Figure: Choleski Decomposition
In this section we give two example programs to show the new
language features. The first example is Choleski decomposition, see
figure 
.
Here, remap is used to broadcast one updated column to each
process. The function idx gets the global index of location
m relative to the parent range x.
The second example is Jacobi iteration, see figure ,
In the displayed code there is only one iteration, but it demonstrates
how to define range references with ghost areas, to use
the writeHalo function, and use of shifted locations
as subscripts.
