    Jobs can be submitted from WranglerView using the items under the Submit menu. Selecting one will launch a modal submission dialog with the standard framework and job-specific parameters. Specify the fields and then press the "Submit" button to submit the job to the Qube! Supervisor.

    Submissions for specific applications, such as Maya and Nuke, are explained in detail in their own section. Please refer to that documentation for submissions to individual applications. This page documents the complete set of parameters; specific submission targets do not use all the parameters defined here.


    There is a common set of buttons located at the bottom of the Submission Dialog.

    • Set Defaults: Store as defaults in the User Preferences for that Jobtype, the values listed in the current submission dialog. The interface will use those values the next time the dialog is opened. This allows you to specify common fields like Priority or Executable that should always be the same value.
    • Clear Defaults: Remove any stored defaults for that Jobtype submission dialog
    • Expert Mode: Toggle button to display or hide export and non-default values from the submission dialog to reduce clutter when there are a lot of parameters. The current state of this toggle is stored in the Preferences Dialog.
    • Save [Disk Icon]: Store the current properties of the job from the dialog as a file (by default an XML file). This can be used to submit through the WranglerView at a later time with "Submit->File…" or from the command line with the qbsub command, or via the API.
    • Cancel: Cancel the job submission and close the dialog.
    • Submit: Submit the job with the specified parameters to the Qube! Supervisor.

    Basic Parameters

    Basic Parameters for all Jobs:

    • Name: name used for the job, usually artist specified.
    • Priority: priority of the job. A number between 1 and 9999. Lower numbers mean higher priority.
    • CPUs: The number of processes (or subjobs/instances) to run the job with at the same time. When rendering, this equates to the number of frames being rendered at the same time.

    Render Thread and Job Reservation Controls

    This section is located near the top of the submission UI, and is collapsed when 'Expert Mode' is not selected.  For applications that do not support setting the number of threads, this section is not visible at all.

    Enabling 'Expert Mode' at the bottom of the UI will open this field up


    Use Slots=Threads only on farms where the workers are configured to have as many slots as they have cores; they will show 0/8 or 0/16 in the Slots when they're empty, where the 0/N number is the number of free slots. This is the default configuration in Qube!

    The other common configuration is all the worker set to only ever accept 1 job, where they show 0/1 in the Slots column in the UI. Do not use Slots=Threads in this configuration, since none of your workers will have enough free slots to accept the job.

    Thread Control Behavior:

    Checking Use All Cores for applications or renderers that support auto-detection of the number of cores installed on a worker host will set the renderer's appropriate control to enable this feature. In the case of a Maya job, it sets renderThreads=0; for the Mentalray renderer, it sets autoRenderThreads=True.  It will try to "do the right thing" for each application where this control is visible.

    Checking Render on all cores will also sets the job's reservation string to reserve all cores: you will set a "+" at the end of the host.processors=N+ . This means "only start on a worker with N free slots, but reserve them all, so that no other jobs will start on this worker while I'm running on it".  The Min Free Slots value will affect the value of N, so setting it to 4 will say "start only on a worker with 4 free slots".

    Render on all cores also disables the bottom-half of this section, Specific Thread Count and Slots=Threads, whose behavior is explained below.

    Setting Specific Thread Count, on the other hand, does not necessarily reserve all the cores on the worker, it only sets the renderer's particular number of threads control, in Maya's case it's Render Threads:

    But you will notice that the job's reservations have not changed, and is probably still at the default value of host.processors=1.  This is to support workers which are configured for fewer slots than they have cores.

    The Slots=Threads control will link the job reservations to the thread count, so a 4-threaded job will reserve 4 worker slots.  It also disables the Render on all cores and Min Free Slots controls.

    As you change the Specific Thread Count control the reservations value will automatically update.

    Parameters for Cmdline Jobs:

    • Command: The command to run on the Worker. Paths and syntax should be what the Worker's OS expects, not the submitting machine.
    • Shell (Linux/OS X): Specify the shell to use when executing the command line on the Worker. Only visible in Expert Mode.

    Parameters for Cmdrange Jobs:

    • Command: Same as the Cmdline Job, though it will substitute the following strings based on the frame being executed for the given task.
      • QB_FRAME_END
    • Range: The frame range to execute.
    • Execution
      • Individual Frames
      • Chunks with n Frames
      • Split into n Partitions
    • Ordering: Specify whether tasks should be executed in ascending, descending, or binary sort (first, last, middle, split the middle values, …) order.

    Common Parameters for SimpleCmd Jobs:

    • All the fields for either Cmdline or Cmdrange jobs (see above), plus
    • Cmd Template: String used to construct the command line along with the rest of the job parameters. Python string representations are used, e.g. %(val)s to represent the string value from "val". If listed, %(argv)s places all optional arguments at that location instead of at the end. This constructs a command line that is then used by the Cmdline or Cmdrange jobtypes on the Workers. See above for the string replace values for CmdRange.
    • Executable – path to the renderer or executable to run. Unless it is in the path on the Worker's environment, this needs to be set to an absolute path (to where the executable is located on the Worker)

    Detailed Parameters

    Qube Worker Selection

     Click here for details...


    Explicit list of Worker hostnames that will be allowed to run the job (comma-separated).


    Explicit list of Worker groups that will be allowed to run the job (comma-separated). Groups identify machines through some attribute they have, eg, a GPU, an amount of memory, a license to run a particular application, etc. Jobs cannot migrate from one group to another. See worker_groups.

