speed up the simulation with more "cores" in anuga

[mikilterribile]

I have tried to speed up the simulation with Anuga using "domain = distribute(domain, verbose=True)" at the beginning and " domain.sww_merge(delete_old=True)" at the end but it looks like the speed is the same and that anuga doesn't use multiple cores. I use a normal private laptop, with 8 cores available. Thanks in advance, Best regards,
