<h3 id="Exercise-2">Exercise 2<a class="anchor-link" href="#Exercise-2"></a></h3><p>In the parallel implementation of the Jacobi method, we assumed that the method runs for a given number of iterations. In function, <code>jacobi_with_tol</code> at the beginning of the notebook shows how the Jacobi iterations can be stopped when the difference between iterations is small. Implement a parallel version of this function. Start with the in Exercise 1 and add the stopping criterion implemented in <code>jacobi_with_tol</code>. Use a text editor and the Julia REPL. Do not try to implement the code in a notebook.</p>
