Job management device, cluster system, and computer-readable medium storing job management program

摘要

In a job management device: a request reception unit stores job-input information in a storage device on receipt of a job-execution request; and an execution instruction unit sends to one or more job-assigned calculation nodes a job-execution instruction together with execution-resource information, and stores job-assignment information in the storage device in association with a job identifier. When the contents of the job database are lost by a restart of the job management device, a reconstruction unit collects the job-input information and the job-assignment information from the storage device, collects the execution-resource information from the one or more job-assigned calculation nodes, and reconstructs the job information in the job database.
