Here is the code I would like to speed up:

#include <mpirxx.h>
#include <iostream>
#include <cstdlib>
#include <fstream>
#include <string>
#include <ctime>
#include <cstdio>
int main()
{
    srand(time(0));
    using namespace std;


    mpz_class i("0");
    mpz_class l("9999999999999999999999999999");

    for (i = 1; i <= l; i++)
    {
    }

    std::cout << "runtime =" << clock() / 1000.0 << std::endl;
    system("pause");
    return 0;

}

If I run the program on the CPU, it runs extremely slowly, I want to increase the speed of the program using the video card. As far as I understand, I can use almost any modern graphics card with DirectX 11 support, even embedded in the processor, for example intel HD Graphics 510

I think c ++ amp is the most suitable technology for implementing my task if it can interact with the MPIR library.

What should I change in the submitted code to run it on the GPU?
