Load adjustments are used to increase the measured load after a job is dispatched. This mechanism prevents oversubscription of machines that is caused by the delay between job dispatching and the corresponding load impact. You can switch off load adjustments if you do not need them. Load adjustments impose on the scheduler some additional work in connection with sorting hosts and load thresholds verification.
To disable load adjustments, set job_load_adjustments to none and load_adjustment_decay_time to zero in the scheduler configuration. See Changing the Scheduler Configuration With QMON, and the sched_conf(5) man page.
