Sure. While I am finding time looking into this, could you talk a bit more about your application? The dynamic MPI processes is still a new territory despite its presence for many years. One of the reasons is due to lack of exposure for such applications.

Hi Hui,

That is exactly right, thanks so much for looking into it! Please let me know if you make any progress on this issue, as the application I am developing critically depends on MPI_Comm_spawn.

Best wishes,
