I'm studying a bit of MPI, and decided to do a test by making a program that calls objects, eg main.c -> main program, function.c -> any function

function.c that will only use the MPI. compiling I as follows. gcc-c main.c to create main.o mpicc-c to create function.c function.o, of course I create the file function.h too.

I compile with mpicc-o program main.o function.o

here main.c

#include <stdio.h> #include "function.h" void main(int argc, char *argv[]) { printf("Hello\n"); function(); printf("Bye\n"); } 

just function has the MPI code, but when i'm running the program mpiexe -np 2 program i get

Hello Hello ----- function job here ----- Bye Bye 

but I wanted it to be

Hello ------ function job ----- Bye 

what can i do?

sorry my bad english :)
