By default Qube! chooses any host (Worker) in the list of hosts which qualify. If given a choice, a job is allowed to prefer a particular host based upon its attributes. This is established using the Qube! resources and priorities defined earlier in the Requirements section of this document.

- host.memory
- host.processor_speed
Syntax
[+|-]host.property
[+|-]host.resource.[total|used|avail]
The + or - in the expression is used to determine if the job would prefer the largest or smallest value possible. If neither is used, + is assumed.

Notes
Note that the The system will use the hostorder specification only when initially choosing the most preferable Worker for the job itself. Once it has chosen a host, it will try to fill it up with instances from the job until the host is full. In other words, the system will not attempt to apply the hostorder to select a host for each individual instance.
