Abstract
A method and a system for port access management at a distributed job manager, encompassing: initializing a port access process for each of one or more ports on a processing device; determining first whether a job is assigned to an active slot identified by an active_slot_id on the processing device, and when the determining is positive: determining second whether the job has been serviced by a port identified by the active_slot_id; and when either the first determining is negative or the second determining is positive then: retesting the first and second determining; else: determining whether the job requires an access to the port identified by the active_slot_id; and when the determining is positive: fetching the port's configuration words; processing the fetched port's configuration words; marking the job as serviced by the port upon conclusion or the processing of the fetched port's configuration words; and recalculating the value of the active_slot_id.
