But now I got tim_var[1000][6]

Would you please check ?

float * tim_var[1000];

// clean-up
for (i=0;i<1000;i++)
{
  delete tim_var[i];
}

float **tim_va;

tim_va = new float*[1000];

for (int ix = 0; ix < 1000; ix++)
{
    tim_va[ix] = new float[6];

    for (int jy = 0; jy < 6; jy++)
        tim_va[ix][jy] = 0.0;
}

for (int ix = 0; ix < 1000; ix++)
    delete [] tim_va[ix];

delete [] tim_va;

The code you put are the same as I reported before. I can not see any difference.

#pragma omp parallel
{
    if(omp_get_thread_num() > 3) 
    {
        #pragma omp single    // May not be accessed by all threads
        x++;
    }
}
