(Question) Mandelbulber and default settings file
« on: November 25, 2018, 07:15:14 PM »
Hi. I builded the new version for Linux: 2.15. Since it is OpenCl oriented its camera rendering is at "full" concerning OpenCl, for those who make it with the OpenCl precompiler. I tested the CPU build and the camera rendering works correctly. My problem is that the OpenCl build needs to have the GPU as rendering engine in the "Program Preferences". I choose one GPU, as you see in the attached picture. After that setting the rendering is perfectly done!!! So there are not problem around the BUILD. My problem is the Program Preferences file. After the Mandelbulber shutdowns this setting flyes away! I need to FIX it in a file. But: what is the file? Please could you suggest where the parameters file is? Thanks.

Preferences file is located in ~/mandelbulber/.mandelbulber_215.ini (note: there are two directories: mandelbulber and .mandelbulber)

Hi, and thanks for your help. I found some rows about OpenCL:

Code: [Select]
opencl_device_list 8b4005;
opencl_device_type gpu;
opencl_disable_build_cache false;
opencl_enabled true;
opencl_memory_limit 1900;
opencl_mode full;
opencl_platform 2;
opencl_precision single;
opencl_use_fast_relaxed_math true;

The "platform" row was "0". I tryed both value 1 and 2. At startup Mandelbulber goes in OpenCl error: [Error: No devices to use for OpenCL! Check program preferences.] I must choose the card before start to work. Not bad, the most important thing is the rendering, and it works. But I would learn. Many thanks friend, thanks for this wondelful work! I love it very mutch!!! Thanks!
