Sun N1 Grid Engine 6.1 Administration Guide

Sharing Override Tickets

The administrator assigns tickets to the different members of the override categories, that is, to individual users, projects, departments, or jobs. Consequently, the number of tickets that are assigned to a category member determines how many tickets are assigned to jobs under that category member. For example, the number of tickets that are assigned to user A determines how many tickets are assigned to all jobs of user A.


Note –

The number of tickets that are assigned to the job category does not determine how many tickets are assigned to jobs in that category.


Use the Share Override Tickets check box to set the share_override_tickets parameter of sched_conf(5). This parameter controls how job ticket values are derived from their category member ticket value. When you select the Share Override Tickets check box, the tickets of the category members are distributed evenly among the jobs under this member. If you clear the Share Override Tickets check box, each job inherits the ticket amount defined for its category member. In other words, the category member tickets are replicated for all jobs underneath.

Select the Share Override Tickets check box to control the total ticket amount distributed by the override policy. With this setting, ticket amounts that are assigned to a job can become negligibly small if many jobs are under one category member. For example, ticket amounts might diminish if many jobs belong to one member of the user category.

Clear the Share Override Tickets check box to control the importance of individual jobs relative to the ticket pools that are available for the other policies and override categories. With this setting, the number of jobs that are under a category member does not matter. The jobs always get the same number of tickets. However, the total number of override tickets in the system increases as the number of jobs with a right to receive override tickets increases. Other policies can lose importance in such cases.
