1. A computer system for managing a flow of batch jobs, comprising:

  • a memory comprising a plurality of jobs within a batch queue grouped together into one or more services that each comprises a job and a predecessor job, wherein a time difference comprises the difference between a scheduled start time of the job and an estimated end time of the predecessor job, wherein jobs with a preceding time gap comprise jobs immediately preceded only by non-zero time differences, and wherein the job start depends upon the predecessor job completion; and

    a processing unit, coupled to the memory, that identifies those jobs of the plurality of jobs preceded by a time gap, selects a service of the one or more services, and traverses in reverse chronological order a critical path of dependent jobs within the selected service until a latest job with a preceding time gap is identified or until at least those jobs along the critical path preceded by another job are traversed.
