I need more time to investigate the problem but now is much better.
Here there is a mini test made with OSX-mandelbulber using OpenCL  grin  A Beer Cup

Today I have released Mandelbulber 1.17-2 which include some bugfixes for OpenCL engine:

- fixed bug: OpenCL - include path compatible with nVidia-win32 driver requirements (no "/")
- fixed bug: OpenCL - changed all M_PI to M_PI_F - there were problems with compilation kernel code on some machines
- fixed bug: OpenCL - some frames of animation were incomplete
- fixed bug: OpenCL - removed #pragma OPENCL EXTENSION cl_khr_byte_addressable_store : enable
- fixed bug: on Arch Linux there was problem with missing system includes

As always newest version is here: http://sourceforge.net/projects/mandelbulber/

Please let me know if there is still something wrong

Hi
Thanks for your fantastic program.
I have problems rendering using OpenCL.
Whenever I enable OpenCL and click the Render button, it crashes.

Thanks for your fantastic program.
I have problems rendering using OpenCL.
Whenever I enable OpenCL and click the Render button, it crashes.

It crashed because you had to lees graphics memory available (Max memory allocation: 134217728). The program needs about 300MB of graphics memory to work with optimal OpenCL queue size (buffers for reflections take a lot).

You are correct, but my device has 1024MB of dedicated memory, then why OpenCL only uses 128MB of it?
Is there any way to force OpenCL to use all available memory?

Update:
I found this on AMD Developer forums:
To use all available memory, some variables should be modified:
GPU_MAX_HEAP_SIZE
GPU_MAX_ALLOC_SIZE

for example in a shell:
export GPU_MAX_HEAP_SIZE=100
export GPU_MAX_ALLOC_SIZE=100
mandelbulber-opencl

or put it in the ".bash_profile" of home directory

Also if the 100 did not work, maybe 99 or some less value do the work.

Oh wow, a new version.
Thanks very much Buddhi. smiley

Just one thing, and please forgive me if I'm being completely thick, but I can't seem to find the "OpenCL Enable" checkbox (although I can see the HDR one just fine).

I'm running a nVidia GTX 550 ti, which I'm told has OpenCL support, but maybe it's become greyed out or something for some reason. Which tab would it be found on under normal conditions?

Thanks very much in advance.

I had the same prob in the beginning. Take a look on your program folder. There are two executables - one classic and one opencl version. You might assume, only the opencl version has the opencl tab...  wink

Aha! Found it! Thank you very much. smiley

Unfortunately, it dumps me back to the desktop when I enable it, but I've only just this minute walked in.
I'll update my drivers and stuff, and see if I can get to the root of the problem.

Thanks very much for the pointer though. smiley

Under Windows in Start menu you have two items: Mandelbulber and Mandelbulber OpenCL.


Unfortunately, it dumps me back to the desktop when I enable it, but I've only just this minute walked in.

When you start the program from command line you will see more information what is wrong.

Hi Buddhi, thanks for the reply.

Ok, I've tried it from the command line, and it gives me several lines of stats that look pretty generic (although I'm happy to provide these if it will help), but the lines that look important are these.

Code:
OpenCL Build log:       Error in processing command line: Don't understand command line argument "Files\Mandelbulber\cl"
"!
ERROR: Program::build() (-11)

(btw, these lines don't appear until I try to enable the OpenCL checkbox and the program exits, if that's any help).

Anyway, any ideas you might have would be very much appreciated, but I'm still hopelessly in love with this program even without the OpenCL stuff. smiley

Which version are you trying to run? 1.17 or 1.17-2? I fought that this problem is already fixed. I added double quotes in the code to avoid such a problem. It looks like the OpenCL driver still can't load files from application folder where the folder path contains spaces (like "Program files"). What is strange this problem is only with nVidia drivers (I suppose that you have nVidia gfx card).
Temporary to run the application you can move Mandelbulber program folder it to some place where there are no spaces in the path.

I've got the program updated to 1.17-2, so I don't think that's the problem, and yes, it's a nVidia 550 ti in my machine (Windows 7 32bit).

Anyway, the program was in a folder with spaces (Program Files, funnily enough), so I copied the Mandelbulber folder to the root of the drive.

I'm afraid it still didn't seem to work, but this time, I got a slightly different error.

I'll include the more generic lines this time, just in case it helps.

Code:
OpenCL Platform number is: 1
OpenCL Platform is by: NVIDIA Corporation
OpenCL contexts created
OpenCL Number of compute units: 4
OpenCL Max work item dimmensions: 3
OpenCL Max work group size: 1024
OpenCL Max clock frequency  1800 MHz
OpenCL Memory size  0 MB
OpenCL Max constant buffer size  0 kB
OpenCL Constant buffer used  1 kB
OpenCL Number of loaded sources 7
OpenCL Build log:       :9:10: fatal error: 'mandelbulber_cl_data.h' file not found
#include "mandelbulber_cl_data.h"
         ^

ERROR: Program::build() (-11)

Is there any other information I can provide that might help?

Now I'm completely don't know why it can't find 'mandelbulber_cl_data.h' file. Because I don't have computer with Windows and nVidia gfx card (I have ATI), I can't reproduce this error on my computer and I need to know where OpenCL library tries to find this file. But I have some idea how to do some diagnostic of the problem.
You have to do something for me.
1. Download "Process Monitor" from http://technet.microsoft.com/pl-pl/sysinternals/bb896645.aspx
2. Launch Mandelbulber OpenCL
3. launch Process Monitor
4. Set filter (menu Filter/Filter...) as it is showed on attached image. (Process Name | is | mandelbulber-opencl.exe | then | Include) and click Add and OK
5. Enable OpenCL in Mandelbulber
6. Look at output in Process Monitor window and try to find some reference for 'mandelbulber_cl_data.h'. It should look like on second attached image. The most interesting for me are events where result is "NAME NOT FOUND". Please do screenshot and send me.

I hope this will tell me more.

The only way I could get Mandelbulber to run on my Nvidia card, was by hardcoding the path of the "mandelbulber_cl_data.h" in the OpenCL code.

I've attached the Process Monitor dump for my system. I installed Mandelbulber in "E:\Mandelbulber", and in the console the parameter -I"E:\Mandelbulb/cl" is passed to the Nvidia compiler.
