Chapter 2 Preparing a Network for Distributed Processing 29
Additional Steps For Part-Time Distributed Processing
With Shake
The following additional steps may be necessary for Shake users who cannot
consolidate all of the necessary source files (Shake scripts, media files, etc.) on
a single cluster storage volume.
Step 1: Turn off the UNC (Universal Naming Convention) setting for Shake
To make sharing and volume mounting work smoothly in this setup, you need to
turn off the Shake UNC setting on each computer. The UNC setting uses the entire
file pathname, with the network address, in a convention that starts with
//ComputerName/DriveName/path. You don’t want Shake to use this filenaming
convention because it conflicts with the file sharing and volume mounting used in
this setup.
Note: All the media volumes created in Step 2 of “Configuring Access for Part-Time
Distributed Processing,” above, should have the same name.
The Shake startup .h file
In the three steps below, you make this change in a Shake startup .h file. As described
in the Shake documentation, the startup .h files, located in the startup directory, are
used to customize Shake settings (similar to setting preferences).
To turn off the UNC setting, do the following on each of the computers:
1 Log in as the user who will use Shake on the computer.
2 Double-click the Terminal icon in /Applications/Utilities to open a Terminal window.
3 Enter these two command lines in the Terminal window, pressing Return after each
command line:
mkdir -p ~/nreal/include/startup/
echo 'script.uncFileNames = 0;' > ~/nreal/include/startup/UNC_off.h
Step 2: Turn Personal File Sharing on
On each computer, open System Preferences, click Sharing, and turn on Personal File
Sharing. This allows the computers to share the media volumes.
Step 3: Mount all the media storage volumes
On each computer, log in as the administrator. (The first user account you create when
you set up Mac OS X is an administrator account.) Then, on each computer in the
group, use the Connect to Server command in the Finder’s Go menu to mount each
media volume.
