    I have 100 licenses. but only 10 nodes work - Host 192.168.10.187:20207 added to wai

    Hi all,
    I've installed VRay Standalone on a cluster based on Ubuntu.
    I've bought "10 VRay Standalone Pack" licenses, so I have 10x10 licenses for DR.

    How does my system work?

    In a loop I run a script which renders frame by frame in following steps:
    1. Take 10 nodes for rendering the current frame.
    2. The 1st one is master, other 9 are slaves.
    3. Run on each slave vray -server.
    4. Run vray -distributed=1 (with other params) on master node.
    5. Rendering image on 10 hosts.
    6. After all work killall -9 vray on each slave.

    What is happen when I start rendering 6 frames?

    ad. 1. Script reserves 60 nodes (6x10) for my jobs.
    ad. 3. Script runs 54 vray -server which take 54 licences from my licensing server (I can see IPs of current nodes).
    ad. 4. Script runs 6 vray in master mode which take 6 licences.

    ad. 5. Here I have a problem.
    The first job has in its log:

    [2013/Feb/7|15:17:18] ========================
    [2013/Feb/7|15:17:18] Starting frame 0.



    And when I reserve only 5 nodes per job (one frame), I'll get:

    1st frame: Using 4 hosts for distributed rendering.
    2nd frame: Using 4 hosts for distributed rendering.
    3rd frame: Using 2 hosts for distributed rendering.
    4th and others: Using 0 hosts for distributed rendering.

    In licensing server I can see 40 nodes.


    Could somebody explain what I'm doing or maybe I don't understand how license server works. I'll be much grateful.


    PS. I've been thinking...

    I've got license server on one host (for instance 10.0.0.1).
    The nodes of the cluster are in a private network (192.168.10.255) and the cluster has one public IP (for instance 10.10.10.2).
    On the list of my license server there are:
    Sessions list for VRay Standalone/Adv 2.0 GUI RENDER DR Last access
    192.168.10.217 0 0 0 1
    192.168.10.153 0 0 0 18
    192.168.10.128 0 0 0 18
    192.168.10.216 0 0 0 1
    etc.

    Is it possible the license server sees all these master nodes (which run vray -distributed=1) as one machine with the external IP 10.10.10.2 and thus only 10 licences work in DR in the same time?
    Notice the other master nodes render frames as well, but without slaves.

    PS2. One (maybe) important thing more. The all nodes have shared home directory, where VRay is installed. The nodes see home folder as their own and they simply run it. To clarify. Let's say I have 200 nodes. I had to install VRay only once, but it could be run 200 times.

    Are you sure all the slaves are correctly configured to see the license server?

      Hi Vlado and thank you for your time.
      I can ping my license server from the nodes.
      When I start vray (master or slave) the nodes connect to license server and receive one of them.
      However, I noticed one thing yesterday.

      On the top of the license server's site I tables with info about my licenses. Here are they:
      ----------------------------------------------------------------------
      V-RayStd/Adv (1.0/2.0) Total Engaged Free
      Render licenses 10 / 10 0 / 0 10 / 10
      Interface licenses 10 / 10 0 / 0 10 / 10
      DR licenses 10 / 10 0 / 0 10 / 10
      ----------------------------------------------------------------------
      VRay Standalone/Adv 1.0 licenses list GUI RENDER DR Expires
      Dongle SN: XXXXXXXXX 10 10 10 Never
      ----------------------------------------------------------------------
      VRay Standalone/Adv 2.0 licenses list GUI RENDER DR Expires
      Dongle SN: XXXXXXXXX 10 10 10 Never
      ----------------------------------------------------------------------

      When I was buying the licenses (I didn't know VRay) I was informed that 1 license for VRay Standalone allows distributed rendering on 10 nodes. Is it right?

      If not, I have a serious problem.
      If so, I may do something wrong or I need to call sellers and explain it.

        I see. You get 10 DR licenses each time you buy a full license of V-Ray for 3ds Max or Maya (essentially, you get 10 standalone licenses bundled). However one standalone license is just one standalone license for rendering or DR (no extra DR nodes included).

        If there is any misunderstanding and this is not what you expected, we will of course refund your money back. At this point, it might be better to send an email to support@chaosgroup.com to clear things up.
