Functions
void	Initialize (int argc, char *argv[], Data *data, Input *input, Grid *grid, Cmd_Line *cmd_line)

Detailed Description

Initialize() performs a number of initialization tasks before starting the main computation loop.
More precisely, it completes the following sequence of steps:

• parse command line options
• runtime initialization (i.e. pluto.ini)
• parallel domain decomposition
• grid generation
• memory allocation
• initial conditions
• set output attributes

The function GetDecompMode() sets the parallel domain decomposition mode which can be equal to

• AL_AUTO_DECOMP default;
• AL_USER_DECOMP if the -dec n1 [n2] [n3] command line argument has been given; In this case only, procs[] contains the number of processors in the three directions;
• AL_MPI_DECOMP [todo]
