CUDA C/C++ is implementing these with inlined assembly.

@wsmoses and I had a good benchmark for this in https://github.com/wsmoses/Enzyme-GPU-Tests/tree/main/DG/cuda the reverse code performance notably worse on CUDA.jl then on AMDGPU.jl

Compat.jl would be nice, but I agree with Tim. We should add this to Base

Ah okay the `hwloc` case makes sense, but sadly this is also true for `flux start`: ``` lstat("/workspace", 0x7ffc96995c90) = -1 ENOENT (No such file or directory) brk(0x97c000) = 0x97c000...

Hm either a environment variable, or a configure option that forces everything to be relative would be fine with me. From https://www.gnu.org/prep/standards/html_node/Directory-Variables.html it seems that all options should be relative...

Thanks! Happy to jump on a call as well. Re `flux start` after fixing the environment variables ``` 2021-02-10T03:55:41.955681Z broker.err[0]: rc1.0: fish: Unknown command: /workspace/destdir/etc/flux/rc1 2021-02-10T03:55:41.955706Z broker.err[0]: rc1.0: fish: 2021-02-10T03:55:41.955717Z...

I can add Python into the mix, but I wanted to avoid it since it also looks like we need Python packages. Testing is one use-case, but for CESMIX I...
