[Mpi-forum] I can not make MPI recognizes a dual core

Hello. I am writing my first program in MPI. I write the sentences:
int id;
MPI_Comm_rank (MPI_COMM_WORLD, & id);
if (id == 0)
/ * Master task * /
/ * Worker task * /
And I write other sentences. The issue is that it does not recognize a
DualCore processor, and takes the machine as it only has one
processor, indeed, never enters the else.
I would appreciate very much any help.
