(DO NOT MERGE: for reference only) Further tests of Olivier's "fix_826" branch PR 852

[valassi]

his contains further tests of Olivier's "fix_826" branch PR #852. It does not look good. I will discuss the results in PR #852 directly.

I merged the latest upstream/master into this, including the CI tmad tests.

This now has 24 failures, which should be (I did not check each one of them):

• The 9 rotxxx crashes (3 times gqttq, pptt012j, nobmppttW): THIS SHOWS PR #852 DOES NOT FIX ROTXXX CRASHES
• The 3 no cross sections (susyggt1t1)
• In addition, 12? build failures for fptype=m

FWIW I upgraded this to the latest upstream/master. But again this will not be merged.

Note: on upstream/master (before adding these extra changes in PR 870) there were 9 errors in the CI, three fptype for each of the following three issues, https://github.com/madgraph5/madgraph4gpu/pull/857#issuecomment-2194975833

• no cross section (826) in susy_gg_t1t1
• LHE color mismatch (856) in gg_ttgg
• xsec discrepancy (872) in pp_tt012j

With these extra patches in 870, there are 22 CI failures in https://github.com/madgraph5/madgraph4gpu/actions/runs/9704073463 . These seem to be the following

• 3x no cross section (826) in susy_gg_t1t1
• 3x LHE color mismatch (856) in gg_ttgg
• 3x (new?) LHE color mismatch in pp_tt012j
• 10 build failures for fptype=m
• (plus 3x GPU failures in the old CI tests)

So maybe these patches changed something in color mapping, but actually broke them further in pp_tt012j? Not sure, anyway, will investigate more

I am closing this. This is superseded by MR #873, providing several fixes in this area.
