なにやらnvoptix.dllの発見にEC2インスタンスの環境だと失敗しているらしく
C:\Windows\System32\DriverStore\FileRepository\nv_dispw〜
から
C:\Windows\System32
にnvrtum64.dllとnvoptix.dllをコピーすると動作しました。
RTX ONです。

.cu を .ptx にコンパイルしていない場合は、以下の .h を全部 cuda/ にコピーしないと .cu のコンパイルが通りませんでした。

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\include
C:\ProgramData\NVIDIA Corporation\OptiX SDK 6.0.0\include
