Squidnet - Monitoring Jobs

Once a job has been submitted to the render farm, the squidnet master node finds available nodes to work on the jobs slices. Lots of things can go wrong with these jobs. Squidnet will try several times when errors do occur but after a certain number of failures it assumes something is wrong with the job or stations and will stop the job. Sometimes you can fix it and requeue the job but many times you have to create a new job with the changes needed.

Lets see what squidnet is working on and see how our example project is doing.

  1. Start the Squidnet.UI program
  2. Select Job Queue from the Tools menu to see whats in the queue and what is being worked on.
  3. In the queue you can see what jobs are waiting for work and which are currently being processed. Jobs with too many failures will appear red.squid-jobqueue.jpeg
  4. I see my job is currently processing without any errors. Double click on the job to see the individual slices. I can see my job is being processed on several machines. I am doing 5 frames per slice and it takes about 15 minutes to complete a slice. Pushing that out to a room full of computers will get it done pretty quick. When the slices are completed the output folder will have those images in it. Items labeled Queued are awaiting an open station. Anything with error means something went wrong. That slice will be retried a few times on a different station. Once five errors have occurred the job will stop processing.squid-slicelist.jpeg
  5. If you select a slice and right mouse click you can view the Application Log to see the text results from the command. Do this on Error slices to see what caused the error. This sample is from a successful slice so no errors here.squid-applog.jpeg
  6. If you see error message about missing texture files, you may need to repackage the scene and update the texture paths.

Once the job is complete you should see the image files all show up in the output. Now the last step is to turn it into a movie file.
