[MPICH] mpich2 & rand()

[Andras Joo]

Hi,

I've encountered a problem regarding the random number generator inside 
mpich. Please consider the following code segment

//...init mpi
srand(time(0));
cout << rand() << endl;
cout.flush();
//...finalize mpi

Now each time I run the program with
$ mpirun -n nr_proc my_prog
I got a sequence of nr_proc elements, with the same value!
It is crucial for me to get different values for the different processes.
Can anyone help me out with this, please?

Thank you,
Regards,
Andras
