A neural processing device and a method for job scheduling are provided. The neural processing device configured to receive, by an address space ID (ASID) manager, first and second requests from at least one context, respectively, and determine whether ASIDs are allocated, store jobs of contexts to which the ASIDs have not been allocated from the ASID manager in entities, schedule, by a job scheduler, an execution order of the jobs stored in the entities and cause the ASID manager to allocate the ASIDs to the contexts to which the ASIDs have not been allocated among the at least one context, and sequentially receive, by a command queue, jobs of contexts to which the ASIDs have been allocated, store the jobs as standby jobs, and sequentially execute the standby jobs.
