Hello Jeff Squyres,
I’ m using: openmpi-1.10.2.tar.gz
<https://www.open-mpi.org/software/ompi/v1.10/downloads/openmpi-1.10.2.tar.gz>
The file first.c:
#include "mpi.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
//#include <linux/types.h>
#include
"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/machine/types.h"
//using namespace std;
int main(int argc, char **argv )
{
char text[20];
int myrank, size, sender=0, adressat=1, tag=99;
MPI_Status status;
MPI_Init( & argc, & argv );
MPI_Comm_rank(MPI_COMM_WORLD, & myrank);
MPI_Comm_size(MPI_COMM_WORLD, & size);
printf(" myrank = %d \n",myrank);
printf(" size = %d \n", size);
//printf("Hello, world! "
// "from process %d of %d\n", myrank, size);
if (size > 2 )
{
printf("Beispiel für 2 Tasks \n");
MPI_Finalize();
exit(1);
}
if ( myrank == 0 )
{
strcpy(text, "Hallo zusammen");
MPI_Send(text, strlen(text), MPI_CHAR, adressat, tag, MPI_COMM_WORLD);
}
else
{
MPI_Recv(text, 20, MPI_CHAR, sender, tag, MPI_COMM_WORLD, & status);
printf("Task %d empfing: %s: \n", myrank, text);
}
MPI_Finalize();
return 0;
}
is working, but it is much simpler. On opensuse 13.2 second runs fine.
Test second.c on your machine. I cannot debug it.

Hans-Juergen Greif
