PRRTE should work on Summit. I've not tried in a long time though. You will need to request an allocation without JSM (since you won't be using it). Something like "bsub -jsm n" should work. Then you will need to launch PRRTE using the hostlist information from LSF/CSM via ssh.
If you are hitting a snag with the software ecosystem on Summit that you need help with just let me know offlist and we can try to sort it out.
