Ciao Nicolas,
the failing tests are nothing more than just numerical instabilities which typically arise at high energies (specially if you apply a low or no cut on the jet at the born level)
In order to have the code not complaining about them, I suggest you to edit the SubProcesses/symmetry_fks_test_ME.f
and change the maximum allowed fractions of failures (line 122)
      parameter (max_fail=0.3d0)
to some larger value (I think that 0.5 should work and should be safe).
Let me know if this solves your problem.

Cheers,

Marco

FAQ #2520: “Some tests are failing in aMC@NLO runs. What is going on?”.

Hi Marco,

Thanks a lot for your answer. I raised the max_fail parameter to 0.5 and even 0.8 but still get the same error. However I am not sure that my change is being taken into account as in the output the highest failed test fraction reported is 0.37, so it should pass, right ? (Or is the normal output cut before reporting the set of tests which cause the failure ?)

I tried finding which makefile to use in order to compile symmetry_fks_test_ME.f but could not succeed. Are my modification indeed not compiled as I suspect ?

Cheers,
Nicolas.

Ciao Nicolas,
very strange indeed:
two things: can you please check that the symmetry_fks_test_ME.f files inside the P0_* directories are symbolic links to the one in SubProcesses (and therefore have the max_fail parameter set to 0.8)?
Then, in your process directory (the one which contains SubProcesses), try a ‘make clean’ before rerunning. Hopefully that should fix your problems.

Cheers,

Marco

There is indeed no Source/CutTools folder, maybe that is the problem ?

Ciao Nicolas
It is strange, there is no CutTools mentioned in the Makefile in the process directory (not the one in SubProcesses….)
What’s going on?
Cheers,

Marco

Hi Marco,

I looked inside the makefile in the process directory, and it calls the "make clean" inside Sources, which then tries to clean the CutTools directory, this is the origin of the problem for the make clean. I commented the corresponding line out and make clean now works.

However, I still get a "test failed" error message, even though the highest fraction of failures reported in the output is 0.31 so I do not know what is happening. I'll copy the output in the next comment so that you can have a look yourself.

Thanks a lot for your help.

Nicolas

Ciao Nicolas,
indeed, a bug in the make clean is there since 2.1.1
We are looking at it, sorry,

Cheers,

Marco

Thanks a lot Marco ! Everything seems to work fine now.

An error rate of 0.5 is sufficient to go to 60TeV but 100TeV requires 0.8. I am not doing precision predictions so it is not such of a problem I guess, but out of curiosity, how will this affect the reliability of the results ?

Thanks again for your help ! The MG support is great as usual.

Cheers,
Nicolas.

Thanks marco zaro, that solved my question.
