# Select Parent Job¶

As introduced in the header menu page, a completed "Parent" Job can be selected and added to a Job being designed from scratch. This new Job can in this way be based upon the Parent, and thus re-utilize its final results for further computation. These results are therefore "recycled", with the aim of optimizing the performance and computational time of the child Job.

In order to do so, the user should select the Select Parent option under the drop-down menu of the main header bar of Jobs Designer.

## "Select Job" Dialog¶

The "Select Job" dialog is now displayed with the following appearance, which is based on Jobs Explorer and thus supporting the corresponding filter/search functionality.

Criteria for Parent Job selection

Only Jobs that satisfy both of the following criteria are available for selection as "parents".

• The parent Job must be under either a "Finished" or "Terminated" status.
• The parent Job must have been executed on a cluster which is still available for use by the Account under consideration at the moment of the new Job creation.
