Hardware On Demand

Overview

While setting up the hardware setting for a job, several priority options may appear in the Price column: On Demand Priority and On Demand Economy, depending on what is configured for the selected coretype.

Price Options
Figure 1: Price options

On Demand Priority

The On Demand Priority option is a job service level for general use and high availability.
On Demand Priority allows you to run your jobs to completion without any interruption from the cloud service provider. Therefore, this hardware setting is most suitable for long-running or time-sensitive jobs.

On Demand Economy

The On Demand Economy option is a job service level at a reduced price point compared to the On Demand Priority option. Selecting this option submits your job to the run queue, but the job may experience a moderate delay before the run is started. 

Once the job begins to run, depending on resource demands, the hardware the job is running on may be reclaimed by the cloud service provider at any time, with or without warning. In general, Rescale will attempt to restart your job with a priority level you can work with us to configure. For example, you could choose to always restart on a non-preemptible instance or to attempt up to five restarts, with the last restart being On Demand Priority.

Therefore, the On Demand Economy option is not generally recommended for jobs with long run times or subject to upcoming deadlines.
