    We have a big lab of 8 core machines. Many of our renders are not using the cores to their full capacity since there are some rendering features in Maya that aren’t multithreaded. Is there a way to tell Muster to treat an 8 core machine as two 4 core machines or even 4 two core machines? Also is there a way to have Muster run multiple batch render commands on one machine? That would solve the problem as well I think. Thank you.

    I have the same question that why Maya batch render can not use all of the cores.

    I’m relatively new to Muster (just been demoing it today), but I think this’ll solve your problem:

    Edit your config file for the render client, and, near the top, you should find, under [General]:

    instances = 1

    This defines how many slots are opened up when you start the client.

    Change this to 2 (or 4), and it’ll let 2 (or 4) things run on your machine at the same time.

    This won’t specifically limit the app to 4 or 2 cores per process, but it will allow more things on at the same time.

    If you modify that parameter just duplicate the number of instances and in the explorer yo can se the machines duplicated.

    I have the same problem. all the machines in our farm are rendering use only one core

    any ideas
    ???

    There is a way to control your core usage per machine via the management application. Right click select the machine you wish to change the cores on, go configure then click on the templates tab. From there select the render engine you are using, lets use mental ray as the example, there you will find a maximum threads setting, change from 1 – 4 threads or all. choosing 4 will allocate 4 core’s ect!

    hope this helps

    Exactly. But keep in mind this will work only with render engines that supports thread allocation. Otherwise , the only way is to spawn multiple instances. Processor affinity direct control is something we won’t support in the near future.

    How about enable multiple frame procession in AE? Which way has better performance, multiple instances in Muster or multiframe procession in AE?
    Further question, when enable multiple instances in Muster, how does it allocation processors and RAM?

    Multiple instances doubles (or 3x 4x..depending ont he number of instances) the RAM usage so you should play with it just if you’re sure your RAM is enough.

    Multiframe processing in Afx is enabled by the AFX preferences. You should log into AFX with the Muster user and store the preferences.
    The batch render will load them at the next invokation…
