Here is an issue to track the issue on the mainstream repo that need to be fixed before allowing to be merged in the official repo (this follows branch gpucpp_for360)

• [x] Standalone (simple test)
• [x] Madevent (tree-level) (simple test)
  • [x] compile
  • [x] correct cross-section
  • [x] check helicity
  • [x] check color selection
• [ ] Madevent (tree-level no grouping) (simple test)
  • [ ] compile
  • [ ] correct cross-section
  • [ ] check helicity
  • [ ] check color selection
• [x] loop standalone (simple test)
• [x] loop square standalone (simple test)
• [x] Madevent (loop induced)
  • [x] compile
  • [x] correct cross-section
  • [x] check helicity
  • [x] check color selection
• [x] NLO (simple test)
• [ ] unittest (mainly IOtest to update)
• [ ] acceptance test
• [x] aloha test
• [ ] plugin test

Note that fixing a point can break another one, so this will likely oscillate

acceptance test latest status (before the fix to make compile the loop-induced processes):

LOOP INDUCED

• coupling access:
  • The loop matrix-element does not have dedicated vector_id instruction
  • model has it
  • value is anyway passed correctly, so no need to specify that we always use the first value)
• had to change the signature of smatrix$id
  • changing the signature is not enough since color/helicity assignment is then buggy
  • removed the hel_buff from loop_induced (both from sum and MC over hel)
    • random_hel is obviously useless for MC over hel ...
  • add the nice fortran function to associated color
