I've been sitting here working for the past 48 hours and I'm fighting a stupid bug in some mpi code I'm working on
How do I broadcast a char string to my slave mpi processes? And how do I receive that char string and print it out on my slave mpi process.
This is what I have in my code(some things have been removed)
#define MASTER_RANK 0
mystring = "some test";
MPI_Bcast(&mystring, sizeof(basedir), MPI_CHAR, MASTER_RANK, MPI_COMM_WORLD);
in my slave process code I have this
printf("my string I received: %s", mystring);
Am I doing something wrong? Or if someone has some sample code they can point me to on how to send a string to a slave mpi process and have that slave mpi process print out the string..that would be even better. That way..I relearn MPI basics 101
