Resimulation producer

[EinarElen]

I am updating ldmx-sw, here are the details.

What are the issues that this addresses?

This resolves LDMX-Software/SimCore#49 by adding a new producer that re-simulates events based on the seeds stored in the input file.

Check List

• I successfully compiled ldmx-sw with my developments

• I ran my developments and the following shows that they are successful.

I've added an analyzer in the DQM module that compares the sim hits and particles between two passes and tested it with an ecalPN configuration.

• I attached any sub-module related changes to this PR.

Note: You do not need to make a Sub-Module PR if your submodule developments are already on that repo's default branch.

• Iss49 Initial version of a ReSimulator  SimCore#95

@EinarElen and I agreed to "hijack" this PR to do some code cleanup and reformatting within SimCore. While the newly introduced ReSimulator is not being tested by these PR Validations - it is helpful to make sure that the broad formatting/refactoring did not change any of the physics. I am not expecting it to since I trust clang to be helpful in this respect, but it is good to double check.

I am getting a python-config error from the DQM module when trying to rerun the validation:

     File "/home/runner/work/ldmx-sw/ldmx-sw/.github/validation_samples/ecal_pn/config.py", line 51, in <module>
      from LDMX.DQM import dqm
    File "/home/runner/work/ldmx-sw/ldmx-sw/install/python/LDMX/DQM/dqm.py", line 23
      DQM/python/dqm.py 
                        ^
  IndentationError: unindent does not match any outer indentation level

Maybe there is an issue with some of the updates you made when writing the DQM resim verifier? I'll leave this to your tomorrow (my tonight) and come back at it tomorrow (mine).

Hmm, I would more suspect me messing up a rebase here. I'll have a look.

The workflow_dispatch: will only be registered if the workflow on trunk has it.

[tomeichlersmith]

I used my god-like power to add workflow_dispatch: to the workflow on trunk and then put it back here. Then I was able to manually re-trigger the PR Validation run: https://github.com/LDMX-Software/ldmx-sw/actions/runs/5823063957

Unfortunately, it appears like GitHub is not registering that run as associated with this PR which is unfortunate.

[EinarElen]

Looks like the validation passed :)

[tomeichlersmith]

looks good to me - a bit worried about conflicts coming from me editing the pr_validation workflow on trunk and this branch but that will be easy for me to patch mid-merge.

(I ended up just doing a non-rebase merge locally

git fetch --all
git switch trunk
git pull
git switch SimCore49-ReSim
git pull
git merge trunk
git switch trunk
git merge SimCore49-ReSim
git push
