[Gate-users] GPU accelation problem

[이호연]

Thanks a lot Camille.I think my gpu's compute capability is not one of 20 or 30, I should check that and change the CMakeList.txtI feel like that will work!Thanks again-Hoyeon

   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
