I'm consistently seeing: ``` Time (mean ± σ): 289.0 ms ± 7.6 ms [User: 243.0 ms, System: 862.1 ms] Range (min … max): 280.8 ms … 299.9 ms 10 runs...

Make `--enable-wrapper-rpath --disable-wrapper-runpath` pass `-Wl,--disable-new-dtags` when supported

3

Using OpenMPI 4.1.4, I would expect that the following configuration ``` --enable-wrapper-rpath --disable-wrapper-runpath ``` would imply `-Wl,--disable-new-dtags` when invoking `mpicc`. That is, force RPATH, instead of relying on compiler defaults....

### Describe the bug When compiling ucx with NVHPC compilers v22.3, and using mlx5_0:1, ucx_perftest hangs, and when `^C`'ing, the server triggers an assertion. The exact same setup with GCC...

Using mpich 3.4.3, libfabric 1.14.0, ch4:ofi:gni, I'm getting an issue similar to #4720. mpichversion: ``` $ ../view/bin/mpichversion MPICH Version: 3.4.3 MPICH Release date: Thu Dec 16 11:20:57 CST 2021 MPICH...

`HIP_CLANG_INCLUDE_PATH` shouldn't be found from `../llvm/...` path

This logic: https://github.com/ROCm-Developer-Tools/HIP/blob/1f53fbea8f52c76c9f9901f03b08d64f106ef098/hip-lang-config.cmake.in#L75-L79 doesn't work in Spack when clang is installed elsewhere. Since CMake 3.21 identifies the compiler as ROCMClang now, can't you just get this path from CMAKE_HIP_COMPILER and...

Spack likes to traverse spec graphs depth-first, but breadth-first would be more accurate to resolve conflicts in a sensible way. Consider a graph ``` A ├── B │ └── C...
