Compiling with modern Linux / CUDA: -arch option

[chateauferret]

On running the Linux build script for cpu+cuda I got an error to the effect that "compute_30" wasn't recognised. Seemingly this has to do with specifying a minimum architecture which is now obsolete and should be met by any modern GPU / CUDA version. I just deleted the option in the compile script and it built and ran fine. Note that the compile options are also set to terse, so there will be no output during the compile, which takes a couple of minutes; please be patient (or set it to verbose).

Thanks for sharing a solution. Removing '-arch compute_30' let me install on Google Colab.

I used -arch compute_50 with CUDA 11
