Re: What's wrong with this file?

Hi Gtype,

I may just be in a position to test a fix. I will keep this thread posted if something interesting turns up...

Meanwhile, Thanks a lot for the support and patience. We understand this is a bit frustrating....

Hopefully, a fix is just round the corner...

Re: What's wrong with this file?

Hi i know swap is system thing. I just don't use swap on my system as I have 32GIGs of RAM. When Linux finds out it is out of memory then OOM killer kicks in and kills process that is using most of RAM (in this case AMD opencl compiler). As on my system it was using 31 GIGs of RAM so i had to close all other apps so I have enough memory.

Anyway since update to latest stable linux driver from amd website it crashes anyway so basiclly with new driver it is not working at all.

I will investigate more when I am back on my main workstation pc as i travel a lot

Re: What's wrong with this file?

Hello,

I believe the problem occurs due to limitations in the current driver from AMD because the Blender Cycles render using Nvidia OpenCL almost as well as CUDA.

AMD really need fix this as developer of LuxRender found similar issue when he implemented recursive procedural materials into LuxRender.

Re: What's wrong with this file?

Nou,

As far as Nazim's steps to repro, the initial test on the fix-driver has been successful - at least no crash.
I will need some more time before I can fully commit on this.

At the same time, for the 30GB memory gulp issue - I would like to test this with the blend file you had posted.

However, I am unable to download the mikepan blend file.

Can you post it here? It will be useful to test further.

Also, if you could just post the steps to reproduce with the blend file, it will be useful.

Thanks for your time on this,
