Jobs Reserving Resources
All resources must be reserved by job processes by setting the "reservations" field at job submission. For example, setting the reservations field to global.shake=1 will have the job reserve 1 of the global.shake resources for each job process. By default…Priority
The priority algorithm is a numeric priority queue. Normally, the priorities are established such that lower values are considered to have higher priority. For example, a job with priority 1 will have a higher priority than a job with priority 10. The def…Global Resources
Global resources are defined in the Supervisor using the qb.conf file. The configuration parameter is called supervisor_global_resources This subject is covered in depth in the section System-Wide Resource Tracking The following specifies the configuratio…Clustering
A diagram showing how the same 4 jobs have their priority sorted differently depending on which cluster the job and worker are each in. Workers in the / cluster (also known as the 'root') Jobs are sorted by priority then by job id (first come, first serve…Validating the qbwrk.conf
After the qbwrk.conf file is edited, you should check the file for validity. This can also be used to verify macros and inheritance templates. As Administrator (or sudo), run the qbconfigfile command on the qbwrk.conf file. Depending on your OS, that will…Scoped Resources
Scoped resources are similar to global resources in that they govern a resource available to the entire system. However, they may also be restricted on a per-host basis as well. For example, a site may have a certain number of software licenses, and be re…License Resources
License resources work exactly like global resources with the added advantage that they can be dynamically updated in the Supervisor by an external application. Normally, as jobs are dispatched and executed, the Supervisor continually updates the global r…Per-User and Per-Pgrp Instance Limits
Qube! has the notion of per-user and per-pgrp instance limits. The administrator may set these limits to pose a restriction on the number of job instances that each user or pgrp may run on the farm at once. In addition to setting up global default value…Client Configuration
A client is something (often a machine) that is going to submit jobs, but not run them. Compared to the Worker, client configuration is a very simple process - the only thing that requires configuration is the name of the Supervisor. The Supervisor settin…Per-Host Global Resources
Per-host global resources are very similar to the original global resources, but differ in that they track resources that are consumed on a per-host basis, not per-instance. For example, they may be used to track application licenses where a single licens…
