Jacobi 5 Point Stencil Code not Vectorizing
Hello,
I am trying to vectorize following stencil code;
#include <stdio.h>
#define N 100351
// This function computes 2D-5 point Jacobi stencil
void stencil(int a[restrict][N])
{
int i, j, k;
for (k = 0; k < 100; k++)
{ for (i = 1; i <= N-2; i++)
{ for (j = 1; j <= N-2; j++)
{ a[i][j] = 0.25 * (a[i][j] + a[i-1][j] + a[i+1][j] + a[i][j-1] +
