[Gate-users] GPU accelation problem

[Camille Metz]

Hi Hoyeon,


I had the same problem and fixed it by adding '-gencode arch=compute_XX, code=sm_XX;' on l.192 of CMakeLists.txt after CUDA_NVCC_FLAGS (and recompiled afterwards), where XX is the compute capability of your GPU card. Mine was not already taken into account (there is only 20 and 30). I don't know if this will solve your problem, but if your compute capability is different from 20 and 30, that may be worth a try!


Good luck with it,

Camille

Hello,

I tried to accelate the computed tomography imaging in GATE.

But the output of the main-gpu.mac in example_GPU directory gives blank output after the phantom with GpuTransTomo actor.

I think some others have similar problem, but no one answered the questions.

Is there any one successfully obtained result image with the example code?
Or do I need to modify some part of the code to get right result?

Thanks in advance
