A mechanism is provided for estimating the amount of time needed to execute a job. The mechanism receives a request to execute a new job. The mechanism processes the request to determine the job profile signature for the new job, which is based on a set of job characteristics of the new job. The mechanism also selects a candidate machine from a plurality of machines in a computing grid which contains an available time slot, and determines a machine profile signature for the candidate machine based on a set of machine characteristics of the candidate machine. The mechanism accesses and obtains from a database execution estimation information based on actual execution information associated with previously executed jobs having identical job profile signatures as the new jobs and which have been executed on machines having identical machine profile signatures as the candidate machine. Based on this execution estimation information, the mechanism derives an estimate of the amount of time need to execute the new job. By estimating the execution time in this manner, the mechanism enhances scheduling efficiencies for jobs submitted to the computing grid.
