SCR moved to a component version some time ago, but never had a
release associated with these changes. SCR v2 is a legacy version
that is no longer being developed/supported. In preparation for an
upcoming SCR v3 release, there is now a 3.0rc1 release available to
users.
This adds the 3.0rc1 release to the spack package and deprecates the
older versions.
Additional changes include:
- Enforce using the main branches of the components when installing
scr@develop
- Enforce SCR v3 uses at least the recently released versions of each
of the components
- Use a simple `detect_scheduler()` function in an attempt to be
smarter about setting the default resource manager and not require
users to always manually provide the variant
- Add/update variants that were recently added to AXL and KVTree
components
- Fix cmake arg naming bug of setting `SCR_CONFIG_FILE`
- `SCR_ASYNC_API` is now being handled by a component and is only
needed by the legacy versions.
