I want to set up a Local Render Farm for an Animation. I got it to Work But my Slaves are taking forever to update the scene for each Frame (stuck for a long time atUpdating Lookup Tables and/or Updating Lights)
A standalone Render Takes about 2 minutes. The Scene loading time on the slave about 3 so it is slower at the Moment to Render in Farm.
Is there something i can do to solve this issue ?
Maybe manually copying the blend file.
Or is there an option to Render whole Frames as Slaves and not sharing each Frame ?
With best regard
Henrik

First of all thank you for your answer.
I found out that the CPU ist in 100% load for each Slave even though it was set to GPU only.
I found out that i had to Switch zu cuda manually on every Slave to Work with GPU.
This suprisingly fixed the Other issue too.
At the end i think it wasn't the sync time at all. IT seems that my slaves were so busy Rendering with CPU that they didn't send Feedback to the master. IT Tool a Long Time dir the spu because the tolle size was Set quite high for GPU Rendering.
Now it is working!
Each 6k frame Takes 2 Minutes Not 5. Thats a huge time saver!!
Hi Henrik :D I assume that what you are referring to is the 'sync' time, which includes things like copying data to the render kernel and building the BVH and so on?
This phase is dependent on;
1. the I/O speed of your storage for that node, since the file needs to be loaded into RAM before a render starts, this happens for each frame at the moment, a current limitation we're addressing in our new design.
2. the latency of your RAM and single core speed of your CPU, the 'sync' portion of the render creates a different representation of your scene for the render kernel, much of this is single core only and involves shuttling a lot of data between the CPU and RAM/VRAM, the more textures, particles, hair, mesh polys you have, the longer this takes.
So without knowing a bit about your hardware and the scene you are working with, its going to be difficult to recommend changes you could make :). Maybe you could reply with some information about your hardware and maybe a screenshot of what you have rendered?
