Upgrade instructions

From #4118 (Use single DataBox type in DistributedObject and MockDistributedObject):

• No longer use Actions::SetupDataBox in a phase action list. Setting up the DataBox is now handled by (Mock)DistributedObject
• ActionTesting::get_databox should only have a single template parameter (the component)

From #4093 (Automatically embed input source YAML in H5 output):

When spectre executables output HDF5 data, the input-file options provided will be automatically embedded as an attribute named InputSource.yaml. Use the script src/Options/Python/ExtractInputSourceYAMLFromH5.py to extract the embedded source input into a YAML-formatted text file.

From #4128 (Find AH quantities in grid frame):

After this change, binary black hole evolutions will observe apparent horizon quantities in the grid frame instead of the inertial frame.

From #4033 (Add a global enum class Phase):

If you have defined an enum class Phase in a metavariables, instead #include "Parallel/Phase.hpp" and replace the enum definition with using Phase = Parallel::Phase;

From #4046 (Use global phase to simplify some code):

• In a PhaseAction, the first template parameter should be removed.
• Also restrict phase names to those in Parallel::Phase

From #4044 (Interpolation without Interpolator ParallelComponent for time-dependent maps.):

No changes needed for the user, but anyone changing the interpolator code will see differences:

• intrp::Vars::PointInfoTag now has a different type.
• InterpolationTargetVarsFromElement and some of the functions in InterpolationTarget_detail now take different arguments.

From #4050 (Add ResourceInfo tags to DgElementArray and IntrpTarget):

If your executable has the DgElementArray parallel component, add in the following block to the input file

ResourceInfo:
  AvoidGlobalProc0: false

If your executable has at least one InterpolationTarget parallel component, add the following under the ResourceInfo block in the input file

  Singletons:
    TargetName:
      Proc: Auto
      Exclusive: false

From #4056 (Allow CCE singletons to be placed on specific cores):

If you have CCE in your executable, add the following block to your input file:

ResourceInfo:
  Singletons:
    CharacteristicEvolution:
      Proc: Auto
      Exclusive: false
    BoundaryComponentName:
      Proc: Auto
      Exclusive: false

where BoundaryComponentName is one of AnalyticWorldtubeBoundary, H5WorldtubeBoundary, or GhWorldtubeBoundary depending on what your boundary component is.

From #4023 (Remove CERROR, specialize error macros for compile time and runtime):

This requires updaying computing resources to use >= gcc-9 or >= clang-9

From #4055 (Finish transition to using Parallel::Phase):

• Always use Parallel::Phase as the type of a phase
• Do not specify a determine_next_phase member function for metavariables. Instead define the default_phase_order member variable

From #4086 (Consolidate generic parallel actions):

If you used any actions in the eliminated directories, you will need to update the appropriate include statement.
If you added any actions to those directories, move them into ParallelAlgorithms/Actions

From #4099 (Combine registration phases):

If you are using Parallel::Phase::RegisterWithObserver, instead use Parallel::Phase::Register

From #4107 (Turn on LTS in BBH):

If using the BBH executable, update the time stepping options to match those of the test input file.

From #3940 (Add check for currently open H5 objects before insert/get):

When inserting or geting an object in an H5 file, you must close_current_object() before you can get/insert a new object.

From #3963 (Alter CCE interface managers for new changes to interpolation):

Any usage of the GhInterfaceManagers will likely need to be reworked to account for the new interfaces.

If you want to test code that uses the WriteReductionDataRow action, follow the instructions in the Reduction Actions section of the ActionTesting documentation

From #3976 (Template parallel info functions on return type):

When using any parallel info functions (Parallel::my_node, etc...), you must specify the return type as a template parameter.

From #4001 (Consolidate lists of AH tags):

When making an InterpolationTargetTag for AH finding, use the type aliases defined in ApparentHorizons/HorizonAliases.hpp for the various lists of tags.

From #4015 (Add ability to place singletons on specific cores):

To be able to place a singleton on a specific core and specify that it should be exclusively on that core, add the Parallel::Tags::SingletonInfo tag to the initialization_tags of the singleton. To avoid placing singletons and Array-elements on the global zeroth core, add the Parallel::Tags::AvoidGlobalProc0 tag to the initialization_tags of any singleton or Array component in your executable.

