Exactly the hint that I needed -- thanks Gilles!

Andy,
it looks like some MPI libraries are being mixed in your environment
from the test/datatype directory, what if you
ldd .libs/lt-external32
does it resolve the the libmpi.so you expect ?
Cheers,

Hi,
your program hangs because rank 0 does not call MPI_Bcast()
generally speaking, when using collective operations (such as MPI_Bcast),
all tasks of the communicators must invoke the collective operation, and
with "matching" arguments.
in the case of MPI_Bcast(), the root value must be the sam
When you call mpi_bcast all the processors should be calledin you code
you are calling mpi_bcast in all the roots expect root. Try keeping
mpi_bcast out of if condition.

Greetings!
I include a static header file utils.h with a function linspace. My main.cpp
file is as follows:
#include
#include
#include
using namespace std;
int main(int argc, const char * argv[]) {
float start = 0., end = 1.;
unsigned long int num = 100;
double *linspaced;
