While setting up the hardware setting of a job, you will see priority options under the Price column. You will have either On Demand, On Demand Pro, or both options depending on the hardware availability. An example is shown below:
When to Use On Demand Mode
Selecting the On Demand mode will submit your job into the run queue, but it may experience a moderate delay before the run is started. Moreover, once the job begins to run, depending on resource demands, the job maybe be automatically stopped and restarted. Therefore, the On Demand option is not generally recommended for jobs with long run times or subject to upcoming deadlines.
However, the benefit to running the On Demand setting is a reduced price point as compared to the On Demand Pro mode.
Note that there is currently a limit on the number of On Demand cores and walltime you can set on a single job. More information here
Please refer to Rescale Job Service Level Agreement (SLA) here
Meaning of the On Demand Settings
If you do decide to use On Demand mode, when there is a green “i” symbol, this indicates that On-Demand for this core-type is still in beta, the job may be terminated by the provider and it may not be automatically restarted.
When this symbol is yellow, it indicates that On-demand for this core-type is still in beta, the job may be terminated by the provider and it may not be automatically restarted.