From #4027 (Remove colons from control system measurement names):

From #3939 (Add type trait for component type):

If you need to know what chare type a parallel component is, a Group, Nodegroup, Singleton, Array, use the Parallel::is_group_v<Component>, Parallel::is_nodegroup_v<Component>, Parallel::is_singleton_v<Component>, Parallel::is_array_v<Component> type traits, respectively.

Upgrade instructions

From #3766 (Stop computing errors inside ObserveFields, remove ObserveErrorNorms):

If you use ObserveErrorNorms, this is now replaced by ObserveNorms with specifying Error(variable). For example,

ObserveNorms:
  TensorsToObserve:
    - Name: Error(Psi)
      NormType: L2Norm
      Components: Sum
    - Name: Error(Phi)
      NormType: L2Norm
      Components: Sum
    - Name: Error(Pi)
      NormType: L2Norm
      Components: Sum

When writing executables, follow the example in EvolveScalarWave to see how to replace ObserveErrorNorms by ObserveNorms.

From #3832 (Delete thin wrappers around blaze::DynamicVector/Matrix):

If you used DenseVector/Matrix replace them with blaze::DynamicVector/Matrix. Use the includes DataStructures/Dynamic{Vector,Matrix}.hpp if you need support for serialization, make_with_value or option-creation, or include <blaze/math/Dynamic{Vector,Matrix}.h> directly if you don't need those features.

From #3817 (Use quaternion rotation map in BinaryCompactObject domain creator):

When specifying input options for the BinaryCompactObject domain creator, replace

RotationAboutZAxisMap:
  InitialRotationAngle: 1.0
  InitialAngularVelocity: -0.5

with

RotationMap:
  InitialAngularVelocity: [0.0, 0.0, -0.5]

Note: The initial rotation angle is now always assumed to be zero and cannot be specified by the user.

From #3876 (Consolidate mutation of global cache into single function):

To mutate a mutable global cache tag Tag, use Parallel::mutate<Tag, Functor>(cache, args...) where cache is a reference to the local GlobalCache. This works in both the testing framework and charm-aware situations.

From #3882 (Omit BBH domain cube-to-sphere transition):

If you use the BinaryCompactObject domain, try setting EnvelopingCube.Sphericity = 1 and OuterShell.InnerRadius = Auto. This configuration transitions from the two inner objects to the outer spherical shell in a single layer of blocks, which can greatly improve the effectiveness of grid points in the domain.

From #3902 (post_horizon_find_callbacks is now a tmpl::list.):

post_horizon_find_callback needs to be changed to post_horizon_find_callbacks, and is
a tmpl::list of structs instead of a single struct.

From #3838 (Change ASSERT and ERROR to throw an exception instead of aborting):

If you have an ASSERTION_TEST or ERROR_TEST as a separate SPECTRE_TEST_CASE, they should be combined with the standard SPECTRE_TEST_CASE by calling CHECK_THROWS_WITH (see the Catch documentation for usage)

From #3712 (Update installation instructions, add Spack env file, upgrade container):

To compile the Doxygen documentation, upgrade to the recently released bugfix version 1.9.3. Earlier versions also work, but the documentation may not look the same as on https://spectre-code.org.

From #3720 (Disable IWYU by default):

To enable IWYU, set -D USE_IWYU=ON in your CMake config.

From #3715 (Allow experimental builds with Charm++ 7):

Builds with Charm++ 7 are now allowed, meaning the SpECTRE build system now accepts Charm++ 7 installations. Builds with Charm++ 7 are still experimental, so please file or fix issues you encounter.

From #2680 (Link Charm++ as a CMake target):

We link Charm++ like any other external dependency now. In particular:

• If you include <pup.h>, add Charmxx::pup to target_link_libraries.
• If you include <charm++.h>, add Charmxx::charmxx to target_link_libraries.

It is now easier to link Charm++ shared libraries, which can significantly reduce the size of builds. To take advantage of this, build Charm++ with the --build-shared flag and configure the SpECTRE build with -D BUILD_SHARED_LIBS=ON.
