Installation in Windows 11 / Matlab 2021 about gpunufft

[athertya]

When I tried the generate in cmake - I obtained .sln files , but failed at Visual studio build. Please find my output and error.

Any insight will be much appreciated!

Hey @athertya , I have not used the windows version,
But as far as I am aware, only visual studio creates the sln files and not cmake-gui.
I can see the error under code C1189 that you have a version mismatch issue.
Maybe change the version of visual studio as specified, or add the argument as asked to prevent the check for version as asked (-allow-unsupported-compiler) in the CUDA/CMakeLists.txt file for the NVCC flags

Hello Chaithya,
I added the argument for NVCC flags. I was able to build successfully. However, the "build" says 6 succeeded, rather than 9, as shown in the video?
I was able to run the matlab code using "useGPU=true", but not when the flag is false. Is it because the build was successful only for 6 instances?
Thanks for you help again!

Regards,
Jiyo

That's wonderful!
So you got the GPU version up and running. The CPU version mostly needs additional flags to work right. Do you need it? If not I think the GPU versions are much faster and better anyway.

I was missing Fessler's nufft package for CPU. Now it runs completely fine. Huge thanks to you.
But I'm just worried that the video shows 9 builds as success while I only have 6! hope it doesn't affect my recon.

I think some build has redued over time. Dont worry, things are working fine for you right? Also I dont see any build errors and anything missing. Any other feature just needs to be enabled as needed. But for now, I think you are good to go. @athertya / @andyschwarzl we can close this issue now. Please repopen if you still face the issue
