Hello, please, I am trying to write an MPI program where P0 send messages to the even processes and P1 sends to the odd processes. P0 cannot send to itself as even and neither can P1 send to itself as odd. It must start from P2. Thank you.

Hello. That is the code given. At the bottom, after the return 0 is the closed curly braces. Nothing else was given in the code. It works when i run it, I'm just not getting the correct values.

But if I may ask, what do you think is missing. Thank you.

#include #include /* For strlen */ #include /* For MPI functions, etc */ const int MAX_STRING = 100; int main(void) { char greeting[MAX_STRING]; int comm_sz; /* Number of processes */ int my_rank; /* My process rank */ MPI_Init(NULL, NULL); MPI_Comm_size(MPI_COMM_WORLD, &comm_sz); MPI_Comm_rank (MPI_COMM_WORLD, &my_rank); if (my_rank != 0) sprintf (greeting, "Greetings from process %d of %d! ", my_rank, comm_sz); MPI_Send (greeting, strlen( greeting)+1, MPI_CHAR, 0, 0, MPI_COMM_WORLD); } else { printf ("Greetings from process $d of %d ", my_rank, comm_sz); int g; for (g = 1; g /* For strlen */ #include /* For MPI functions, etc */ const int MAX_STRING = 100; int main(void) { char greeting[MAX_STRING]; int comm_sz; /* Number of processes */ int my_rank; /* My process rank */ MPI_Init(NULL, NULL); MPI_Comm_size(MPI_COMM_WORLD, &comm_sz); MPI_Comm_rank (MPI_COMM_WORLD, &my_rank); if (my_rank != 0) { sprintf (greeting, "Greetings from process %d of %d! ", my_rank, comm_sz); MPI_Send( greeting, strlen(greeting)+1, MPI_CHAR, 0, 0, MPI_COMM_WORLD); } else { printf("Greetings from process $d of %d ", my_rank, comm_sz); int ; for (g = 1; g
