without calling Finalize, they all need
to do so else you will hang in Finalize. The problem is that Finalize invokes a
barrier, and some of the procs aren't there any more to participate.

Hi Ralph,
Thanks for your response.
I see your point, I try to change the algorithm but some processes finish while
the others are still calling MPI functions. I can't avoid this behaviour.
The ideal behavior is the processes go to sleep (or don't use the 100% of load)
when the MPI_Finalize is
Hi all,
I have a performance problem with the next code.
int main( int argc, char *argv[] )
{
MPI_Init(&argc, &argv);
int myid;
MPI_Comm_rank(MPI_COMM_WORLD, &myid);
//Imagine some important job here, but P0 ends first.
if (myid != 0)

Hi,
I am running the NAS parallel benchmarks and I have a performance problem
depending on the hostfile configuration. I use Open MPI version 1.7.2.
I run the FT benchmark in 16 processes, but I want to overload each core
with 4 processes (yes, I want to do it), so I execute:
time mpirun --hostfi
