It's a possibility, pre-computation can be limited to one thread. But the OS doesn't limit a process, it's Debian and the priority of the processes are managed by "nice" command. I can easily freeze the system by running a loop a the highest process priority, and it's not the case with a Blender ren...

Thanks for the suggestion. I tried to increase tiles to 360 (60x60) and run with 4 threads but, against all expectations, this not decrease the render time (+300s...) and the processor is used only at ~7% (~15% of one core). If I increase threads to many more like 16, the render time decrease but al...

This processor is out less than one year and running on 64GB of ECC memory on SSD with RAID hard, the problem donesn't come from the hardware. And the simple proof is it can assign and work with more memory in less time (4 processes VS 4 threads). My 3 workers as you said have the same memory capabi...

I'm not sure to understand, the CPU is used entirely only if I run multiple render (so multiple process) and never when I use Blender to build the threads. I don't really know the problematics about shared memory between threads, but Blender should use all the cores and all the CPU, it's not normal ...

Linux ommand line render never uses all CPU threads

I'm running blender on Debian 6 64bit with CPU rendering on a Xeon E31220 cpu @3.1GHz (4 threads) and I render an animation of 128 frames to PNG files with 14 tiles (4*4). Command line is like : blender -b model.blend -o '//###.png" -F PNG -s 0 -e 127 -noaudio --render-anim Rendering takes ~48 secon...

Thanks

Collada import and server rendering

Hi all, I work on a project to render a scene which should be modified server side before rendering (server side too). I don't have many problems to rendering server side but I have many issues to modify the scene before rendering. It's very complex to modify a .blend file, so I prefer modify a coll...
