OSX Multibeam OpenCL question

[Raistmer]

All variants should build OK actually.
I'll check what is regarding NV. MultiBeam OpenCL NV rarely used (for windows and Linux we have CUDA version that faster) so OPENCL_NV define there could be little unmaintained.
Regarding USE_OPENCL_HD5xxx - that's for ATi cards. And should be used together with USE_OPENCL as addition.
What errors do you see for this build ?

[Joe Fox]

Attached is the stderr.txt. Let me know if you need additional info. It was built using the same build flags and preprocessor flags as the intel version that works. The only difference is USE_OPENCL_HD5xxx instead of USE_OPENCL_INTEL.

[Raistmer]

Thanks.
-43 is CL_INVALID_BUILD_OPTIONS error. Some compiler option not go it seems.

I'll look closer on weekend probably.

[Urs Echternacht]

These are the buildoptions for OpenCL compiler when HD5xxx is active (which has no specification for __APPLE__ yet) :
#elif USE_OPENCL_HD5xxx
      strcpy(buildoptions,"-w -DRESULT_SIZE=32 -cl-unsafe-math-optimizations -DUSE_OPENCL_HD5xxx -fno-bin-amdil");

Joe, could you try a rebuild using this options in src/GPU_lock.cpp instead :
#elif USE_OPENCL_HD5xxx
#if __APPLE__
      strcpy(buildoptions,"-w -D__APPLE__ -DRESULT_SIZE=32 -cl-unsafe-math-optimizations -DUSE_OPENCL_HD5xxx");
#else
      strcpy(buildoptions,"-w -DRESULT_SIZE=32 -cl-unsafe-math-optimizations -DUSE_OPENCL_HD5xxx -fno-bin-amdil");
#endif

Hi Urs,

I applied the change that you suggested. I now get error -49 instead of -43. Attached is the stderr.txt

[Raistmer]

Please check that we on the same build path for HD5 build:

OCL_ZERO_COPY;OCL_CHIRP3;ATI_OS_WIN;SETI7;USE_OPENCL_HD5xxx;USE_OPENCL;USE_SSE;NDEBUG;_WINDOWS;CLIENT;_CONSOLE;USE_I386_OPTIMIZATIONS;USE_I386_XEON;USE_AMD;USE_FFTW

these deifnes (except windows-specific of course) should be set for HD5 build.

[Joe Fox]

The only one that I see which we aren't using us USE_AMD. I will add that and try again.

[Raistmer]

try to go clFFT_ExecuteInterleaved_mb functionand add OCL_LOG_ERR("smth"); after each kernel argument set.
Like:
         err |= clSetKernelArg(kernelInfo->kernel, 0, sizeof(cl_mem), &memObj[currRead]);OCL_LOG_ERR("arg 1");

that way we will know what argument fails .

[Raistmer]

So, what was outcome?

[Joe Fox]

Sorry, I have been on the road for the last week and haven't had a chance to follow up. I'll be able to add the debug code and narrow down the troublesome parameter this week.

Thanks

[Raistmer]

Great! Will wait with interest (and I'm not always available too so no problems, lets catch each other ).

EDIT: With AP tasks too scarse the need for these builds is great and increases constantly. Share your efforts and issues please, we need to make some breakthrough on this front.

[Joe Fox]

Understood. I finally have the build modified with the debug info. As soon as I get access to my nvidia and ATI/AMD based machines, I'll run the tests. Should be within the next day or two.

Interestingly, the intel targeted build worked on all three machines, and appeared to be using the GPU based on the time it took for the test to run.

Thanks for the patience.

Here is the final output before I get the error. This is running the HD5xxx version on a mac pro with two ATI/AMD GPUs

The full stderr.txt is attached as well.

I will be testing the nvidia one this evening.
Thanks

[Raistmer]

-49 is invalid argument index.

Please check arguments for that last call (clSetKernelArg).

Try to update your workspace with latest rev also. Seems Urs can build OpenCL ATi for OS X w/o issues now. Only issue we working on is one missed pulse in special test task, but not any runtime errors...

[Joe Fox]

The latest call is

err = clSetKernelArg(CalcChirpData_kernel2_cl,0,sizeof(cl_float2),(void *)&chirprate2)

I will examine what the values of chirprate2 are.

I will also grab the latest code and see if the issue persists.

Thanks
