Dears!

I've got issues with Network Rendering from 3ds Max - OCTANE 2.11.1a.

I've got 4x GTX 780 on first machina and 4xGTX 780 on second machine - both with active licenses.

When rendering using Network, everything seems to look OK - I've got 4/4 Network GPU info, etc, but when I look
on slave machine GPUs are alnost not used, and if - with very, very long idle pause.

I've got 1GB Network, and use of it is about max 5% - so I think it's not Network problem.

What can I do to take full profit form slave machine GPUs ?

Here is how it looks like on slave:

....Can anybody refer to my issue?

Thanks in advance.

gpus are paused to send data to the master machine
every summed pass causes an idle time.

I found the same issue and posted here http://render.otoy.com/forum/viewtopic.php?f=81&t=43037 with no reply from otoy

It seems to be a network bandwidth issue as when jumbo frames are used over the network the problem is reduced. 10gb network prices are not affordable by any means and therefore not a solution. Maybe a better solution will be for octane to send a lower amount of data in a more continuous way instead of doing it in bursts?

Is it a single frame rendering or you render an animation?

It's single frame.

6000pix wide.
Pathtracing Kernel.

Could you try 2.13?

Of course.

I'll test it and let you know.

OK, it's much better!

Here is how it looks now:
I'm wondering if I would connect two 1GB network connections it could help more...
On Network activity performance doesn't even exceeds 50% of bandwith...
