mitch_de Posted February 18, 2012 Share Posted February 18, 2012 Hi, if you would try some OpenCL Benchmarks, like OceanWave it would be fine. I get not the correct OpenCL result with 10.8 DP1 + Nvidia 9600GT in OceanWave. Also Luxmark works but not correct results. For an first test you can use OceanWave: http://www.insanelym...5 Nvidia 9600 GT = 89 fps DL: OceanWave ML (10.8 only!)

Blah101 Posted February 18, 2012 Share Posted February 18, 2012 I have to fix my OpenCL before I test, then I will report back. Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1797613 Share on other sites More sharing options...
bergoulle Posted February 18, 2012 Share Posted February 18, 2012 With Oceanwave i m getting Failed to initialize OpenCL= mostly by OpenCL driver didnt know your gpu, like Fermi GTX.... which need to be patched TI I have an AMD ATI 6850.

mitch_de Posted February 18, 2012 Author Share Posted February 18, 2012 Thats not good and and other problem you find out. To be more easy , please try the small OCLinfo tool ( in terminal), should show at least 2 OpenCL devices : 1 CPU and 1 GPU. If only 1 CPU is shown, OpenCL on GPU wont work at all. That problem is different to my problem with wrong screen drawings. oclinfo.zip Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1797896 Share on other sites More sharing options...

mitch_de Posted February 19, 2012 Author Share Posted February 19, 2012 OK, that (OCLinfo log) shows that OpenCL is available but in usage (OpenCL code) it fails with an error. Apple will fix that soon / in next DPs i think. AMD made much more problems as Nvidia in the past with OpenCL, but Apple always fixed that later. I also found out that, many changes in th eOpenGL API maybe the reason for the display glitches (running OceanWave on my Nvidia), so its not only an OpenCL problem, main prob was OpenGL which i get fixed by recompling unetr Xcode 4.4 & 10.8 SDK. Will upload soon an 10.8 Version of OcenWace - but that will not help in case of your OpenCL initilize error.

Nanael Posted February 19, 2012 Share Posted February 19, 2012 so it's just that we can't test it but openCL is working, right? Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1798397 Share on other sites More sharing options...
flip360 Posted February 19, 2012 Share Posted February 19, 2012 i have two devices shown with the OpenCLinfo tool, 1 CPU one GPU in 10.8 DP1 on my notebook (specs in sig) Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1798435 Share on other sites More sharing options...
mitch_de Posted February 19, 2012 Author Share Posted February 19, 2012 so it's just that we can't test it but openCL is working, right? No - you can test it but it may fail even its enabled. OpenCL Enabled doesnt mean the newer 10.8 DP1 OpenCL drivers work correct. Also it may - in this stage of Dev Preview be very dependend from gpu type + gpu vendor. For example the new OceanWave ML (10.8) Version works on my 9600 GT, on an GTX 460 (listed OK in OCLinfo) not, fails in OpenCL init section.

mitch_de Posted February 20, 2012 Author Share Posted February 20, 2012 Even if the OCLInfo tool - also OpenCL code works, it may happen than more complex OpenCL code may fail - like in OceanWave. Maybe an bug in OpenCL or OceanWave may need code changes (from Apple) in deep. because Luxmark also make some problems it think OpenCL App need some code changes. Have someone else tried LuxMark V2.0 ? I would recommend, because we know OceanWave make much probs, to try Luxmark V2. Please compare the display of the scenes preview between gpu only and gpu + cpu. Should look 100% similar, otherwise, if the look very different, problem (like me). http://www.luxrender.net/wiki/LuxMark#Download Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1798665 Share on other sites More sharing options...

mitch_de Posted February 20, 2012 Author Share Posted February 20, 2012 Yep, even if you dondt get Init or Build errors , like me, Luxmark will fail running 10.8 cmf investigated: opencl works ootb on fermi , but apple seems to have removed the sm_20 code and hard setting it to 1.2 or 1.3 won't work either MEANS: luxmark and all other programs that want to use more complex opencl stuff (like local memory atomics) will fail. Thats the reason why less complex Code, like OCLInfo worked without any problem.

mitch_de Posted February 20, 2012 Author Share Posted February 20, 2012 Great - i got (old) GALAXIES (OpenCL!) bench compiled for 10.7 + 10.8 - works with my Nvidia 9600 GT.

mitch_de Posted February 20, 2012 Author Share Posted February 20, 2012 So just have to wait and see! Thx for your answer! Did you test already the new galaxies build with your AMD ? An GTX 460 got 421 Gigaflops with 10.8 - so at least some gpus (beside me) can do galaxies.

mitch_de Posted February 20, 2012 Author Share Posted February 20, 2012 63 GigaFlops ? I get 114 GFlops with 9600 GT, Which GPU? Perhaps some AGPM problem (gpu wont run at max MHz).

Nanael Posted February 20, 2012 Share Posted February 20, 2012 It's a hd6870 O.o with 1024mo ram ^^ under lion i got 616Gflops at the end xD Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1798853 Share on other sites More sharing options...
mitch_de Posted February 20, 2012 Author Share Posted February 20, 2012 Wow, much downgrade in speed for your 6870 , 616 Gflops 10.7 > 61 Gflops 10.8 My 9600 GT also went down, but less than 10%. But 616 GFlops are great! Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1798901 Share on other sites More sharing options...
Nanael Posted February 20, 2012 Share Posted February 20, 2012 yes that's a lot ^^ at the beginning of the test I was thinking that more than 200 was impossible xD I have all reinstalled and i'll try again in a few mn. I'll let you know the results =) edit: so i got 555 =) Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1798911 Share on other sites More sharing options...
mitch_de Posted February 21, 2012 Author Share Posted February 21, 2012 555 with 10.8 ? That looks OK (even aso a bit slower than witn 10.7) Link to comment https://www.insanelymac.com/forum/topic/276053-opencl-problems-working-lion/#findComment-1799025 Share on other sites More sharing options...
