For Change Control Board: Change Request Review

The following review must be completed by an authorized member of the Change Control Board.

• 1. Review all computer code.
• 2. If any changes occur to the input syntax, there must be an accompanying change to the user manual and xsd schema. If the input syntax change deprecates existing input files, a conversion script needs to be added (see Conversion Scripts).
• 3. Make sure the Python code and commenting standards are respected (camelBack, etc.) - See on the wiki for details.
• 4. Automated Tests should pass.
• 5. If significant functionality is added, there must be tests added to check this. Tests should cover all possible options. Multiple short tests are preferred over one large tes.
• 6. If the change modifies or adds a requirement or a requirement based test case, the Change Control Board's Chair or designee also needs to approve the change. The requirements and the requirements test shall be in sync.
• 7. The merge request must reference an issue. If the issue is closed, the issue close checklist shall be done.
• 8. If an analytic test is changed/added, the the analytic documentation must be updated/added.

Requires idaholab/raven#1994

I found that this method gets called repeatedly in the DispatchManager.py for each ARMA realization. I was able to reduce quite a significant amount of memory consumption by memoizing this function. Instead of making a whole new PR, it might be worth to just add here. All you need to do is:

at the top in the imports:

from functools import cache

and then add the decorator to the function:

@cache
get_synthhist_structure

[PaulTalbot-INL]

ohhh, because RAVEN runs this each time instead of once ever ... maybe Mohammad's work will fix this to some degree. Good catch.

Does cacheing fix this if parallelized?

[joshua-cogliati-inl]

Thanks, fixed: 764ce1c

[joshua-cogliati-inl]

I am pretty should this cache is per process, so non-shared memory parallelism would have to cache it multiple times.

Job CentOS 8 on 764ce1c : invalidated by @joshua-cogliati-inl

Updated RAVEN to add ravenframework.ROMExternal

Commented code can be removed.

Just one change and one question. Otherwise changes look good to me.

[dylanjm]

Curious about the purpose this change.

[joshua-cogliati-inl]

Basically, this is for testing heron from a pip install, and in a pip install, %HERON% may not be anywhere near the tests directory, so I changed it to be relative to the base working directory. At some point all the tests will have to be changed to do this.

[joshua-cogliati-inl]

So after HERON is pip installed, we can:

cd tests/integration_tests/workflows/production_flex
heron heron_input.xml
raven_framework outer.xml

[dylanjm]

Changes look good and don't affect major functionality.
