the CUDA_ARCH_BIN parameter specifies multiple architectures so as to support a variety of GPU boards. otherwise, cuda programs will not run with other type of GPU boards.
爲了支持在多個不一樣計算能力的GPU上運行可執行程序，opencv/caffe編譯過程當中須要支持多個不一樣架構，eg. CUDA_ARCH_BIN 3.0 3.5 5.0 5.2 6.0 6.1, 所以編譯過程很是耗時。在編譯的而過程當中儘量選擇須要發佈release版本的GPU架構進行配置編譯。

possible solutions

With BUILD_PERF_TESTS and BUILD_TESTS disabled, I managed to build OpenCV 3.1 with CUDA 8.0 on Windows 10 with VS2015 x64 arch target. Without building test/performance modules, the build process costs less time as well : )

I actually got it to work both on my laptop and my desktop (GTX960M and GTX970 respectively) running with OpenCV 3.2 and the latest version of CUDA 8.0 for Win10 in Visual Studio 15 Community! What I did was to enable WITH_CUBLAS aswell as WITH_CUDA. I also turned off BUILD_PERF_TESTS and BUILD_TESTS. The configuration was built using the Visual Studio 14 2015 C++ compiler.

my solution:

disable `BUILD_PERF_TESTS`

opencv disable build perf tests

configure and build again. this time cost only about 1 minutes.

after error fixed,build results
after errors fixed

cuda-module

OpenCV GPU module is written using CUDA, therefore it benefits from the CUDA ecosystem.

GPU modules includes class cv::cuda::GpuMat which is a primary container for data kept in GPU memory. It’s interface is very similar with cv::Mat, its CPU counterpart. All GPU functions receive GpuMat as input and output arguments. This allows to invoke several GPU algorithms without downloading data. GPU module API interface is also kept similar with CPU interface where possible. So developers who are familiar with Opencv on CPU could start using GPU straightaway.

The GPU module is designed as a host-level API. This means that if you have pre-compiled OpenCV GPU binaries, you are not required to have the CUDA Toolkit installed or write any extra code to make use of the GPU.

        dst.download(result_host);

cpu vs gpu time cost

  • (1)對於分辨率不特別大的圖片間的ORB特徵匹配，CPU運算得比GPU版的快（因爲圖像上傳到GPU消耗了時間）
  • (2)但對於分辨率較大的圖片，或者GPU比CPU好的機器（好比Nvidia Jetson系列），GPU版的ORB算法比CPU版的程序更高效。

problems

(1) 使用cuda版本的opencv caffe網絡的第一次建立很是耗時，後面的網絡建立則很是快。
(2) opencv的gpu代碼比cpu代碼慢，初次啓動多耗費20s左右。(事實是因爲編譯的caffe和GPU計算力不匹配致使的)

reasons

Your problem is that CUDA needs to initialize! And it will generally takes between serveral seconds

Why first function call is slow?
That is because of initialization overheads. On first GPU function call Cuda Runtime API is initialized implicitly.

The first gpu function call is always takes more time, because CUDA initialize context for device.
The following calls will be faster.

Not Reasons:

(1) CPU clockspeed is 10x faster than GPU clockspeed.

(2) memory transfer times between host (CPU) and device (GPU) (upload,downloa data)

runtime errors

gtx 1060 編譯的opencv caffe在gtx 970m上運行出現錯誤

im2col.cu Check failed: error == cudaSuccess (8 vs. 0) invalid device function

gtx 1060   sm_61
    gtx 970m   sm_52

im2col 是caffe的源文件，代表gtx 970m的計算能力不支持可執行文件的運行。

reasons

see what-is-the-purpose-of-using-multiple-arch-flags-in-nvidias-nvcc-compiler

Roughly speaking, the code compilation flow goes like this:

CUDA C/C++ device code source --> PTX --> SASS

The virtual architecture (e.g. compute_20, whatever is specified by -arch compute...) determines what type of PTX code will be generated. The additional switches (e.g. -code sm_21) determine what type of SASS code will be generated. SASS is actually executable object code for a GPU (machine language). An executable can contain multiple versions of SASS and/or PTX, and there is a runtime loader mechanism that will pick appropriate versions based on the GPU actually being used.

win7/win10 deploy

  • compile opencv caffe on windows 10 for GTX 1060
  • deoply on windows 7 for GTX 1080 Ti successfully

for win7, if we install 398.82-desktop-win8-win7-64bit-international-whql.exe,errors may occur:

> nvidia-smi.exe 
Failed to initialize NVML: Unknown error

Solutions: use older drivers 385.69

linux/window performance

(1) api在linux平均耗時3ms;一樣的代碼在windows平均耗時14ms

(2) vs編譯開啓代碼優化先後性能相差接近5倍，125ms vs 25ms

(3) cmake編譯RELEASE選項默認已經開啓了代碼優化 -O3
