Hello, I'm very new using OpenMPI, so I was testing it and wrote this program:
//main.c
#include
#include
int main(int argc, char **argv)
{
int rank;
char hostname[256];
MPI_Init(&argc,&argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
gethostname(hostname,255);
printf("Hello world! I am process number: %d on host %s\n", rank,
hostname);
MPI_Finalize();
return 0;
}
and compiled using:
mpicc -o test main.c
but, when a run:
mpirun -np 4 test
it give me this error:
"mpirun noticed that the job aborted, but has no info as to the process
that caused that situation."
I'm using Ubuntu 14.04 and OpenMPI was installed from its repository.
Any suggestion.
