- use cudaPackages instead of cudatoolkit (reduces download/closure size) - set C/C++ compiler when building with CUDA to ensure NVCC has an appropriate backing compiler - add flag to build with CUDNN (disabled by default due to increase in closure size) - add flag to build with LTO (enabled by default)

Hi all, Are there any blockers preventing this from being merged? |

LGTM, @basvandijk @SomeoneSerge thoughts? |
| # Only clang supports thin LTO, so we must either be using clang through the stdenv, | ||
| stdenv.cc.isClang || | ||
| # or through the backend stdenv. | ||
| (enableCuda && backendStdenv.cc.isClang) |
There was a problem hiding this comment.
