Mandelbulber 1.21 OpenCL

[bartolomiew]

Hi all,

I'm really newbie with Mandelbulber and I'm trying to use it on Window 7 x64 16 Gb with an ATI Radeon 6770.
I've downloaded and installed lastest catalyst : 14-4-win7-win8-win8.1-64-dd-ccc-whql.exe
I've tested OpenCL with GPU_Caps_Viewer_1.20.1.1
But activating OpenCL in Mandelbulber results in a crash.
I'm working in a R&D department and a friend of mine help me telling that my OpenCL version is a newer and the culprit is the use of variable with the name 'half'.
So I've just find/replaced 'half' by '_half' in those files :
- cl_engine.cl
- cl_engine_fast.cl
- cl_engine_full.cl
- cl_engine_noDE.cl
and now I'm able to use OpenCL with Mandelbulder.
I hope this help even if my description is not accurate.

I experienced the same opencl 1.2 problem since amd catalyst driver 14.4 (13.2 works), both on 64bit Linux and Win7 platform :

Code:

OpenCL Build log:	"S:\TEMP\OCL4008T5.cl", line 427: error: invalid combination of type specifiers

  	half = normalize(half);

  	                                 ^

6 errors detected in the compilation of "S:\TEMP\OCL4008T5.cl".

Frontend phase failed compilation.

  for sharing this workaround !

Interesting, I got GPU caps viewer and confirmed openCL works fine... though I've never had it work in mandelbulber. So I tried the workaround, replaced "half" with "_half" in those files. Still not working

@Joe,

Your openCL build log is similar to what I get every time I run Mandelbulber 1.21 64bit on my laptop, where I can only run openCL  on device type CPU (as my GPU chipset software cannot be updated for  the openCL versions that can handle "float3").

Mandelbulber 64bit seems to by default try and run openCL on device type GPU,  fails, then displays the error. I close the OpenCL build log,  and on the openCL engine tab I "tick" openCL Enable,  Mandelbulber then finds the device type CPU and all works fine.

Note:
  - on the OpenCL Engine tab, the openCL Information states in my case GPU frequency and GPU memory instead of CPU.
  - i'm running an intel i3 CPU  on an AMD openCL platform.

Hope this is clear and helps

Hi all,

I'm really newbie with Mandelbulber and I'm trying to use it on Window 7 x64 16 Gb with an ATI Radeon 6770.
I've downloaded and installed lastest catalyst : 14-4-win7-win8-win8.1-64-dd-ccc-whql.exe
I've tested OpenCL with GPU_Caps_Viewer_1.20.1.1
But activating OpenCL in Mandelbulber results in a crash.
I'm working in a R&D department and a friend of mine help me telling that my OpenCL version is a newer and the culprit is the use of variable with the name 'half'.
So I've just find/replaced 'half' by '_half' in those files :
- cl_engine.cl
- cl_engine_fast.cl
- cl_engine_full.cl
- cl_engine_noDE.cl
and now I'm able to use OpenCL with Mandelbulder.
I hope this help even if my description is not accurate.

This worked for me.
AMD R9 280x, newest catalyst drivers (as of 7/19/2014)
