about parallel execution

[Yixun Liu]

Hi,
I am a new user of PETSC. I want to know how to execute of the PETSC application.
For example, my code are like below,

PETSCInitialize();
code1;
code2;
.....
PETSCFinalize();

Does PETSC copy the above codes, assuming there n processors, to each processor? Will code1 be execute on each processor?

Best regards,

Yixun
