The case for cpu parallel computing

[dili5]

Hello, Professor：

 Any case study on cpu parallel computing please? Or how it is used.

@dili5 We have examples of parallel code in the anuga_core/examples/parallel directory.

For instance to run on 3 cores use:

mpiexec -np 3 python -u  run_parallel_tsunami.py

The -u helps to flush the print buffers and so makes for cleaner output during the simulation.

Note that in a parallel script, you first create your standard domain on process 0, and then distribute that sequential domain to a parallel domain which has instances on all the processes.
