supervisor_default_user_subjob_limit = limit
Limit specifies the default subjob limit, the maximum number of subjobs that any user may run simultaneously, across all process groups (pgrp). A value of -1 means "no limit". This may be reduced further by the pgrp subjob limit (see supervisor_default_pgrp_subjob_limit). For example, the user limit may be 200 subjobs, while the process group limit may be 50. So a given user could have a maximum of 200 subjobs running, and no individual prgp could launch more than 50.
