Hello All,
Did not see this post before updating to cuda-toolkit-11.4
I am seeing very much similar behavior to the above....this is just a grid once as a code test...
OS = 1.25, KW = 2.5 using same dcf
It seems like rolling back to cuda-10-2 is the current solution. If anybody working on this I can provide more details, or please share any update you may have found!
thanks!

cuda 10.2 .................................................... cuda 11.4

Thanks for the info. I will have a look on it.

Hi,
I just tried to compile the code on Ubuntu 18.04 with CUDA 11.2 and getting some errors in the compilation step. @samr96 what changes did you make to get it to compile?

Hi Emil @emilljungberg,
I just installed CUDA 10.2 and compiled with that, then everything worked. I think you can have multiple versions of CUDA installed on your machine.
Though there might be a way to make it work with CUDA 11 on Ubuntu, because it was the Win10 Visual Studio 13 dependency that made things go wrong for me. If you really want to use CUDA 11, you could try removing the GPU architectures which have been deprecated in CUDA 11 from the CMakeLists.txt file (so sm_30). Good luck!

Hi @emilljungberg @samr96
Could you provide some details about the package versions in Linux? for example, the GCC version? I tried to modify sm_20 into sm_60 for cuda 10, but it still didn't work. The error massage showed the C++ code error.
Thanks,

Hi everybody,
I have a similar behavior of the gpuNUFFT toolbox. If someone as a fix , do hesitate to answer to this post. Both cudatoolkit were installed and I modified the bashrc to link to the desired cuda version.
The code was running on Ubuntu 20.04
with gcc (Ubuntu 7.5.0-6ubuntu2) 7.5.0 for the compilation
and Matlab R2020b for testing the code
the line to be removed in theCMake for the compilation is below:
- set(MY_NVCC_FLAGS -arch=sm_30 -gencode arch=compute_30,code=sm_30)
Thanks in advance,
Best,

Sorry for my late response. As I'm currently not having access to a CUDA 11 capable card it's hard for me to fix it.
I hope someone finds a fix - PR welcome!
Best regards,

The issue unfortunately still persists with cuda 11.5 and 11.6. For me, it works until cuda 11.1.
