2 User Interface


SquidNet Render Manager - Main GUI

The figure above shows a sample screen of SquidNet’s main user interface. The GUI application uses a multiple document interface (MDI) format in which multiple window “views” reside under a single parent window. This MDI format allows for the creation of custom window layouts by arranging the views in any order.

The main GUI is composed of the following sections:

  • 1. Main Menu: Selectable menu items (Project, View, Network, Tools, Admin, Window, Help).
  • 2. Main Toolbar: Quick access buttons for commonly used views.
  • 3. Status Bar: Overall summary of render farm status (Queued jobs, nodes online, uptime, etc…)
  • 4. View Windows: Selectable windows placed anywhere within the appplication background screen.

The figure above also represents a typical layout of render farm views:

  • Project Folder View: List of project job profiles (Project->Project Manager).
  • Job Queue View: Shows queued jobs (Tools->Job Queue).
  • Image Preview View: Shows output folder contents by clicking on queued job (Tools->Image Preview).
  • Render Farm CPU Nodes View: Lists all render farm nodes and their status’ (Network->Render Farm).
  • Render Farm Work Queue View: Lists active render nodes and the jobs they’re working on (Network->Network Work Queue).

To start the SquidNet user interface:

Windows: Look for “SquidNet User Interface” in main start menu or look for the SquidNet icon on your desktop. Installed under “C:Program Files (x86)SquidNetSoftwareSquidNetsquidnet-ui.exe”

Mac OS: Open /Applications/SquidNetSoftware/SquidNet/squidnet-ui.app/Contents/MacOs/squidnet-ui

Linux: Open /opt/squidnet/squidnet-ui.sh


To create and load/save custom view layouts, use the Custom Layouts Manager (Window->Customer View Layouts)

2.1 Project Menu

2.1.1 Project Manager


Project Manager

For local jobs, SquidNet stores all job profiles inside of project folders. Open the project folder (Project->Project Manager …) to create or select specific project folders. Project folders and their content is stored in the SquidNet configuration folder.


Project Folder

Project folders contain all your job profiles. When a new job is submitted to the farm, you’ll be asked if you’d like to save it to the local project folder. Saving of job profiles is recommended if you’d like to reopen a previously submitted job, adjust a few rendering parameters then resubmit.

Project folder options are as follows:

  • Project: Select a new project folder.
  • New Job: Create a new job.
  • Submit: Submit selected job profiles then submit to the farm.
  • Refresh: Refresh job profile list.
  • Template: Only list specific applicaton types within the folder.
  • Filter: Filter job profiles by text.

2.1.2 Job Profile


Job submission from template form.

Creating a new or opening an existing job profile in the Project folder window opens up an application template. The template contains all the rendering parameters for a specific job type.

Job template field descriptions:

  1. Template: The type of application that will process this request:
  2. Project folder: The project that this job will belong to.
  3. Scene/shot name: Name of the shot that this scene belongs to. By default, all scenes belong to the “Default” shot. Use the “+” or “-“ buttons to the right of the shot name to add or remove shot names to/from the list.
  4. Auto-generate job id: Press repeatedly to regenerate new job id.
  5. Use scene name: Extract the scene name and use that name as the job id,
  6. Job id: Identifier used to track job on the farm.

  8. Max Slices: The maximum number of active job slices. Defaults to distribute as many slices as possible.
  9. Use all cores: If checked, use all available cores for each job slice.
  10. Slice Timeout (multiplier): Automatically requeue any job slice that exceeds the average processing time of the other slices within the same job.
  11. Start Suspended: Initially queue job into a suspended state.
  12. Slice Timeout (mins): Automatically requeue any job slice that exceeds a specific rendering time (in minutes).
  13. Randomize job slices: Randomly process job slices (as apposed to processing sequentially (default)).
  14. Slice fails before stop: Set the maximum number of allowed per-job slice errors before job processing is halted.
  15. Skip frame: Don’t process frames that already exist in output folder.
  16. Check output content: Verify that output folder contains rendered content. If not, error out job.
  17. Create output folder: If not present, create output folder directory.
  18. Frame Check: Automatically requeue missing or corrupted output frames.
  19. Estimate Completion Time: Just render a single frame to determine total job completion time.
  20. Priority: 25 different processing priorities (0-24). “0” being the highest priority and 24 being the lowest.
  1. Render Pools: Assign render pool(s) to this job.
  2. Include/Exclude: Assign jobs to ONLY render on specific nodes or to NOT render on specific nodes.
  3. Tile Rendering: Tile render settings.
  4. Advanced: Advanced job settings.
  5. On Job Completion:: Dispostion options when job completes.
  6. Submit: Submit job to farm.
  7. Apply: Submit job to farm but leave submission window open so that adjustments can be made to rendering parameters.
  8. Save: Save job profile and close submission window.
  9. Cancel: Undo all changes and close submission window.
