I honestly don’t think anyone has been concerned about the speed of
MPI_Comm_spawn, and so there hasn’t been any effort made to optimize it

Hi,
performance of MPI_Comm_spawn in the v1.8/v1.10 series is known to be poor,
especially compared to v1.6
generally speaking, I cannot recommend v1.6 since it is no more maintained.
that being said, if performance is critical, you might want to give it a
try.
I did not run any performance meas
Hi all,
I am trying to evaluate the time taken for MPI_Comm_spawn operation in the
latest version of OpenMPI. Here a parent communicator (all processes, not
just the root) spawns one new child process (separate executable). The
code I¹m executing is
main(){
{
Š..
// MPI initialization
Š..
start1
