_SimpleCMD_QubeWorkerSelection

Example:

• A job submitted to /showB/lighting will run with its given priority in /showB/lighting cluster.

• If /showB/lighting is full, that job can run in /showB/FX, but at a lower priority.

• If both /showB/lighting and /showB/FX are full, the job can run in /showA/* at an even lower priority.

Host Order is a way of telling the job how to select/order workers

• • "+host.processors.avail" means prefer workers which have more slots available

  • "+host.memory.avail" means prefer workers which have more memory available

  • "+host.memory.total" means prefer workers which have more total memory

  • "+host.processor_speed" means prefer workers with higher cpu speeds

  • "+host.cpus" means prefer workers with higher total cpu slots

Requirements is a way to tell the workers that this job needs specific properties to be present in order to run. The drop-down menu allows a choice of OS:

• "winnt" will fill the field with "host.os=winnt" which means only run on Windows based workers

• "linux" will fill the field with "host.os=linux" which means only run on Linux based workers

• "osx" will fill the field with "host.os=osx" which means only run on OSX based workers

You can also add any other Worker properties via plain text. Some examples: 

• "host.processors.avail.=4" means only run this job on workers that have 4 or more slots available

• "host.processors.used=0" means only run this job on workers with 0 slots in use

• "host.memory.avail=400" means only run this job on workers that have 400 memory available

With integer values, you can use any numerical relationships, e.g. =, <, >, <=, >=. This won't work for string values or floating point values.

The 'Only 1 of a "kind" of job' checkbox will restrict a Worker to running only one instance with a matching "kind" field (see below). The prime example is After Effects, which will only allow a single instance of AE on a machine. Using this checkbox and the "Kind" field, you can restrict a Worker to only one running copy of After Effects, while still leaving the Worker's other slots available for other "kinds" of jobs.

Reservations is a way to tell the workers that this job will reserve the specific resources for this job.

Menu items:

• "host.processors" this will fill the field with "host.processors=X" which means reserve X slots on the worker while running this job

• "host.memory" this will fill the field with "host.memory=X" which means only reserve X memory on the worker while running this job

Other options:

• "host.license.nuke=1" when a Global Resources entry has been made you can reserve any arbitrary named item.

• See also Job Reservations

Restrictions is a way to tell the workers that this job can only run on specific clusters

Examples:

• submit a job that will run only in /farm:

  "qbsub -cluster /root -restriction /root"

   

• submit a job that will prefer to run in /farm/nuke, but could run in any host in /farm or in the first level below /farm

  "qbsub -cluster /root/a -restriction '/root or /root/*'"

  


• submit a job that will prefer to run in /farm/nuke/workstations, but could run in any host at any level at /farm or below

  "qbsub -cluster /root/a/workstations -restriction '/root or /root/+' hostname"
