Jibing, The PINT_req_sched_post (and job_req_sched_post, called from the prelude state machine) don't have access to the hints structure. You would have to modify those calls to pass the hints to the request code. The hints sent from the client are available in the s_op->req->hints structure. One you have the hints in the request scheduling code, you can get at a particular hint value using the PINT_hint_get_value_by_type or PINT_hint_get_value_by_name calls. Both are declared/defined in src/common/misc/pint-hint.[h/c].
