CUDA detection not working Windows 10

[nicolasdp88]

I successfully compiled cctag from the develop branch.

Dependencies are from vcpkg, with a slight patch to fix Boost constexpr issues.

CCTag develop is configured like this :

cmake -DCMAKE_TOOLCHAIN_FILE="[..]/vcpkg.cmake" -DCCTAG_ENABLE_SIMD_AVX2=ON -DBUILD_SHARED_LIBS=ON -DCCTAG_WITH_CUDA=ON -DCCTAG_CUDA_CC_CURRENT_ONLY=ON ..

It compiles fine in Release.

When running detection.exe on the samples, I get the expected result using CPU, but as soon as I use CUDA I get no candidates detected.

`Creating TagPipe 0 Initializing TagPipe 0 Loading image 0 into TagPipe 0 Total time: 0.228465s wall, 0.093750s user + 0.125000s system = 0.218750s CPU (95.7%)

RTX3070, if it changes anything.

I observe the same behavior using the exact same version as you (CUDA and boost) except that I have a Quadro P1000.

Hi,

I have the same issue, but running on Ubuntu. When detection script is running on CPU everything is OK, detect the candidates, but when is running on GPU I have zero detected candidates.

Did you solved this?

Thank you!

Thank you!

Which card do you have?

Hi, Nvidia GTX 1050 TI

I did a clean install and now I'm getting the same on the 1080. Clearly something went really wrong after fixing the CPU-side code. I'm afraid figuring it out will take a while :-(

[cristian893]

Is there older release or older version that I could try to run on GPU?

Thank you!

Hello all!

First time playing with CUDA, but I've got this thing working.

@griwodz Problem was that it was using too many threads per block when launching vote::eval_chosen in frame_07c_eval.cu.

Made the block size 24 and all works as expected.

@simogasp How can I submit a patch for this? Not much of a github contributor either...

What did you changed exactly to fix the issue? I was trying to reproduce your fix but I can't figure out exactly where you changed what.

you can post here an extract of the code that you changed.

Sorry I did not see this sooner. Here is what I patched

@nicolasdp88 I have changed the code according to CUDa patch.txt, but still can't detect it. May I ask where is the problem? Can you give me the EXE you compiled
