The pcluster image has am internal buildcache without an index.
Also, we need to force reuse to avoid rebuilding GCC, since the default is
to only reuse dependencies - and that is subject to changes in the GCC
recipe.
* [pcluster pipeline] Use local buildcache instead of upstream spack
Spack currently does not relocate compiler references from upstream spack
installations. When using a buildcache we don't need an upstream spack.
* gcc needs to be installed via postinstall to get correct deps
* quantum-espresso@gcc@12.3.0 returns ICE on neoverse_{n,v}1
* Force gitlab to pull the new container
* Revert "Force gitlab to pull the new container"
This reverts commit 3af5f4cd88.
Seems the gitlab version does not yet support "pull_policy" in .gitlab-ci.yml
* Gitlab keeps picking up wrong container. Renaming
* Update containers once more after failed build
Add aws-plcuster[-aarch64] stacks. These stacks build packages defined in
https://github.com/spack/spack-configs/tree/main/AWS/parallelcluster
They use a custom container from https://github.com/spack/gitlab-runners which
includes necessary ParallelCluster software to link and build as well as an
upstream spack installation with current GCC and dependencies.
Intel and ARM software is installed and used during the build stage but removed
from the buildcache before the signing stage.
Files `configs/linux/{arch}/ci.yaml` select the necessary providers in order to
build for specific architectures (icelake, skylake, neoverse_{n,v}1).
