With MPI programs, do all processes get data from user input?

Question

What I'm asking is if I have something like this:

int main(int argc, char *argv[]) //<---input from command line
{

Do I need to use MPI_Bcast in order to send that data to all of the processes, or do all of the processes get the command line input data anyway?

Answer 1

If you use MPI_Init(&argc,&argv) this solves you problem :)

No need to BCast anything ;)
