Abstract

A method, system, and computer-readable storage device for selecting a platform configuration in light of a degraded makespan is described herein. A job profile of a prospective job, a normal makespan goal, and a degraded makespan goal may be obtained. The job profile may include a job trace summary. A simulation result of the prospective job may be generated based on a first simulation of the job trace summary on a platform configuration and a second simulation of the job trace summary on a degraded version of the platform configuration. The simulation result may include a predicted normal makespan and a predicated degraded makespan. The platform configuration may then be selected. In some cases the platform configuration may be selected via a purchasing option sent to a tenant.
