Next time I will take another one ;-).
Hi, I just want to add my opencl performance data because it is significant. Especially with denoised profile. Five times faster with opencl. Running on a i7-2600K CPU @ 3.40GHz with GeForce GTX 750 TI: Without opencl I get: ===================== [dev_pixelpipe] took 0.000 secs (-0.000 CPU) initing base buffer [export] [dev_pixelpipe] took 0.029 secs (0.112 CPU) processed `let's go float!' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.026 secs (0.124 CPU) processed `white balance' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.019 secs (0.112 CPU) processed `highlight reconstruction' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.215 secs (1.144 CPU) processed `demosaic' on CPU, blended on CPU [export] [dev_pixelpipe] took 32.670 secs (222.948 CPU) processed `denoise (profiled)' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.113 secs (0.680 CPU) processed `base curve' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.139 secs (0.952 CPU) processed `input color profile' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.256 secs (1.624 CPU) processed `sharpen' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.165 secs (1.076 CPU) processed `output color profile' on CPU, blended on CPU [export] [dev_pixelpipe] took 0.056 secs (0.344 CPU) processed `gamma' on CPU, blended on CPU [export] [dev_process_export] pixel pipeline processing took 33.689 secs (229.116 CPU) But with opencl I get: ====================== [dev_pixelpipe] took 0.000 secs (0.000 CPU) initing base buffer [export] [dev_pixelpipe] took 0.024 secs (0.020 CPU) processed `let's go float!' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.008 secs (0.008 CPU) processed `white balance' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.008 secs (0.008 CPU) processed `highlight reconstruction' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.045 secs (0.036 CPU) processed `demosaic' on GPU, blended on GPU [export] [dev_pixelpipe] took 5.990 secs (4.888 CPU) processed `denoise (profiled)' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.020 secs (0.020 CPU) processed `base curve' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.025 secs (0.024 CPU) processed `input color profile' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.053 secs (0.044 CPU) processed `sharpen' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.027 secs (0.016 CPU) processed `output color profile' on GPU, blended on GPU [export] [dev_pixelpipe] took 0.189 secs (0.400 CPU) processed `gamma' on CPU, blended on CPU [export] [opencl_profiling] spent 0.0146 seconds in [Write Image (from host to device)] [opencl_profiling] spent 0.0071 seconds in letsgofloat_1ui [opencl_profiling] spent 0.0064 seconds in whitebalance_1f [opencl_profiling] spent 0.0063 seconds in highlights_1f [opencl_profiling] spent 0.0158 seconds in ppg_demosaic_green [opencl_profiling] spent 0.0250 seconds in ppg_demosaic_redblue [opencl_profiling] spent 0.0028 seconds in border_interpolate [opencl_profiling] spent 0.0119 seconds in denoiseprofile_precondition [opencl_profiling] spent 0.0053 seconds in denoiseprofile_init [opencl_profiling] spent 0.8217 seconds in denoiseprofile_dist [opencl_profiling] spent 0.8358 seconds in denoiseprofile_horiz [opencl_profiling] spent 1.6055 seconds in denoiseprofile_vert [opencl_profiling] spent 2.5643 seconds in denoiseprofile_accu [opencl_profiling] spent 0.0138 seconds in denoiseprofile_finish [opencl_profiling] spent 0.0179 seconds in basecurve [opencl_profiling] spent 0.0228 seconds in colorin_unbound [opencl_profiling] spent 0.0185 seconds in sharpen_hblur [opencl_profiling] spent 0.0164 seconds in sharpen_vblur [opencl_profiling] spent 0.0170 seconds in sharpen_mix [opencl_profiling] spent 0.0246 seconds in colorout [opencl_profiling] spent 0.1420 seconds in [Read Image (from device to host)] [opencl_profiling] spent 6.1955 seconds totally in command queue (with 0 events missing) [dev_process_export] pixel pipeline processing took 6.389 secs (5.464 CPU) Matthias ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
