Huge thanks for the PR to fix this!
Random question: you mentioned over on the GPU MODE Discord that you were running this on V100, did you encounter any issues building Mojo code for that GPU? We only recently were able to lower the floor for GPU support to Turing (sm_75), so I’m surprised that this worked for you on Volta (sm_70). Did you have to hack anything in your Mojo standard library to get that to work for you?
