plural int a, b;

• xnetW[1].a = a; left shift

  All active processors simultaneously transfer the values of their local variables $a$ to their left neighbors.

• a = xnetE[1].a; left shift

  Each active processor receives the new value for its local variable $a$ from the local variable $a$ of its right neighbor.

• a = a+xnetE[1].b;

  Each active processor increments its local variable $a$ by the value of the local variable $b$ of its right neighbor.
