You could: 1)Write your own load sensor that reflects your notion of which node is more preferable then use that for the load_formula. 2)Change the queue_sort_method to seqno and give the queues on hostA a lower sequence number. You could add a np_load_avg based load_threshold that will stop jobs being assigned to a host if it is overloaded.
