Setup guide

2 Troubleshoot the background processing network (page 126).
3 Review the Burn and Backburner logs from render nodes on the network.
1 Create a list of render nodes from which Burn and Backburner logs should be collected. On your
Creative Finishing workstation, log in to the account for your Autodesk application and open a
terminal. Run /usr/discreet/<product_home>/bin/GATHER_BURN_LOGS Run it with -h for usage.
This directory contains scripts and binary files for the application, including those used for
submitting jobs to the background processing network.
2 The script collects Burn and Backburner logs from each render node listed in the script and collates
these logs to a single text file. It uses the rsh protocol to access render nodes.
3 To avoid being prompted for login information while running this script, create a user account
on the workstation and populate the .rhosts file on each render node with the hostname of the
workstation followed by the username of this account. You can then use the -l option to run the
script as this user.
4 If these logs indicate that the problems may be due to background processing network components
such as Wire networking, then Test network components (page 130).
5 Assess compatibility between jobs and render nodes (page 131) if these logs indicate that the
problems may be due to memory issues on the render nodes, or if you suspect that the render
nodes do not meet the graphics card requirements for a certain job type.
4 If neither the logs nor the included scripts help you troubleshoot the problem with the background
processing network, contact Autodesk Media and Entertainment Customer Support.
Troubleshoot the background processing network
Problems with processing jobs may not be directly related to Burn but to background processing network.
Check connectivity
The following information and procedure applies to all components of a background processing network.
Burn works only when components on an Autodesk background processing network are communicating
with each other. For example, if Backburner Manager cannot contact the render nodes over the network,
jobs cannot be rendered remotely.
Use ping to test connectivity between components on the background processing network:
■ From the workstation, test connectivity between the Backburner Manager and each render node on the
network.
■ From the Backburner Manager workstation, test connectivity between the workstation and each render
node on the network.
■ From the render nodes on the network, test connectivity between the Backburner Manager and the
workstations that submit jobs to the background processing network.
Check network connectivity for jumbo frames
Jumbo frames increase the efficiency of a background processing network, but must be supported throughout
the network. Problems can be caused by jumbo frames being sent to a switch or network adapter that is
misconfigured or cannot handle these frames.
