The batch managing processes run on psanasvc01 and are controlled by supervisord running under user psdatmgr. They seem to be using /usr/bin/supervisord, but I had trouble running that version (crashed) so I have run it out of the psana conda release.
The processes can be controlled (start/stop) using supervisorctl. The "-i" flag requests an interactive session:
supervisorctl -c /reg/g/psdm/psdatmgr/bin/supervisord_psanasvc01.conf -i
Useful commands are "avail", "stop <processname>", and "help".