    Omit Hosts

    Explicit list of Worker hostnames that are not allowed run the job (comma-separated).

    Omit Groups

    Explicit list of Worker groups that are not allowed to run the job (comma-separated).

    Priority Cluster

    Clusters are non-overlapping sets of machines. Your job will run at the given priority in the given cluster. If that cluster is full, the job can run in a different cluster, but at lower priority. Clustering


    • 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

    Order to select Workers for running the job (comma-separated) [+ means ascending, - means descending].

    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

      • "" 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



    Worker properties needed to be met for job to run on that Worker (comma-separated, expression-based). Click 'Browse' to choose from a list of Host Order Options.

    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. Multiple requirements can also be combined with AND and OR (the symbols && and || will also work).

    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.



    Worker resources to reserve when running job (comma-separated, expression-based).  

    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. New in 6.6: Once you create a global resource, it will show up in this menu (eg global.vray above).

    • See also Job Reservations



    Restrict job to run only on specified clusters ("||"-separated) [+ means all below, * means at that level]. Click 'Browse' to choose from a list of Restrictions Options.

    Restrictions is a way to tell the workers that this job can only run on specific clusters. You can choose more than one cluster in the list.


    • Choosing /showA would restrict the job to machines that are only in the /showA cluster, and no other cluster, not even those below /showA.

    • Choosing /showA/* would restrict the job to the cluster(s) below /showA, but not including /showA

    • Choosing /showA/+ would restrict the job to /showA and all the clusters below it.

    List of submission flag strings (comma separated). Click 'Browse' to choose required job flags.


    See this page for a full explanation of flag meanings



    Wait for specified jobs to complete before starting this job (comma-separated). Click 'Add' to create dependent jobs.

    You can link jobs to each other in several ways:

    • "complete" means only start this job after designated job completes
    • "failed" means only start this job if the designated job fails
    • "killed" means only start this job if the designated job has been killed
    • "done" means start this job if the designated job is killed/failed/complete

    The second menu chooses between "job" (the entire set of frames) and "work" (typically a frame). So to link frame 1 of one job to frame 1 of a second, job, you would choose "work" in this menu. If you want to wait for all the frames of one job to complete before starting a second, then choose "job". The other option, "subjob", refers to the instance of a job. This is much less common, but means that, for example, the instance of Maya that was running frames has completed.

    For a complete description on how to define complex dependencies between jobs or frames, please refer to the Callbacks section of the Developers Guide.

    Email (job complete)

    Send email on job completion (success or failure). Sends mail to the designated user.

    Email (failed frames)

    Sends mail to the designated user if frames fail.


    Set initial state of job to "blocked".


    Redirect and consolidate the job stderr stream to the stdout stream. Enable this if you would like to combine your logs into one stream.

    Job Label

    Optional label to identify the job. Must be unique within a Job Process Group. This is most useful for submitting sets of dependent jobs, where you don't know in advance the job IDs to depend on, but you do know the labels. 

    Job Kind

    Arbitrary typing information that can be used to identify the job. It is commonly used to make sure only one of this "kind" of job runs on a worker at the same time by setting the job's requirements to include "not (job.kind in host.duty.kind)". See How to restrict a host to only one instance of a given kind of job, but still allow other jobs

    Process Group

    Job Process Group for logically organizing dependent jobs. Defaults to the jobid. Combination of "label" and "Process Group" must be unique for a job. See Process group labels

    Retry Frame/Instance

    Number of times to retry a failed frame/job instance. The default value of -1 means don't retry.

    Retry Work Delay

    Number of seconds between retries.

    Subjob Timeout

    Kill the subjob process if running for the specified time (in seconds).  Value of -1 means disabled. Use this if the acceptable instance/subjob spawn time is known.

    Frame Timeout

    Kill the agenda/frame if running for the specified time (in seconds).  Value of -1 means disabled. Use this if you know how long frames should take, so that you can automatically kill those running long.

    Qube Job Environment

     Click here for details...


    Current Working Directory to use when running the job.

    Environment Variables

    Environment variables override when running a job. You can specify key/value pairs of environment variables

    This is useful when you might need different settings for your render applications based on different departments or projects.

    Impersonate User

    You can specify which user you would like to submit the job as. The default is the current user. The format is simply <username>. This is useful for troubleshooting a job that may fail if sent from a specific user.

    Setting "josh" would attempt to submit the job as the user "josh" regardless of your current user ID.

    Note: In order to do this, the submitting user must have "impersonate user" permissions.

    Qube Output Parsing and Validation
    • Min File Size
      Used to test the created output file to ensure that it is at least the minimum size specified. Put in the minimum size for output files, in bytes. A zero (0) disables the test.

    • regex_highlights
      Used to add highlights into logs. Enter a regular expression that, if matched, will be highlighted in the information messages from stdout/stderr.

    • regex_errors
      Used to catch errors that show up in stdout/stderr. For example, if you list "error: 2145" here and this string is present in the logs, the job will be marked as failed. This field comes pre-populated with expressions based on the application you are submitting from. You can add more to the list, one entry per line.

    • regex_outputPaths
      Regular expression for identifying outputPaths of images from stdout/stder.  This is useful for returning information to the Qube GUI so that the "Browse Ouput" right-mouse menu works.

    • regex_progress
      Regular expression for identifying in-frame/chunk progress from stdout/stderr. Used to identify strings for relaying the progress of frames.

    • regex_maxlines
      Maximum number of lines to store for regex matched patterns for stdout/stderr. Used to truncate the size of log files.

    Qube Actions
