Alfred can send jobs to remote hosts arond the local area network and utilize their CPUs to render images. But how to?

First, Alfred needs to know where to find the remote hosts. You need to edit hosts file, which is located in C:\windows\system32\drivers\etc. Open hosts in editor, default one should be:

127.0.0.1       localhost

add more lines:

192.168.0.202 renderserver02
192.168.0.204 renderserver04

IP address followed by server name.

Open Alfred->Scheduling->Master Schedule... There will be 2 fields, newly added hosts will be listed in the right field. Include them into the left field. Set proper number of Slots (CPUs). Save schedule.

Open Alfred->Scheduling->Huntgroup, select those hosts and click New Jobs. They will be used when any new jobs are submitted.

On all remote hosts, start alfserver.exe in the bin folder of RMANTREE, renderman installation path. Alfserver.exe listens to and receives jobs from Alfred on your local host and starts prman.exe on its host to render the job. Keep it running.

Finally, on your local host, before launching a render in Maya, set RenderMan Controls->Spool->Job Setup, choose netrender as renderer.

Done! You can render with remote CPUs.
