Add a new step in testsuite_oneprocess workflow to check MadtRex according to validation tests running the reweighting on MC samples generated using the process folders obtained during the codegen step in the CI itself.
Notice that the references files have been generated using vanilla MadGraph and not CUDACPP (like in this case) - except for nobm_pp_ttW that has been regenerated with CUDACPP - so we increased the maximum threshold for the results difference to 5%.

Make it 2% of the cross section.
Update repository to 1.01.00, in particular the MadGraph submodule got
updated to v3.6.5.
The process run originally in the ref was different from the one
included in the repository.
Reference samples have been generated using MadtRex on top of vanilla
MadGraph and not on top of CUDACPP, so there is a slightly larger
uncertainty when comparing those ref samples with the reweighted samples
that start from CUDACPP-generated events.
We are not interested to check theat they are digit-by-digit correct,
but that they are almost correct with each other.
In some cases, the imported model during reweighting is still Python 2,
so we need to setup autoconversion at the beginning of the launch card
if the model is not trivial and it is not the Standard Model

After an exchange with @zeniheisser, we decided that it may be worth to generate the event samples in advance, so that tests go a bit faster. This would imply:

  • generate and save the LHEF as some tests assets
  • compile MadtRex
  • running the executable with some cmd line args

This can be done in another workflow file separated from testsuite_oneprocess.yml, but still called by testsuite_allprocesses.yml.
