A computer system and a parallel execution control method thereof. A job execution managing module includes a job control statement interpreting module for deciding by interpretation of job control statements whether jobs registered by a job registration processing module are capable of undergoing parallel execution. For the jobs susceptible to the parallel execution, the job execution managing module commands reregistration of such job to the job registration processing module. The job control statement interpreting module further decides by interpreting the control statement whether execution of individual job steps of registered jobs are to be skipped or not. The job step decided to be skipped is inhibited from execution by a step execution control module. Time taken for execution of jobs and job steps can be shortened.
