Question

Modify Algorithms so that they work for any number of processes,not just the powers of 2.

1. procedure ONE_TO_ALL_BC(d, my_id, X)
2. begin
3. mask := 2d - 1; /* Set all d bits of mask to 1 */
4. for i := d - 1 downto 0 do /* Outer loop */
5. mask := mask XOR 2i; /* Set bit i of mask to 0 */
6. if (my_id AND mask) = 0 then /* If lower i bits of my_id are 0 */
7. if (my_id AND 2i) = 0 then
8. msg_destination := my_id XOR 2i;
9. send X to msg_destination;
10. else
11. msg_source := my_id XOR 2i;
12. receive X from msg_source;
13. endelse;
14. endif;
15. endfor;
16. end ONE_TO_ALL_BC
