GPU efficiency and

[protovu]

All drivers were updated with the recent Win10 upgrade. Had it done by an expert who built the system.

It is a client file, so I will try to make another failing file.

Hi protovu,

First of all, thanks so much for J.C's help! The suggestions are perfectly hitting home!

"Error binding socket......5131..." means port 5131 is being used by other applications at that time. Please ensure the port is available and do not run multiple OctaneServer programs at the same time. Besides, please make sure OctaneServer and the port are not blocked by the firewall.

About the GPU configuration and usage, as we don't have any additional settings about device configs on plugin side, running scene under Standalone might be the most useful way to locate issues. Thanks.
PS: I am not sure whether windows update can match the NV drivers perfectly. If it is possible, please fetch Nvidia drivers from the official website.

To use this version, you need a GPU of compute model 3.0 or higher. Support for Fermi GPUs (like GTX 4xx and 5xx) has been dropped. Also make sure you use a driver of version 387 or higher and if you are working on Mac OS that have a CUDA driver installed that supports at least CUDA 9.1.

Cheers,
DrawFun

HI Drawfun,

Ok, just updated from 417.35 to 417.71.

How can I determine what exactly is using the 5131 port?

Since I am able to start Blender and use the Preview for a while, does this mean that something else is starting on its own to access the port? If not, the Error message would come up immediately, correct?

You can check ports using system tools:

Hi Drawfun and JC,

So...I have a render going...(wait, actually it just crashed on frame 159), and simultaneously seeing the above image. Not sure exactly when the errors came up, as they usually appear behind the Blender App.
I notice them when minimizing the program or floating the cursor over the ORserver icon in my taskbar.

Am I supposed to see 2 instances of the OctaneServer in the listening ports?

You have to forgive me, but this is all Greek to me.

I have added an image corresponding to the restarted render...more port info. Render seems to be going ok now.

thank you for your help,
Rick

I have noticed that some times OctaneServer will not quit and I have to kill it manually. Doesn't happen often, but you can get these kinds of errors when it happens. It might be something different too as I'm on Linux, so YMMV.

[protovu]

Interesting..

Just to be certain order of things...., the drill to use Blender Octane is still:
turn on O-server,
then launch O-Blender.
yes?

Not necessary with my Carrara plugin. Both launch with Carrara.

[J.C]

There should be only one instance of the OctaneServer running on your system. Is it starting when you boot up your system?

When you run Blender-Octane the order is arbitrary. You can run Blender or Server first. Just double check if another server instance is not running.

[protovu]

With a single instance of the OctaneRender Server running, I definitely have the Octane Server on Listening ports 1024, 1025, 1026, 5130, 5131.

Something to do with dual CPUs and 4 cards?

[J.C]

On my system Octane Server has also several ports opened:
proto: tcp4 addr.port: *.5130
proto: tcp4 addr.port: *.5131
proto: tcp4 addr.port: *.1026
proto: tcp4 addr.port: *.1025
proto: tcp4 addr.port: *.1024
