It’s possible but not prioritized. Could you open an issue on github? When we have enough users requesting the feature (or when we have persistent user requesting it), the priority may be escalated. 😊 Meanwhile, could you describe the scenario that you have to use singleton init (vs. `mpirun -n 1 prog …`)?

Subject: [mpich-discuss] Spawns without mpirun

Hi all!
I asked here some time ago about dynamically spawn processes  from a singleton but the answer was that unfortunately, there was a problem with that and just It was not possible. I wonder now if this functionality is available.
Best regards
