Add CUDA & OpenCL support#227
Conversation
cuDiffmapOpsinDynamicsImage cuComputeBlockZeroingOrder cuMask
继续简化代码
目前速度比opencl略差，待分析优化
肯定是opencl生成代码时有bug!

I'm having trouble building OpenCL only with the Intel SDK, this seems to be part of it.

Try OpenCL 2.0 or larger version in OpenCL Code Builder setting.
|
Any news on this? |

| You can pass a `--c` parameter to enable the procedure optimization or `--cuda` parameter to use the CUDA acceleration or `--opencl` to use the OpenCL acceleration. | ||

Maybe create a dropbox email like guetzli-support@tencent.com that would go to all 3 of you (and could be adjusted on your end to add/remove people as necessary without having to update these docs)

Could someone of you provide a working binary file for windows with cuda support? This would be awesome. |
|
Will this require non-free CUDA (cuda.h) libraries for compilation? If yes, probably a compilation flag is needed to disable them... |
|
where is cu_mem defined? cuda or opencl can not find that. |
|
@leafjungle It's defined in clguetzli.cl.h, not an original CUDA definition. |
|
which GPU was used in your environment? |
|
Waiting impatiently for this to be merged )) |
|
Yes, we all do! |

Is this ever going to be merged ? :) |
|
Any update on this? Please :) |
|
Did anyone ever succeed in building those binaries and want to share them? ;-) |
|
This looks incredible! @crazyks could you resolve the conflicts, update the dependencies and rebase? I will check with someone from Google if we can merge into master. If not, we can create a fork. |
|
Hi there. I have built Guetzli with CUDA for Windows. You can download binaries from here. |

@crazyks could you resolve the conflict? |

Guetzli is an awesome jpeg encoder, however, it works a liitle bit slow. In order to speed it up, we have added CUDA & OpenCL support for Guetzli and we also optimized some procedure and added full jpeg format support.
This work is made by strongtu, ianhuang, tongzhan and me.
We had it tested on our GPU server, and here is the test statistical data for one of the sample pictures.
We hope that our codes can be merged into guetzli/master branch:)
