--reuse concretizes to a new architecture than the current target architecture #29672
Description
Steps to reproduce
On a Power8 system I can create an environment that then fails to build because it tries to use Power9 installed packages.
spack env create lbann-gitlab-power8le
spack env activate -p lbann-gitlab-power8le
spack compiler find --scope env:lbann-gitlab-power8le
spack external find --scope env:lbann-gitlab-power8le bzip2 cmake cuda cudnn hipblas hwloc ninja libtool nccl ncurses openssl perl pkg-config python rccl rdma-core sqlite spectrum-mpi mvapich2 openmpi
spack add lbann@gitlab-power8le +gold cuda_arch=60 +cuda +deterministic +vision +numpy ^hydrogen@develop blas=openblas ^dihydrogen@develop blas=openblas ^aluminum@master ^spectrum-mpi ^[email protected] threads=openmp ^[email protected] ^[email protected] ^[email protected]
spack develop --no-clone -p /usr/WS1/vanessen/lbann_bugfixes.git lbann@gitlab-power8le
spack add [email protected]:
spack concretize --reuse --test root
spack concretize -f --reuse --test root
Error message
On a system where there is a an existing power9le set of software packages the above commands when using --reuse find packages that are incompatible with the power8le architecture.
