Hi Graham, CUDA 11.1.0 just got accepted into experimental. Don't upload that to Ubuntu, wait for 11.1.1 with the CVE fix. But some testing would be nice anyeway ;-) Expecially of the try-gcc-10-clang-10 branch - https://gist.github.com/ax3l/9489132 says that both 10 versions are now supported. Andreas
